You should have hiring managers and recruiters reaching out to you to hire you for the job. Hey welcome everyone, we're gonna have a really
great day here. And we're going to have some cloud architect interviews, some cloud engineer interviews. And this is really about building caught architect careers or cut engineering careers because I want you to get that first cloud architect job, or that first cut engineer job. You know, interviewing is a critical part of your cloud computing, career development. And interviewing should be a critical part of your cloud computing career training, because it doesn't matter how good we are in our heads, and how much knowledge we have in our heads if we can't convince the hiring manager to hire us. So that's what we love to practice the Cloud Architect interview, the cloud engineer interview, we consider this to be some really critical tech career technical career development. And well, you know, whether you regardless
of the cloud computing job role you want, role you want, he needs to get hired, and what gets you hired as the Cloud Architect interview or the cloud engineer interview. Now, we're going to talk about the interview process. Today, I'm going to be asking each person what their background is, so I can tailor them to the interview. Here's the thing
in real life, what's on your resume is going to guide you to the correct the interview or on the correct interview, have the right stuff on your resume for which or an expert, that interview is going to go really smoothly, have the wrong stuff on your resume. And that resume in that interview is not going to go smoothly. Now my team popped it up on the screen. So I guess that means I should remind you that we have a for our resume and LinkedIn workshop that's going to make the world come to you.
You started talking about it. So I figured was printed on the screen. The world come to you to hire you, which means to interview you. So the interview becomes really great. I can get recruiters to reach out to you all day long. But you got to master the interview. And you got to have the technical skills, the business acumen, the leadership, etc. So you want that cloud engineer job, I love it, you want that cloud architect job,
I love it, we're going to help you get there. And today is going to be a good fun training session. So I want you to watch and observe others and see how you would answer the same questions. The best military strategy book at all times was called The Art of War. I'm
going to tell you right now, interviewing is warp. There's no participation trophy for participating in the interview, it's war. You either win and get hired or lose and don't. It's war. So let's take some military strategy, know yourself and know your enemy, and you will always be victorious. So, use this as an opportunity to learn yourself and others you'll learn your competition. Take stock in yourself, Could I have entered these? Could
I have done as well? Could I have done better? If not, you know, you've got to training go. So get better. So no, learn yourself, learn your competition look and see if you're prepared. And if you're not prepared, that's okay. Find the gaps. When I switched from internal medicine to tech. I spoke to about 50 recruiters and they told me this is what I needed in the
perfect network engineer. And I said this was where I'm at, filled in the gaps. What are my first interview when I've been hired? Here's the thing I can't think of a single interview I've ever been on in the last 25 years and tuck that I've not been hardware, I can't think of a single one. Because I studied the psychology the interview. I studied sociology, I studied human behavior, soft skills, leadership skills. And when you master that interview, you can show that hiring manager that you're ready to get that first cloud architect job, that first cloud engineer job, the first solution architect job, and you'll be kicking off your cloud architect career or cloud engineering career. So we're gonna have a lot of fun today. There's been some very brave volunteers coming from all over the world, living in countries throughout the world, to be with us today to help you build your best career. So I'm excited to help you guys out. I love training the world. If you aside, it's good to see
you cloud hired Tracy. Happy everyone and Hello, Friday Abaco maximum thrilled to see you again. Cloud hired and Abigail I hope your beautiful continuity is doing pretty well to Dylan, good to see you. So we're going to have a lot of time. So please do the following in the chatbox. So I know you're awake, alert and oriented. Can you give me a hashtag? tech career interview training or Cloud Architect interview training? or a cloud engineer interview training based upon the career that you desire. And that way, I'll know who you are and where
you're coming from. And while you're at it, please give me a hashtag Claude hired to an array over there in Cyprus from Nigeria think that's the coolest thing. So this is my opportunity to shamelessly plug this special show that Oh, no. Okay, I had
to get rid of him for a second. So Alonzo, and I have spent some special things coming up next next week that we need to make sure that you all join us for so next Monday on our cloud career q&a that Mike normally does. On Tuesday, on Mondays, Alonzo and I are going to kind of jump in and take a take over some things on Monday at 2pm. Eastern. Leo, if you could, can you post that link for the for the for the thing next Monday. And then also on our head in the clouds episode. Next week, we've got a very special guest. For Mike, that we're going to Yeah, so we need you to we need you all to make sure you join us. But I wanted to take that opportunity to make sure everybody's aware of it. So let
me know are there Yeah, okay. I couldn't find myself it was like, that's what happens when I have the added Remove button, I can just kind of click you click you add to there when when I need to, kind of like when you start to talk about me and data science and data analysts. I just click that mute button when you start to talk, talk about it. But usually give me a chance to pick up my cat and hug my cat, which always makes me happy, right? But see, I went a step further. I didn't just meet you I just said just kicked you out completely.
You see that the freedom that my team actually has, they can literally kick me out. That's how much trust and faith I have in my chain. Especially crooked. Anyway, so I took you off track there. Let me get to these hashtags. Before we get to
our first person. So many comments are coming in today. That's great. Let the comments come in. Let Erica sigh Oh, several minutes behind. That's how many how long it was taking me to take
off. Now, we're gonna start to get a nice following of people here. Actually, while you're at it, it takes a lot of time to do this. There's four people dedicated on my team to doing this to make sure you guys can have the best cloud computing career. You don't mind taking 30 seconds, send a tweet, make a Facebook post, make a quick LinkedIn post. I'm participating
in some cloud architect interview training. Please join us please follow us because you know what? We want to help the world get cloud hired. So see all this cloud architect interview training more cloud architect interview training Tracy make clear architect interview training.
