Thanks for all the nice comments! I'd like to hear your experience learning microservices. How has it been in general? Any topics or concepts that you find challenging? Please comment and let me know!

[@timetoskillup]

Hi Kaushik Sir. Can you please do a hands on tutorials for Microservices? Happy New Year !!!

[@xamael1989]

Can you do a video on how add AI and ML in web site thanks alot

sPRING mvc , SPRING SECURITY AND MICRSERVICES

[@surendarbaby]

I have been working on microservices for last five months. Though we have created n number of microservices applications ,still they are dependent on each other. Whether versioning or modified the contract of the apis. The advantage I could see is independently develop and test. Obviously scalability and zero down time when we go for cloud. Zero down time.

[@deepanshutiwari6658]

Spring security looks complex....

[@iArpanMishra]

In the second technical round, CTO asked "Arpan, what do understand about microservices?". I smiled and I freaking nailed the answer with your awesome explanation. Thanks a ton, my man! Loads of respect! EDIT: Completed one year on the job!

[@asaphakeim3614]

Awesome bro!

[@youmoufas7939]

Very good explanation

[@daayemshehzad]

Yo man I hope you got the job

[@birajg.c645]

Id be disappointed if you did not scream 'Smushed!' infront of the cto lmao

[@iArpanMishra]

@@daayemshehzad I did. Completed a year now.

[@BharCode09]

I'm a S/w engineer with 10 years Industry experience and a senior java developer since 5-7 years. Yet these videos are gem! Just refreshing to watch your videos for brushing up on some classic concepts and to feel connected. Wonderful explanation. I wish I found you 7 years ago, when I all by myself learned java with HeadFirst. Excellent service to mankind interested in java programming!

[@DhrumilShahDOTin]

Your videos helped me 5 yr back when I was in college working on my project ... After 5 yr experience still hellping me ..

[@davidranney8723]

A very concise and clear explanation of what microservices are. Thank you for unpacking the buzzword! Nicely done.

[@manishubana2107]

There are so many videos and tutorials on you tube out there but what makes you stand out are your oratory and language skills. Thank you so much .

[@StevenSokulski]

What a great video. This really helped me wrap my head around the core concepts of Microservices, and gave me a good idea of where to go next as I continue to educate myself on the subject. One important detail that helped me to understand Microservices is to start thinking about something like Twilio or Stripe or Mailgun. These services get used to serve one (or a small number) of problems for developers. Individually, none of them makes up an application. But when put together the parts become more than their sum. Microservices is a bit like treating the different responsibilities of your application as if they were, to some degree, a third-party service like Twilio.

[@mrmupfukudzwa4374]

By far the best story i have ever been told in my life! Thank you

[@LucKy-kd7fs]

Before starting the video, I couldn't even imagine that this could be explained in such a simple and *clean* manner. You explained it incredibly well. Thank you!

[@Anudeepindira]

Whenever I want to learn a new technology, the very first thing I do is to check if it is available on Java brains. Thank you Mr.Koushik for putting great effort and time into making quality videos. You make learning a joy.

[@christophersanders7483]

The best video by far I wish I had known this before. Greatest teacher of all Thank you for this great content

[@bluerose234]

First time here, and loved what I have seen and heard....will be coming back for more!!

[@rorycawley]

By far the best explanation of microservices I've seen, well done and thank you!

[@rjhrai]

I have watched a lot of your vids, since a few years already. I really appreciate them, especially the way you explain and the (peaceful) way you talk. Please continue posting your vids.

[@SlainR2]

I`m a PHP developer, but I`m watching all your conceptual videos. It sure is the best content I find on youtube.

[@sreedhargourisetty9324]

your teaching is always awesome. To be honest in my Exp Tenure no one has explained in a crystal clear understandable format like you. you made our life easy. Kudos to you once again.

[@franciscocarvalho3676]

Let me tell something - I've already watched tons of videos (not only about this topic, but about software in general), and this was so damn great to see. Thanks for sharing all of that knowledge.

