KZbin is amazing. You can find very interesting videos, for free and gain tons of knowledge, for free. But, ofcourse you need a great content creater, such as you are. You deserve credits. First, you gain the knowledge, wrote a script, recorded it, made an visual video and uploaded it, thank you!

[@TechWorldwithNana]

Thanks for your appreciation Johannes!

FACTS

[@ForChiddlers]

I don't know how she can have all that knowledge from all those videos. I'd straight marry her❤

[@b3arwithm3]

It's not free. You are the product

[@ReSpawNnL]

So Nana, I am completely binge watching all your videos and I have to say, yours are simply the best out there right now. Keep up the excellent work and from the bottom of my heart, thanks for making these for the entire community and free to watch. No paywalls, just excellent, up to date, on point knowledge. You ROCK!

[@ashxos]

The best video I have seen so far on the Microservices. Great to see how you summarised so many concepts in such short period. Thanks Nana!

[@TechWorldwithNana]

Thank you! so happy to hear because that was the goal 😊

[@myriambouclier1076]

Thanks Nana it's sooo helpful !

[@kumailn7662]

true, since I found this channel I started feeling like I am a champ after seeing her videos

[@kumailn7662]

I always wanted someone like you as a mentor who when explain things, explain it actually not throwing high level terms and jargon, your videos are like a good experience university professor. You should approach some university where you can teach these topic as well.

[@beck4715]

This is genuinely the single most comprehensive piece of content I've ever seen on microservices. High level enough that I can get the full picture without getting too lost in the weeds but in depth enough that I can actually get a pretty good picture of how to implement things. Thank you, this answered a ton of questions I had! Side note: any thoughts on a polyrepo approach that also has another repo for infra and config stuff that uses git submodules to integrate everything else? I had to talk some people at work out of it because I thought it was OVERKILL for that specific project, but it seems to me like a solid approach to the problem of having repos share stuff that isn't application code.

[@sonergezgen8704]

An other complex topic very simple explained by Nana, this industry needs people like you, keep up the good work !

[@MuhammadSaaddev]

I'm a Senior Software Engineer with 7+ years of experience, always worked in backend but recently I was asked to look into devOps and miraculously, I stumbled upon your channel, I'm watching every single one of your videos and I must say that you're one of my favs, best teacher on KZbin.. I'm a Subscriber who's in love with you.

[@siriusqueen3476]

So far I find this woman the most clear and concise person to learn from on KZbin. Step by step, thank you so much for your efforts. Coming from a beginner

[@TechWorldwithNana]

Thank you Sirius, so happy to hear such positive feedback. That definitely motivates to keep on creating high quality content :)

[@Nelekochara]

im not sure if its woman

[@barry8871]

@@Nelekochara Can't you see the profile avatar and her image appear every section of the video...? Also many videos where she record herself.

[@olorundareagnes934]

Thanks a lot Nana. I now have a good grasp of what microservices means. You truly do have a way of breaking down concepts for better understanding. Thanks so much once again!

[@MohiuddinAbdulKader]

The video is truly insane. The topic and description are straightforward. So anyone can understand easily. Thank you so much for this amazing video.

[@fadior3270]

This KZbin channel has the best technical videos, thank you Nana, your content lives up to your beauty

[@narendradubey7942]

What a way of explaining the things, you just simplify the things. Thanks Nana!!

[@demiladeotunaiya5252]

Wow! I had to share this video to over 100 members of my team. This is the most explanatory video I have seen on microservices on the internet. Congrats, you have just won a subscriber and many more incoming.

[@TechWorldwithNana]

Thanks Demilade, appreciate it 😊

[@kumailn7662]

she is awesome. I always recommend to someone asking me on this topics

[@anchalsoni911]

Your grasp in the concept is amazing, you have explained everything very well. Thanks a lot Nana!

[@MVOralov]

I must admit - TechWorld with Nana - is the best spot around KZbin to get to know or to recap such things! Respect!

[@KingDaemonX]

The fact that you're my first go tutor and always come through ☺️ I don't know if this count but I love you and thank you for always coming through

[@dasabhishek]

ABSOLUTELY beautifully orchestrated video. Thank you so much for creating such videos💯

[@moazelsawaf2000]

What a great video covering almost all the important aspects 👌🏻❤ Thank you so much ❤

[@zahirsiddique747]

Excellent stuff on basic Microservices Nana, please keep up the good work as it helps a lot of people like me who are not really into coding but still need to know the "big picture" on such technologies.

[@sparklekraken5038]

Really useful video, thanks! On the Mono vs Poly Repo question, I have been investigating a 3rd option. Using individual repositories for each service, and another repo for the project itself that contains git sub-modules of each service. This keeps everything in one place for each project while allowing for code re-use of common services. But with the downside of having to make multiple updates when new versions of services are released. One to the service itself, then another to update the git sub-module.

[@ghanshyamsharma2153]

I totally love the presentation... and ur way of explaining... for absolute beginners... we can understand ur hardwork for creating such wonderful videos... thank you so much for making Digital learning easy.

[@graman4378]

Hi ! This is a great video on Microservices.. I am a veteran programmer coming from the old client-server era.... Your video on Microservices was an eye-opener for me... You have explained many things in a simple manner, something which old programmers like me can understand and appreciate... presently learning GOLANG ... I will be very thankful if you can guide me ON WHICH AMONGST YOUR VIDEOS and WHAT IS THE SEQUENCE OF THE VIDEOS that I should watch - which would be helpful to me in order for me to move slowly from 'building a single monolith web application' to 'building a MICROSERVICES application' ... Thanks once again for making this excellent video...