Brian like cool. Caught hard. And Philadelphia LM in Mozambique. I love when you come here from Mozambique cloud hired? Chin do cloud hire tracing? Hey, caught hard while TRACY Well, I gotta tell you that the thing that I saw you do today was amazing. Derek used in Cloud Architect interview training. So good to see and today fab Cloud Architect interview planning. So I got I got a favorite ask if anybody that's in our Slack community, can somebody sent segment Worf a link to this. Because for those of you that aren't in our program, this is the normal time for one of our classes. So since we're not in class right now, people
are trying to figure out where we are. But if somebody could send him a message, I got it, make sure we get him in the right place. And some of my students will be here and some people from the community are here. You know,
I love putting my students, my students here. Well, for one thing, you get to see how amazing they are. But that's not the only reason. The other reason is it creates stress being live on YouTube. And an interview is stressful. So when I became a Krav Maga expert, I was learning to train the way you fight under stress. So I like to interview my students under stress. And that's what we put into class. Because if 1000s of people are watching
them, is going to be scarier. And that's the kind of stress that I want to simulate in the real interview. So when it comes down to the real interview, wow, you're prepared and you're not stretching this, if I could do in front of 1000 people. I could do it
in front of this one person. Simple, easy day. And it all comes down to being an easy day. It's easy day in your mind. It's an easy day in reality. So let's start interviewing the first person here. Oh, yeah, I got a good one for you for the first one. He didn't know what he was getting into. Okay, so let's Alright, so we got Mike, Mike on Mike. I like that. It's gonna be a radio show. All right. So I'm gonna as I told everyone else, I'm going to be taking you
guys off screen and we'll let my A candle his interview, this is kind of cool. It's like a musical chairs game. Yes, it is. And now Okay, fantastic. No, Mike, I think you're pretty new to the cloud. Is that correct? Yes. Very new. Okay. So you're new to the cloud? This is really great. What is your current background? What is it? You know best? What is your last job? Thank you, Mike for the question. So, my, my background is, I have a bachelor's degree
in neuroscience. So I took I was on the path of becoming a medical doctor, to surgeon. But then I got a job with AWS to work as an E commerce technician, okay, they exposed us to a lot of resources. So because when you're an employee, you get access to a lot of material study material. And I like to learn, I like to explore new things. So I
started, we had I think we had a system with down some time back in, so we weren't really working. And until we were told to rather get busy just learning new things. And then I started reading about, you know, the cloud computing, and so I fell in love with it. And I decided to pursue cloud. Okay. Okay, sounds good. So I'm going to try and start with the most basic fundamentals. And, you know, if all you've done a certification training up until now, if they're struggling, don't worry, there's plenty of time to learn. Plenty of time to learn. So I'm going to start with a basic basic subnetting. Question. You've got an IP address 190 2.1 68.1 28 dot 63.
Could you tell me where that's the subnet mask is? 25525525 5.252? Could you tell me where that network begins? What's the broadcast address? In which two are the usable addresses and that subnet? Fortunately, Mike, I have not been, I've never been exposed to that. Subject matter so. But if it's something that I need to learn in order to succeed, I think I would invest the time to, to learn or understand that subject matter.
Okay, so let's get into another I'll do something. On the fundamental side, when would I use a relational database versus a no SQL database? Think with relational database, you you will be dealing with the same situation where you're dealing with a customer's information that is, I guess, from the name relational, so things that have, let's say an address or important details about a customer. I think that's when you will use a relational database, but they need to know SQL. I'm not really quite sure. But I think what the relation database deals with key pairs and information, something like that. Okay.
Let's talk about load balancers. When would you use an application load balancer versus a network load balancer? Fortunately, Mike, I haven't had the opportunity to dive deep into load balancers yet. But I am also open to learning new things about it. Okay. So totally reasonable. Tell me about yourself. Thank you, Mike. So I'm Michael Michael benzo. And I'm originally from Ghana, West Africa.
And I moved to the States when I was a young teenager. And, and I completed my high school in Virginia. So Virginia is home as I went to Stafford High School and completed my high school education. And then from there, I gain admission to George Mason University in Fairfax, Virginia, where I pursued my neuroscience degree. And from an African back background or household, you know, it's usually three things either a doctor or an engineer or lawyer or lawyer. So, you know, everybody knew that I was going to pursue In the medical school medical background, so I was locked in. But then eventually, I fell in love with it, and
decided to pursue cloud computing. So I'm very new to cloud computing. Totally get that now, you said something pretty important to me. You said you fell in love with it? Why? What was it so special about it? Yes, so one thing that I really liked about it was the flexibility. Like with with the field, and, and I also felt like you didn't have it didn't require, you didn't burn out. It's not a job or field, that, you know, people that work within that field, you know, tend to burn out. And I know this, because I've also the work within the medical field, and I've been a caregiver before I've worked with have been doing like a nursing type of jobs before working hands on with people, clients, and you do get with those in those areas.