[@gauravpandey599]

Koushik, thanks for looking into Microservices. Please , upload a series of videos on Microservices Architecture, 12 Factor App, Naming Server, Cloud Bus, API Gateway, Hystrix , Feign , Ribbon, Config Server , Service to Service Communication, OAuth2 Security etc. We are eagerly waiting for it. Thanks! Again.

[@rajsekharmahapatro]

looks to be like you know more than him :-)

[@skullwise]

I just completed your Javascript tutorials...It has definitely made me smarter than when I began the course. Please do react js tutorials Kaushik.

[@Codetutor-DemystifyCoding]

This is the most succinct explanation of microservices that I have come across on KZbin. If any body in future asks for a reference video trying to understand microservices, this is the video I will ask them to watch. Good job.

[@ahmadmohammed1607]

I honestly think this is the first time of my life I watch a video from the beginning to the end w/o pausing. Amazing Explanation !! Thanks man

[@adikelkar4]

Beautifully explained! It took just 15 min to differentiate between monolith and microservice architecture. Thank you for this!

[@itsJamilAhmed]

Great intro video, I like your delivery style. On some of the disadvantages you list, they would stem from a common misconception out there that microservices exclusively communicate via REST. In fact having them also consume/produce asynchronous events, coordinated via an Event Broker can result in a far more scalable and resilient architecture. Would be great to see a future video on that. 🙂

[@monsterhuntergo]

Even after 4 years, your way of explanations are really solid gold. I can absorb the concepts well and all of them are important as well regardless of time. Thank you very much for sharing your knowledge Koushik! :)

[@tekwewt]

Just mind-blowing how you can simplify a complex concept to the understanding of even a 13 year old child. Just amazing! Thanks a lot

[@internut33]

Great explanation! I really enjoyed that. I've been promoted recently and am now in the microservice world. This was awesome. I thank you!

[@leelaprasadjagu3177]

Even though we know the concept there is always something that we get from your videos. Happy New Year Koushik!

[@merakhwab]

I have been following your tutorials on Spring, Microservices and each of them are really good! Thank you for sharing with us!

[@Name260812]

I came here to understand Micro services, but in the process got clarity of web applications which was so cloudy. You are a great communicator. Thanks.

[@preeti957]

Thanks a lot for coming back sir!! Your comeback is the best thing happened to me today! :D Sincere Thanks!!

[@vikas311jain]

Microservice videos series...great

[@anilmakwana252]

please upload video regularly .... superb video ...

[@waqasshah6331]

Finally dream come true. Need complete playlist for it. Till micro-services communication and discovery. Big fan of yours. Love from Pakistan ❤️

[@AnuD2]

This video is 4 yrs old , but it is Still helping someone like me to understand what a Microservice is and it is so well explained. Thank you .

[@amritraj2303]

Koushik, thanks so much...first video in this new year and I saw the one which I requested in my previous comments..😀😀..Expecting more videos in this area in coming months..And a very Happy New year !!

[@TrouvatkiDePercusion]

FINALLY!!!! An explanation that makes clear, rational sense. I finally get it. Thank you!!

[@bradleypring7579]

Ugh where were you when I was in college! You're teaching style, spot on. Nice work and thank you.

[@amitchauhan1505]

this person's voice is so soothing to the ears. And of course, content and explanation are also great.

[@GururajBN]

Whole new topic for someone like me who is not initiated into software. Very lucid and informative.🙏🏽

[@PravatKTimsina]

No other Tutorial can be better than this to understand the fundamental of microservices. Thank you Brother. Subscribed From NEPAL.

[@ysrajeshs]

Thank you Koushik for the Microservices Basics. Expecting a full course from you on Microservices soon.

[@aniketbharsakale2561]

making complex look simple is the toughest part which you do it so easily. simplicity at its best. keep it up. thanks for all your videos. :) cheers mate.