[@nadershalabi6241]

I just saw this and then another video, this is very well presented, clear and the time and effort put in those videos is very evident, thank you and please keep more content coming 👍

[@agyatthule717]

Excellent tutorial, concepts broken down and simplified. Easier to grasp, thank you !

[@shahabmeteor8975]

In Monorepo, we can have "several" branches for every services and manage releases through final merge to main branch.

[@vividwolfy]

Thank you so much for sharing this video, I've been working with a lot of the mentioned technologies like (Docker and CICD) in this video and I've designed my current applications with a tiered systems architecture but this video gives me a really nice approach to update my system!

[@MLLErourouwita]

Such a great video, I love how clear and well structured ❤

[@MrUmamahesh25]

Excellent video I've ever seen especially on Microservices. You cleared all my questions like why should we use Microservice and what are they with examples. Also you've explained very well about challenges at each and every stage. Presentation is very informative. I can see that you put lots of efforts to make this video. Thanks for your explanation. Thanks Nana!

[@ankushdeshmukh7731]

You are always my favorite techie Nana. simple and clear information on your channel. Cheers !!

[@flightscapeaviationphoto]

REALLY very well done... probably one of the best I've seen. Thank you. ABSOLUTE GOLD 🏆

[@HappyManRwaka]

This is one of the best videos ever watched summarizing the microservices architecture from the service creation to deployment

[@bokas5]

This video is f-ing amazing! Great job Nana! Everything is so much clearer to me now.

[@rahulsyt_]

Such an informative video. Thanks Nana, for teaching this topic in much simpler way!

[@lets_learn8843]

It was a pleasure from the first to the last minute. We're also aware of the effort behind each video. Thank you 😊!

[@TechWorldwithNana]

Thanks for your appreciation Mohamed! 💙

[@ekatherinaborunova9461]

it is the most structured and clear overview of microservices i have ever seen. thank you so much.

[@user-zh6jm1hv5p]

it's really a great video for introducing microservice. I think microservice is very useful for us to simply our application, but it also causes a lot of other problems, such as distribute transaction problem, circle dependency, and so on. so it's really hard to decide how should we split the application

[@linhquach8662]

The best video, I have seen so far on the Microservices. The way you explained easier, and full information. Thanks

[@aleksandarveselinovic5985]

As usual, you nailed it! Keep up the good work Nana!

[@rajitpaul4676]

Awesome! Thank you so much for making this so simple yet so informative.

[@sabihass5361]

This is the best video on microservices i've seen so far. Explains well and covers a lot of important topics.

[@richardroman9983]

Extremely helpful video to understand the Pros and Cons of Microservices with examples. Thanks Again for this great video!!

I started using microservices in 2000. The technology is still running strong. Thank you for the support.

[@thirstyexplorer]

Great video, Nana! 😍 Definitely worth watching it! I should probably create a video, which will be a version of mine about microservices. I enjoy so much working with microservices!

[@rohanmukherjee7107]

Great video so far, but I would like to request you to create a full playlist of microservice & its communications, any framework implementation using microservice , that would be of great help.

[@mrwaheed07]

Brilliant explanation of difficult technologies. To the point, great use of visuals, proper flow of explanation. Simply you're best. I am watching your DevOps Bootcamp in 2023. Love from Pakistan 👍

[@felixobianozie3745]

The best breakdown I have seen thus far regarding monolithic and microservices architecture. Thanks.

[@TechWorldwithNana]

Happy to hear, thanks Felix! :)

[@its_finn96]

Been waiting! Thank you!

[@angelikimessari9993]

Nana you are excellent. With you I understand concepts I struggled with for years. Thank you 🎉

[@niluparupasinghe8581]

This is indeed a great introduction to Microservices even for a beginner, thanks a lot

[@mohamedsobhy2161]

every time i search for topic or info in youtube , i find your videos .... great job.... keep on

[@spencerkormos1500]

A great video. There are several other reasons why you might want Microservices (resiliency and reduction of blast-radius), security, etc, and it probably would've been worthwhile to also touch on these even in passing reference, if not in more detail (only so much to cover in < 20 minutes!)

[@mechantl0up]

There are also reasons not to want micro services. I hear companies now moving back to monolith from micro services as well, as the former can grow overly complex when the product evolves rapidly or into unexpected directions, and suddenly it is difficult to keep together without having to write more and more tailored glue code between more and more heterogeneous services. The whole architecture turns against itself. A monolith may be much easier to grow in some cases.

[@nguyenlehuuduy6272]

I have watched your video many times to better understand Microservices , the content is very detailed and the video is excellent . Thank you so much ❤

[@bjbj7695]

Thank you Nana, you are an IT genius.

[@sommmtoooo]

Thanks Nana, Read a blog post on the monolithic architecture, then came across this video... Which just made it stick to me brain.

[@Aliaksei14]

Thank you for this video Nana, I can imagine how much time you spent on these animations. I sent it to my colleagues, maybe they will understand what global meaning microservices have, we have a monolith :(

[@bhagyalakshmi9643]

My current project is to de-couple the monolithic application and dockerise those services ... So, this video was much needed for me .. thanks a lot for share ur knowledge .

[@kesavareddy5126]

This is just awesome video,for someone like me,who is starting to learn Microservices..

[@Hasu__]

The best video for getting insights about Microservices!

[@subhransupriyaranjannayak4191]

The finest video I've seen about Microservices so far.Thanks a lot Mam.

[@eligoldberg5499]

Great video ! Small correction - a service mesh does take over the logic of communication, it's an underlying infrastructure to communicate synchronously

[@syedsaif7597]

Thanks a lot, so far the best explanation on microservices

[@user-ii3fy3rj8y]

Your lectures are so helpful to understand things from the most basic beginnings to complex ends. You explain complicated processes in easily understandable ways. Thanks a lot and May Allah (God) bless you for this.