So with the it, there's a lot of flexibility, it's more of a relaxed environment. And plus, you get compensated really well, so considered all these things. And, you know, I felt that this was the right thing to. Do Mike, Mike froze.
Hello, Mike. Okay. Just a second. Hey, Mark. I'm gonna have to, since I know you can hear me, There's Mike. Okay, Mike. Hi. I am yeah, my backup internet, it took some time for me to for my internet service provider to go from AT and T to Verizon when at&t went down. Wow. Like they say, in high availability,
what is non two is one and three is greater than two. That's why I've never used one at a service provider. And I would never use a single cloud because mine just went down. Of course, Cindy's probably busy pulling some cables. Who knows? She does like to do that. So why should I hire you, Mike? Because it's a great question. Thank you, thank you should hire me because I am a highly
motivated, and very cerebral person, I like to learn. And, you know, I know that right. Now, I may not know everything. But I believe that with that. With these trades that I have, I think that it will make me you know, successful. Once I get my hands on a lot of training and resources that will help me succeed. I think I'll take advantage of them. So I believe that, you know, hiring me Will, I can eventually become an asset to the company, I don't want to just to be, I don't want to just become an employee, or somebody who is just part of the, you know, big numbers, but I really want to be an asset to the company, bring in money and profit to the company and help the company succeed.
Okay, thank you, Mike. I want to go through this interview with you. Some of it went well. And some of that were you committed some of the most serious interview sessions that you could possibly imagine. And we're gonna go through them to fundamentals wise, you're brand new to cloud technology. So don't worry about that. You answered it, honestly. which automates you may automatically made you stand out heads and shoulders above half of the people that actually lied to me in interviewing my wife. So there's that. So that was good.
Now, I probably suggest saying in the future, I'm sorry, I've not had the opportunity to learn that technology yet. But I'm highly energetic. I'm highly motivated. I'm highly enthusiastic, and I absolutely love technology. But this is not an area where I'm an expert. Having said that, if like to check my competency, we can talk about this, this and this. That
would have been a much better answer, but I'm still fine with it. Just because you were honestly to that point. And your personality was so likable. I still would have considered hiring you right to that point. And training you and I've hired somebody just like you his name was Schnoor. He had a great attitude, a great personality. He didn't know any of the skills to the job yet, but I liked him so much. I hired him. Not only did he do something incredible, he became the CEO of a company and he said springs Chromebooks to the developing world getting computers in the hands of people that could never afford a computer before.
I'm so happy I hired him. I'm so proud of who you are right then in there still going flying high with that perfect attitude. Then I asked you what you liked about technology, and you're talking about not wanting to burn out and earning money. That ended the interview
so fast, you had no idea. I love technology because it can change the way we live, work and play or something. It can make businesses more important. I've seen the way that technology can change our lives. And I'd like to be part of it. That's an answer. The second you talk
about burnout interviews over the second you talk about unhappiness in interviews over the second you have any negativity about your past employer, a past life interview was over. So that really was the death of the interview right there. So what I'd say is, I want you to think about it this way. How do you put things in the employers terms? Hiring Manager? How can I make your life better? What is it about tech that you like? Find something know that answer, even if in your mind is you want a stable job? Know that answer? Now, when you went in there, and you talked about an immigrant story of coming from West Africa to the United States, there's some power in that, like, it's not easy to come to the United States as an immigrant. Your parents are you no matter how you did, it went to the consulate
1,000,001 times how to prove something special about you, that was tough. That's the story of survival. That's a story to show your mental toughness. I might even throw that in there. As an immigrant, I know what it's like to work with nothing, and to fight for everything. And whether it's fighting for my family or fighting for my employer, I'm there. That's a powerful story. On a sidenote, I actually did my clinical pediatric rotations with this
physician, Daniel data from Ghana. And, wow, he taught me more in three months than I learned in seven years of school. Because he taught me how to diagnose with my hands, instead of running a $3,000 test for every single thing in the world. He was an incredible instructor. But yeah, the story of coming somewhere working hard to get here and building yourself up having a neuroscience degree. Great. Well, he could have done with that, as you should have said, I actually have a neuroscience degree, which enables me to better connect with people better present to people to establish better rapport, to help influence their decisions, that's your strength. So your attitude was perfect. Perfect. Now, I also want to improve your executive presence a little bit. Here's what I mean.
If I were to say, BGP is a TCP based protocol that uses port 179, reasonable, and it's all true, but if I said BGP is a path vector routing protocol, that uses TCP Port 179, it sounds stronger, more powerful, that's called executive presence. So I noticed when you're when you're a little lost, you're saying, um, as a filler word that, um, really takes a lot out of your communications. So if you make your point, pause, collect your thoughts. Make your point, pause, collect your thoughts, you'll have more executive presence, because the reason when people speak too fast, they're not considered executives, as as followed. The people that are the executives, they can speak as long as they want and people are listening. The people that are not have to get their thoughts out fast, fast, before somebody cuts them off. So I gotta tell you, as someone that grew up in around the New York Metro, and someone that talks fast, fast, fast, for me, I always try and slow it down. I don't always
do such a good job of it, by the way, but I do the best I can. But for you make a point, pause, make your next point, pause, make your next point. Obviously, we're going to do the fundamentals. But I think actually, this morning, you just signed up for my program. So I know
you're gonna get the really great fundamentals. And I'm excited. You know, a year from now, six months from now, eight months, I know your heart is an architect, it's going to be fun. And I know you're going to do great, so you take that great attitude. Add that to that neuroscience background, which is very powerful. Add the gravitas or the executive presence, you'll be called hired. But you know, you're just not there yet, but you will be. Alright, good job, Mike. Very
good job for the first time we're in the first literally taken the first step up to the plate. Alright. Let's give everybody it's a solution architect or Cloud Architect job you're looking for right? Alright, so hashtag Cloud Architect. Let's give us a hashtag cloud architect for Mike. First one. Yeah. First volunteer with us. Yeah, first volunteering. For Eddie's he first came across
this yesterday. I don't know if he first came across this yesterday. But he first the point is brand new volunteer. That's a story of mental toughness. That's a story of a winner. So yes, good job. Let's give you a hand of applause. I know where you're gonna be soon.