[@heathermary9]

THANK YOU SO MUCH!! finally someone who explains the real thing instead of beating around the bush!!

[@sohumsen6371]

Microservices tutorials coming up in the next few days and weeks I hope! Wish you a very happy new year and thanks for all the videos you have put up.

[@rajeshkumarjha007raj]

This can't get better from here. Awesome work.

[@computerprogrammingwebtech3017]

Simple and concise explanation. It takes only 15 minutes to get to know what really are microservices!

[@rishabh_gour]

This world needs more people like you

[@szeredaiakos]

I love how in one sentence you point out that they are independent applications and the very next sentence you point out that they talk to each other using a request-response pattern and "work together". The "work together" part does not compute in the context of the initial "independent" promise.

[@Sumup175]

This is what we call a proper and easy to understand with reason explanation of complex term

[@kylediamond8598]

Thanks alot man!!! I didn't skip ur ads😁 This guy is good... Watching this 2 years after.... Ans it's the only video on KZbin that explains it 100%... This was all i needed!!!

[@pravdeepsanghu7545]

I specially stopped this video to comment how beautifully this man is explaining. Each and every word is going into my head. Thank you 😌

[@itsjustanumber954]

Java Brains, thank you!! It's such a relief to hear someone with the ability to make a complex, difficult concept understandable. Such a relief!!... 👍💎

[@socialkeviv5444]

That was really a good insight of "about micro services". Kudos to such a great explanation.

[@CuteyAndy]

Literally the best channel for learning concepts. Absolutely love your content.

[@srikaraku02]

Best ever explanation on KZbin till date.

[@keithmackinen8127]

BEST DESCRIPTION EVER!!! THANK YOU!!! GOT IT FIRST TIME!!

[@benzflynn]

Good video, man. Nothing like a good presentation of the basics of microservice architecture: show the history, show the drawbacks, show the new idea and show the limits of the new idea. Most of the gurus talk as if microservices are always the way to go for web apps. But clearly you need an app of a certain scale and complexity before adopting such an architecture.

[@mastermatt963]

I have been learning about microservices at the university back in the day, but didnt get it. Until I watched this video. Thanks

[@88spaces]

Your video helps to understand the need for microservices. Thank you.

[@oweisyahya5485]

Smushed!!! with your tutorials, not only we learn how to code, but also how to explain those concepts to our teammates. Thank you Koushik.

[@swapnilgupta7891]

i have an interview tomorrow ,and i knewnothing about microservices and was looking for video which will explain it in easy way...and this video did the job perfectly..liked and subscribed!!

[@anshulabhinav13]

Well, around 11:30 , where we talk about the ease of testing & deployment of the MS, I would say that it's easier said than done. Let's say we make a small change in the Shopping Catalog service, which serves some API. This API may be consumed by the Web View app. So, when we make any change to the Shopping Catlg app, we would still need to test the Web View app as well, to make sure it still does the same thing which it used to do before. Or if it's supposed to do something new, it does that new thing correctly. So by just using the MS model, we can't totally de-couple dependent systems. Just a thought.

[@alexkantony9751]

I was blind about what microservice is. Its christal clear now. Got a nice base. thanks man.

[@kuseru]

Learned in the first 12 minutes everything about Microservices - thanks to the video and the creator! -, which got me like highspeed thinking, how to realize how I could use them! Thank you!

[@jagan1957]

This guy knows how to teach!! All these videos are gems!

[@santosh5336]

This is how things should be explained to a beginner. Some youtubers directly start with complex words which instantly makes me 🥱

[@hemakaranasinghe9332]

Just new to you channel and I am feeling very lucky to be here. Such a great effort you have put to explain these topics. Amazing work! Feels like Im attending a university lecture to complete a master degree. Thank you so much..

[@honeymotiyani2854]

Loved the way you taught this, will be looking up for some more tutorials.

[@MJ-em_jay]

I love the narrator's delivery. It's perfect.