Yeah. All right. Well, I'm going to bring the next person in. Thank you for stepping up, Mike. And like I mentioned earlier, just go ahead and close the browser out that way, it opens up another slot for for other interviewees to step in. And we go, and I think you might recognize the next person. So we will bring in, we'll bring in Mark, Mark, you. Mark is an incredibly smart geologist. He just joined my cloud engineering program about six weeks ago. So I'm so happy to see him, Mark. Mark, how are you today?
Good, good. Very excited to be here, Mark, and you're in Texas, right. I'm in Texas, and it is hot, but it's starting to cool down just a little bit. Well, Mark, I'm honored to have you here interviewing for a cloud engineer position with Alpha Bravo, Charlie, Delta, Echo Foxtrot golf company today. It's a real pleasure to see you here. As you know, we are a cloud architect anakata engineering and a consulting firm where high growth, we've got customers all around the world, our customers demand, high availability and critical security solutions for most. So we're very happy to hear you. I heard there
was this guy named Mike Gibbs, who said, You are a great cloud engineer. And I'm honored to interview today. So Mark, could you tell me a little bit about yourself? Yeah, Mike, as you know, I'm a geoscientist use transitioning from beneath the ground to the cloud. That's because I love technology, I love learning new things. And I want to get cloud hired. So starting out, I did everything the wrong way. I listened to the wrong people. I got several cloud certifications with AWS. But I was getting no job offers. I've watched your program for over a year. And said, This guy really knows what he's talking about.
He teaches the, from the ground up from the data center to the cloud, because the cloud is basically just a virtual data center. So that's what I wanted to learn. I was a little weak on Linux. Python, wanted to get some TerraForm. So I enlisted in the cloud engineers program. And I haven't looked back. So fantastic, Mark. So let's talk about some basic networking. I'm going to start there,
we're going to work our way up. If I give you the subnet 170 2.16 dot 1.51 72.16 dot 1.5 with a 30 bit subnet mask, otherwise known as two, five 5.25 5.255252. What's the beginning address of the network address? What's the usable addresses? And what's the broadcast address for that subnet? Okay, so we're looking at a cider mask of see 192 224.
So suddenly, that's going to be 10 255255550252. Okay, so we're looking at as a subnet mask, or I'm sorry, a cider range of 255. That 255225 5.2 52? Did you say that's the mesh. Okay, so you're going to have four available networks, or four networks created. But you can only use two of them, because one is for the broadcast, and one is for the network. So basically, all you can do is set up your routers to communicate
with each other. And your first one would be 172. Was that 17? You said it was 16? I'm sorry? It was one I think I actually don't even remember. So you can make you can you can pick whether it was 16 or 17. I don't care. At this point. We're only dealing with the last octet anyway. 16 dot 1.5 was the next available host would be seven. And then the next available host after that would be eight Then we would jump to the next subnet.
Okay, well, we'll readdress that subnet mask, and I'm a little rusty on it. Okay, well, that's important. So we'll fix that. But could you tell me, what would cause me to choose a network load balancer versus an application load balancer? Yes, your network load balancer is fast, fast, fast. Whereas your application load balancer takes a look at the TCP header, the host and the path files and routes it that way. The
network load balancer just looks at the source address and the destination address. And wretched traffic that way. So it's a lot faster. Network. Load balancers are great when you're using micro services and containers. application load balancers are best when you've got different websites. When you're using API's, like your get or delete API's like that. And, but it's going to slow down. But they're, they're both great ways to provide performance and availability
and speed. You always want to have a load balancer of some kind, and maybe two or three. Okay, so let's assume I have block storage storage. And I need high performance storage storage far greater, and block storage. Let's say I need a million IO POS, which is what I get from about $150 drive NVMe drives? How can I achieve that on AWS? If the fastest IO to drive is a quarter of a million LPs? Yeah, you're right, you're not going to get that on AWS Mike, you're going to have to do that in the data center, you're going to have to chain those drives together. Like you said, your NVMe is going to give you your highest performance 6000 megabits per second, and chained several of them together and do a raid. Let's see raid, zero mirroring of
each one. That's how you're going to achieve your highest performance. And regarding Linux, if you're using VI or Vim, how do you get to the beginning of a line? What's the what's the command structure, the would press to get to the beginning of a line. I always I'm not great on vim yet. I've tried it. But I know that you just do the insert. And that that will take you to the beginning of the line, then use the arrow keys to scroll down, I know that there's several commands that you can use to go to a certain line number to exit you know, basically using the parentheses, and then typing in your command to get out of the insert mode. You can hit it again. It's a little convoluted. I'm more of a fan of the Nano editor at this point, but I know that a lot of Linux people really look down on people who don't know Vim, so I am trying to get better at it. Okay, and I'm gonna ask, you know, one last engineering question, what would go into a Hello World python script.
Print, basically, print parentheses, hello, world. Close parenthesis. And then I believe you can do an echo statement, but not quite sure. I know that the print command will probably get you there. Okay, that's actually pretty good. You're three quarters of the way there though. So that's good. Now, why should I hire you?
Mike, I bring a lot of experience, a lot of enthusiasm. Great team player. I've always loved sports. So that's part of my culture. Always willing to learn and very enthusiastic about cloud architecture, network architecture, everything around that. But again, and I do bring some leadership experience also. So that's why I think I would be an asset to
your company. Okay, thank you, Mark. So couple of things. You told me you're passionate about cloud architecture, but applying for a clean engineer job. That is a problem. because it's like
saying, I'm really passionate about nursing when you're a doctor. It's a totally different career. So Mark, I know there's much more in your head than this, but it's still going to take you a little more time. And that's okay. So, gotta be able to figure out the beginning of this. So and I gave you 172 16.1, and five, slash 30. The 190 216 dot 1.4 was the beginning of the subnet. The dot five and six are usable addresses, and that seven is the broadcast. That's okay, we're going to work on that. Now on the load balancer
piece. Realistically speaking, a network load balancer looks at the source, the TCP source, TCP or UDP source address, destination address protocol and port number. And it's fast you had that right. So for microservices, we generally use an application load balancer, not a network load balancer. So application load balancers look into the full HTTP HTTPS header, to look at things like push or get, for example, so kind of keep that in the back of your mind. So a little bit of knowledge on load balancers, no big deal, you're gonna get them. Because
it's only been six weeks or so from about as far as I can tell. And it's going to take, you know, six months or so to really train somebody. Because it's a big field, you're doing really great. On the Linux thing, you know, you probably need to know VI, you need to know like, how to actually save it, how they get to the beginning of the line, the end of the line, though, it's not there yet. But that's okay. But by the time you're done building that OpenStack cloud, you will be, I promise you that. And I would get used to using at least VI or vim because you know, when you're going to be SSH in the servers, there's a lot a lot of us use. I don't care how you do it personally. Now, there was another
Linux thing that I think I asked you, I don't even remember what it was at this point. How to print hello. Oh, no, that was yeah, that was a Python thing, actually, you know, that I was good with, because it is kind of like a print hello, world thing. I'm not a Python developer, believe me. But I've seen it in a book somewhere. And I tried to remember that because you know, that's the kind of thing that I like a lot of people say is, can you at least do that? So I think you know, it's a good start, Mark. Here's what you did.
Well, you're good presents. trusted you, which is very hard to do. Your attitude was very strong. Very, very strong. I'd like you to show more about all the problems you've been solving your whole life in geology. And all the things that go into it, making sure people don't die, making sure you don't miss calculate attention to detail, attention to detail, focus, consistency, professionalism. You're doing that as an engineer, you're going to be another engineer. It's the same thing. And I want that I want you to really talk about that. In the tech, and then it's great, but it's a very good start. Mark. It's just
a little more time. Yep. Great, Mike. Thank you. But it's a very good start. Mark. Very good start.
He feels good about things my thanks to your program. You're gonna be but I was gonna forget Chris. I was gonna say Mark forgot the quotations. Print. Parentheses, quote, hello, Space World, close quote. Close parenthesis. Marks. Oh, no. He was saying. Like Mike's probably gonna say Chris knows Chris. Chris, good. No, actually. That was a good one. That was a good one. Yeah. You can see it's different questions that I asked you because you're in, go into the cut engineering world, but don't convict architecture and engineering with your customers. They
know that. All right. So think it's very important. Are you ready for the next one, Mike? Yeah, I think we all right. Well, that was a good job. Let's get out. I guess we'll get a hashtag cloud engineer in the chat box.
We're gonna put engineer and here's the thing. When Mark told me about himself, he made a compelling. He showed focus. He should energy determination. That's the key. That part I really liked. That's at least 50% of it. All right. So I'm gonna break the next one and Mark, all you need to do is just close
the web browser and join us on YouTube. Yep. I want you to get intel and reconnaissance as possible. And yes, I called the reconnaissance apparently. All right, so I Are our next person I believe their name is Faye. Our fee may be mispronouncing it. I apologize. So ere we go, Fe and fi. Fe by the way with that name.
Oh, by the way, my dear Monica, I mean the mic. I haven't had a chance to communicate this to you. But we are separated by agency. Mike, your hometown in Greece is across from the agency. So we are. We are We are brothers from different mothers. Fantastic. Are you from Turkey? Are you from you from Turkey? Yes. Fantastic. I've been to Istanbul and absolutely loved it over there. You won't hear something even funnier about
it Fe so I was part of a martial arts delegation in Israel one day. We were there for a week studying Krav Maga. And there were like three of us that were Greek. And there were three or four Turkish people. And I went with the Greek people every night for dinner. The Turkish people went with the Turkish people overnight for dinner. We were in the same restaurant on the first day, the second day, the third day, we didn't have the time we were done.