[@anandashani9923]

This is by far the best video I have watched on Microservices.

[@bastiat6865]

Thanks. That was a much simpler and cogent explanation than most of the videos that I have attempted to watch. I made it all the way through this one, and you clarified some abstract notions for me.

[@RussCrowley]

Great explanation and clearly presented. Thanks.

[@bunnihilator]

finally... top, well explained, contextualized us what the problem was and what it solves. thank you

[@kushaltm6325]

Thank you. Thanks again for teaching us how these ideas blossomed over time.

[@dhanushkakumarage1889]

Thanks and happy new year Koushik... and also It would be great if you are planning to release a spring cloud + microservices tutorial series in future..

[@supriyajha5933]

awesome! best short Microservices video on KZbin.

[@HatefYaminiOnline]

Best explanation I’ve heard yet. So glad I found this. Thank you! Subscribed.

[@verdaf3435]

One of the best videos I have watched. You make it so easy to understand. The way you have explained it is superb. I hope to continue watching more of your videos.

[@SonicAudax]

This is one of the fascinating training videos I've ever seen!

[@sreea1504]

You are awesome , perfect explanation , and your voice is also superb , please do more videos on microservices and keep it up All the best

[@niladrisadhukhan]

Well crafted easy to grasp video. Thanks for that! Your presentations keep getting better! Hope to see more content from you!

[@yogeshsoni7353]

wonderful, crisp, concise, useful, history, why.... everything ...awesome ... thanks

[@aadityamenon4563]

Thanks! Searched Reddit and stack overflow and nobody came even close to explaining it so well!

[@nareshsajnani]

Very well explained. Always love explanations with real-world examples. Thanks a lot.

[@lepetitebonjour]

FINALLY a video on microservices that really explains the concept in a good and easy to understand fashion. Thanks a lot! I've been looking a video like this one for a long time ..

[@saritamisra5883]

Very good explanation to get the base of microservices. Seeing it evolve is the best way to understand the need for it and how it came about.

[@aselmkn7764]

Thank you very much for this simple and clear explanation! You’ve saved me so much time!

[@JackMcMotivate]

Best explanation yet. I finally get it. Thank you bud!!

[@RehmanKhan-li6ly]

Excellent way to explain the problem. So now we know what was the "need" which brought Microservices into being.

[@douniaelm1453]

Amazing work! I’ve been trying to wrap my head around this for weeks now! Thank you for this

[@victorychang1294]

Thanks for breaking down the topic clearly. Great tutorial.

[@shiwanikumari3597]

Had been waiting for ur microservices tutorial. Please upload all soon . I must say u really make it easy to understand things that too point to point. thanks Kaushik. Waiting for next videos

[@aayyaa1188]

This video makes the concepts so clear. Thank you so much.

[@rongliao9255]

Clearly explained with real-world examples! Thanks!

[@ashishkhanchandani8976]

Great Explanation. What I really liked is taking it all the way back and explaining the evolution.

[@andrewshrosbree7450]

Kaushik, although this video is informative I was hoping it would address the issue of whether a microservice is (1) a deployable code module or (2) a deployable code module including its database or (3) a logical construct relating to the deployment of auto-scaling code modules that are all served by a single underlying database. In practice I have found that deploying microservices in AWS involves the modularisation of only the code, with a monolithic database (usually in a separate subnet); the auto-scaling of both software and data appears to be an impractical pattern. I'd appreciate feedback from other architects about this. BTW, your REST tutorials are the best I have ever seen. Many thanks.

[@AbhishekKumar-ub8co]

Very apt question........... looking for an answer to similar question.

[@jasons1856]

That was really interesting. I'm a EE and having to learn more about software development as time goes on. This helped.

[@swatisharma951]

So crisp and clear..Thanks for educating.

[@rajeshseptember09]

Kaushik, you're so damn good at teaching stuff man. Keep up your good work for the benefit of the community.

[@aiprompt]

This is such an amazing overview of microservices! Thank you!