We had the whole dinner the whole time together and lunches. It was like it was really great. We're actually swapping recipes too, because you know, the same Musa cars in both places. Yeah, yeah. So fantastic. FAA. So wonderful. Wonderful. I believe you're working to become a cloud architect. Is that correct? Yes. Okay, fantastic. And what is your background? So background is about first that I'm glad to be here I have 15 years optimizing and improving businesses. And my background, basically, the experience spans from heavily security,
to designing systems, designing databases, big data reporting. So that what I did, Mike was I did contract work on purpose, just so that I can cherry pick projects are the skills that I wanted to put under my belt. And so it basically became this career building venture going from, let's say, sort of being like to start out as I was in charge of a wide area network, you know, basically, start from nothing, all you had was the free version of Nasus. So when I left, you know, we had firewall Viet VPN, and then security controls in place like password policy, etc. And then I went to work for Hewlett Packard where I was basically building systems or designing systems for big three, because Hewlett Packard was basically outsourcing all the basically server maintenance from big three, and then I went to work for airways, were on, you know, building basically architecting, secure websites, designing databases, rolling out ERP systems, for, you know, a manufacturing company, and then, you know, a lot of work on the governance Risk and Compliance space, which is under cybersecurity. So I think that I'm heavy on the security mic, but what I noticed in the
last few weeks was weakness in networking. So I am knee deep in networking, I order the books that you recommended, from Halabi. Yes, Halabi. And the other Did you know the guy basically just going heavy there, but I know that this, the journey is going to take time because of that. So what I'm trying to do is get something going in the cybersecurity
architect, perhaps, and I continue on your program. And meanwhile, I started my master's in finance, and I can tell you why etc. But that's also happening in the meantime. Oh, okay. So I was actually trying to ask the question to figure out what you did. So I knew how to guide this interview. I'm still not I'm, I'm completely confused with what you've done. Because it sounds like a little of this and a little of this and a little
of this. So I'm going to basically base it on a cloud architect interview can be a standard one. Sounds like you've done some security stuff and database stuff. That's primarily is that what it primarily is um, You can say security as servers, databases, big data. That's not security to me. So if it's servers it's compute. If it's databases, it's something different. Is that what you would say? It's more working on servers and systems?
No, what I'm saying is I have experienced in IT security. Okay. I have experience building designing systems. I have experienced designing databases, to carry experience, building infrastructures for reporting, let's say we had a customer where we rolled out a business suite. And then the seaso. On the I mean, the CIO needed to know the you know, how much said, let's say they were making a specific section. So it's particular reporting needs. So reporting the or infrastructure. So but most of the experience I have probably is around IT security.
Okay. So let's do this. We'll start it and I'm going to ask you about IT security things. So, in 60, seconds or less, because this is where we need to establish rapport in the beginning of an interview. Could you tell me about yourself? Yes. I have, I have. I have 15 years optimizing and improving businesses. And I basically architecting and delivering solutions, cybersecurity solutions for Fortune 500. customer base, covering telecommunications, financials, retail, higher education, just just to name a few. Okay. Excellent. Could you tell me what the demilitarized zone should look like for a
web application? Assuming it's a critical security environment? How should I design that demilitarized zone? Yes. So that will be typically I imagine high availability is also your prime absolutely critical? Yes. Yes. In that case, what we will do Mike is you will, you will, you will have a firewall where? Okay, so you, you, you need DMZ only for the web services, alright, just for the web servers. Okay. So that's, that's pretty easy. So when I say easy, basically, what we are doing is
taking the firewall, creating the subnet, locking down that subnet, and allowing only traffic through, let's say, 443. And perhaps it'll say ad. What that means is you have the firewall. And you want the firewall to be basically an operation that has the IDS, IPS capabilities, okay. And then and then. And then, and then closing out everything else. And then on the web server, you could also the, you can also use a web application firewalls. Now to get around the distributed denial of service attacks, and you know, the, that's going to be part of your other like, I guess we need to stick to the DMZ. First
in terms of DMZ. The whole idea is you're locking down the subnet, you are allowing on the certain ports, in this case, web servers, and we talked about 443 and ad. And and, and that's, that's, you know, and when we say, you know, when we talk about web server, we talk about application security, because clearly you have something that you are serving on the web server. But add security itself is, you know, a discipline by itself. That means security has to be part of the SDLC. You are doing app scanning, you are doing code reviews. So in other words development team working with the security. So even though we are just talking about DMZ, you know, when you're talking about a web server, and you're sort of exposing some application, that application security itself also is important. But the DMZ itself,
as I said, you know earlier, you're locking down the subnet, and you're basically allowing only only the port, the service that needs to be serviced. So where do I do that limitation? Where do I block the traffic to only allow those ports 80 and port 443? Let's assume I'm going to cloud versus you do that at the firewall level. That's it. Is there any other places where I'm going to lock it down? Or I'm just going to just put a rule on the firewall? I'm so I'm secure. You have the ideas, you know, secondary layer. So you have the ideas, IPS, they can then what? And then I, let's see.
Yeah. And then the this is going to okay, this is okay. So obviously, a web server is going to sit on a server. So you have to harden this operating system on that server, that server has to have Host Based firewall. Okay, well, I'm sorry. And we still haven't answered the question of how do we block the traffic going to the server? But we'll put that aside for a minute. How do we harden the server?
You basically shut down all the ports and services that are not required. And they host based firewalls is another one. And all the security groups, all the Okay. The access control lists at the at the I think that's what you're looking for access control lists at the subnet level, because that's how you control or secure subnets ACLs. So on top of the firewalls, etc, the IDS IPS ACLs. Okay. It's getting closer. Okay, good. So how does auto scaling help prevent an organization? How a company helping organizations survive a DDoS? Attack? Okay, very good question. They're typically, typically as CDN will be very helpful. In
that you basically, oh, actually, you're talking about the other scaling? Let's say a web server is compromised. Okay. So with auto scaling, you're popping up new ones. So that way, that way, you know, the one one web server being down is not going to be impacted, because you keep propping up banners. That's, that's one of the ways always CDN is another way to fight against DDoS, or distributed denial of service attacks.
Okay, so actually, that's quite good. What? And explain to me what is identity and access management? What does it truly trying to achieve? That is basically saying, who can come in to network and what resources they can access, and then tracking the activity? That's really in a sense what identity access is. So authorization, authentication, and, and tracking through logs. And if you're doing tracking, you know, then that's typically you take the logs, you dump them into a reporting system like double A, and you can visualize it and make it comfortable. In essence, that's what you do at a high level. That's what I am is, I am. So I like that. And I actually do very much so. So how do we make a high availability
fire situation firewall situation in a cloud environment? Okay, so what you do, Mike is? That's great question. So what you do is you have multiple firewalls, you front them with a load balancer. And so, so that's there's the, you know, you cut down a single point of failure right there. And then as you move forward, obviously, assuming these are next generation, firewalls, meaning the IDS, IPS capability, but you don't stop there you go one more layer. You provide another layer of IDS, IPS, with redundancy, again, in other words, you have load balancing in front of firewalls, and load balancing for other IDS, IPS. And should I stop or slide I can continue. Keep going. You're gonna get some back of on some cut AV when we're done. This is great.
Uh, so why should I hire you? Because I have I am passionate about technology, I have a ton of experience. Like I spend my you know, over 15 years basically building the experience and the wisdom basically, to solve your problem then they these are problems, the ISO for Fortune 500 customers, like the America's largest corporations and covered financials again, they many sectors. And I enjoy learning. To me, it's constantly if you're not learning, you're behind it, this
is so true in technology. And the other thing about other thing about architecture, discipline is the it, it connects technology, and finance. It's in other words, we are business consultants with a tool set of technology. And, and so I happen to be passionate about both. And,
and. And, you know, anyways, the idea that my, my, my, the I offer basically allowed value. A lot of you know, so like, but anyways, I think I've made my point. Okay, so that is pretty interesting for you. So let's go over this one is you're very competent. That's clear. Now. It took a little bit of time initially to figure out where are you competent? Or what did you just have a hard time explaining it? You are reasonably competent, and extremely capable. And you've got all the skills right now to be an architect right
now. Now, the way you present it needs a little work still, to really get you to that level that you need to be now there's two things going on. One is, you know it home, I think of open the lights, close the lights, I don't think English is the primary language. So
if you might be thinking in Turkish and translating to English, or you might be thinking in English, but those of us who speak another language at home, there are some words that just don't translate. So there's that, but I'd say if you could get to the point quicker. You know, because you are there like if you were to say, hey, at the engineer network, for your DMZ, have a network load balance or front end to your next generation firewalls, right behind the next generation firewalls, Pa and network access control is to protect the subnet, then add a security group, then take the server patch the server, put some anti malware systems on the server, disable unnecessary services crisply, I would have known how good you were. Now it's all in your head. When I asked the questions a couple of times it all came out.
But I would say if you could formulate the answer to be crisper that would really be helpful. So on that that end to end security piece I gave you a big one actually that's a pretty big one and you did relatively good now when it came into the identity access management that was solid that was very solid when I asked you to create a high availability firewall solution that was really solid when I got into the Why should hire you It started out super super solid but you went on too long. You should hire me because I've got 15 years experience in helping businesses improve. Despite having 15 years experience I still love the tech and learn more each day. And I'd like to help you and your customers be more successful. That's why experiment. It was very solid, very solid. If you are local I'd have some kinda iffy with you. Some Baka maybe some loose icon and of course I
think a Greek salad which is probably the same thing because we're such close neighbors and I'd love to do it by the way. Where are you located? That misery Yeah, wonderful. We have another student Henry who's Nigerian living in Cyprus too. Nice letter. I think it was totally incredible. So great job fe. Thank you. Great to time. Get a little more practice and just getting it out. Film yourself on these things but
that was rock solid. Thank you. Good job. Thank you appreciate it. Have you been working with us by the way? A few weeks I think yes. Yes. Very solid two three months that's going to be super silky smooth looking forward to my take great job I'm so happy car hired let's give him caught architect cloud hired. Already I become X good perfect with the cloud hired. Oh my Yeah, I love that. Good job. Good job. So looks like we are ready for our next one. And I think you'll be familiar with this one as well. So let's bring in Alex. Just love this. This whole Mediterranean filled,
Mediterranean day last person was Turkish Alexandros in earliness, meaning he's Greek Yasu. Aleksandra has, yes, I will do this in English, because not everybody speaks fluent Greek character, or thinks in Greek, of course. So he had no Alex, and I know you, so I'm not going to ask you about your background, he's got a very good background. Tell me about yourself.
Of course, Mike. I'm a cloud architect with a focus in business transformation through technology. Previously, I worked at in the academic world, designing classroom technology. So that involves speaking to different department heads, and assessing their needs, and researching new technologies that might fit those needs and designing the classroom. While I was working there, I had the opportunity to learn computer science. And unfortunately, while I was working there, I couldn't, I didn't have the chance to change my career, because my father got sick, and he owns a restaurant. So I went to the restaurant to help my family. When when I started there, I wanted to change and transform the business to make it more efficient, and make it more profitable. So I looked into different technologies and how to do that.
Something as simple as adding a timer for toasting subs could completely change your day, or finding a solution for receiving orders through text messaging, or online ordering. And which would reduce time for workers to, you know, actually cook the food instead of talking on the phone. While I was working there, I also learned Swift programming for iOS was for iPhones. And I mainly did that for hobbyist, I did get some contract work. But it wasn't really my passion. And I wanted to focus on the family business. Now that business is coming to a close. I really wanted to focus on technology in the cloud, and change
my career again. And this is my opportunity. Alex, you said a lot of things that I love so far, you talked about transformation. And sometimes it's as simple as the timer. I consulted with a hospital and added a second ice machine. And the transformation of that made was amazing. So I like it. That's the point you're thinking, how does the tech work for somebody not just talking Tech Tech Tech? So I'm already happy to talk to you. Could you tell me you know, what is a load balancer? How does it work and why we use them? A load balancer is a hardware or software based device that increases the availability and performance of your systems. It does this increases availability by removing single
points of failure. So you'll have multiple servers attached to your load balancer and the load balancer will check in with each server with with a lot it through and a lot of time, whatever that may be, and it'll perform these health checks. So it'll ask the server, are you there? Are you there? Everyone will respond? Yes, I'm here until it's not. And when that happens, the load balancer will remove all traffic to that server and spread it among the other servers. It's the same way it increases performance as well because
it won't allow for any single server to reach 100% Before going to any other servers. Great job Alex. Wow. Could you tell me when I should use a VPN versus a private line or direct connection So in the perfect worlds, if you're looking for high availability, you'll want your data center or your cloud to have redundancy. So private line is the best option to connect
to the cloud. Because you're not going to go over the internet, so you have control over all of your, all of the traffic, you know exactly if it's going to if your traffic is going to reach the other, the other location. And if in the perfect world, you would have at least two direct direct lines or direct connect private lines, excuse me, or direct connections. And in addition, additionally, you'd have a VPN. So for use cases, you would use the VPN, maybe if you have a data center, and you have a bunch of smaller offices in different areas, you could use a VPN to make it easier, less expensive for your company to reach your data center. And the direct the private line, which in most cases would be faster, if you're connecting to your data center. It's a lot more expensive, because you're actually laying down physical cables, and it takes a longer period of time. So again,
a VPN can be can be brought up in minutes. Good. All right, good. Okay, so I have a company A, that's using a 10 dot 0.0 slash eight address space, they just buy another company B, who's also using the 10 dot 0.0, slash eight address space. So I got a great pizza, who just bought a great coffee company, the lakas Coffee Company, which might, which was my relatives. So they know what to talk to each other. And they're
using the same IP addresses? Is there a technology that we can use to get them talking to each other? You know, Mike, um, I'm not entirely sure about the question. There, I know, several technologies that could possibly work. But that's I have a kind of a basic understanding of the network and actually connecting them. So they're both private networks, private networks with the same overlapping IP address. So in my head, I'm thinking you would? Actually, I'm not sure about that. Okay, I'm gonna help I speak to you in Greek, or you need to tell your friend in English, would you do anything? You would need to translate it. Yeah. So
is there anything in the cloud and technology that will enable us to translate one address to another address? Yes, you could use network address translation. So translations in the name that I was, I was thinking, I was thinking that would be the case. So you normally use that for changing a public address to a public ed to a private and vice versa. So for a large company, you
would use port address translation or NAT overload to get multiple, all the millions because because you're using 10.0 dot 0.8 Millions of subnets. connected to one single public IP. Right, exactly. And that's the case most people think that is going to the internet but most of the use cases are actually this exact kind of situation, where a company buys another company, or it could be used as you described as not overloaded pack going to the internet. Very good, very solid. So what's the problem with using a bastion host? So Bastion house is something you never want to use in your in your business or company unless you want to get hacked. Because it's, it's wide open to the internet. And there's
a backdoor built into it. That goes to your private servers and any A hacker or anybody with a rudimentary hacking ability can hack into your system. Very true. Yeah, it's not we got some straight system in the middle of the internet. No protections on hardening. Yeah, we're gonna get hack. Nice job, Alex. So why should I hire you? Mike, you should hire me because I'm a hard worker, I spend all of my all of my extra time learning technologies, and I would work tirelessly, day and night to be able to explain questions just like you asked before, about net net. And not only that, I've run my own business. I've, I can see the business through the perspective of the owner, the employees,
the customers, partners, vendors. I can I can use digital transformation to transform your company. Wow, Alex, you're gonna bring me to tears of happiness. I'm so
