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!
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.
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!
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!
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.
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.
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!
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 RUclips that explains it 100%... This was all i needed!!!
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.
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.
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.
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.
This is the most succinct explanation of microservices that I have come across on RUclips. 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.
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.
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! :)
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!!
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.
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.
Java brains...name itself tells us how great koushik sir ideology... Wants to see again and again because of the way you are explaining the subject ... Very clear approach to anyone
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. 🙂
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.
Cloud Computing, Microservices these words sound brand new but actually, they are not. It's all about how we architect design the system, the ideas are simple but the execution is tough! Great explanation!
Nice explanation. One thing that wasn't addressed that is key, is decoupling the microservices. In this explanation, we run the risk of creating a monolith of monoliths. Instead of one service talking to another in a synchronous fashion, architects should consider using pub/sub pattern for communication between services so that business events are published. The onus is on subscribers to listen to for businesses event. There are times when you need to make a synchronously call then you get into using Command line Query Responsibility Segration pattern within the architecture. It all hinges on the business analyst and architect correctly determining the business domain boundaries for each "application", which should be the technical authorities for a business capability.
I had gone through tons of blogs and videos about Micro Services and still did not got a clarity....This video is really superb and explained the concept in simple layman terms with right example
Awesome explanation. I was working with microservice testing but till now I never understood the exact definition of microservice as I am from non technical background (BA). But after watching this video, microservice picture is clear. Thanks a lot!
If microservices are essentially about braking up the monolith than the second most important thing is communication between them. I'd just emphasize that restful api is not a mandatory communication model. It could be anything else, not just synchronous but asynchronous as well, such as messaging. These are preferred communication models but they do not define microservices architecture. it could be event- driven, rest- driven , message- driven microservices. excellent presentation by the way.
It is so helpful to understand all about micro services. You have done great job. I really want to thank you for this great content in just 15 min video. Lots of lessen learned. I have shared this video with my friends. Once again Thanks a lot.
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!
Hi Kaushik Sir. Can you please do a hands on tutorials for Microservices? Happy New Year !!!
Can you do a video on how add AI and ML in web site thanks alot
sPRING mvc , SPRING SECURITY AND MICRSERVICES
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.
Spring security looks complex....

Awesome bro!
Very good explanation
Yo man I hope you got the job
Id be disappointed if you did not scream 'Smushed!' infront of the cto lmao
@@daayemshehzad I did. Completed a year now.

Your videos helped me 5 yr back when I was in college working on my project ...
After 5 yr experience still hellping me ..
A very concise and clear explanation of what microservices are. Thank you for unpacking the buzzword! Nicely done.
By far the best story i have ever been told in my life!
Thank you
I am Kaushik's No1 fan :-) The Bossssss is back... First comment :-)
Hi

looks to be like you know more than him :-)
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!
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 .
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 RUclips that explains it 100%... This was all i needed!!!
Simple and concise explanation. It takes only 15 minutes to get to know what really are microservices!
No other Tutorial can be better than this to understand the fundamental of microservices. Thank you Brother. Subscribed From NEPAL.
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.

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

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.
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
This is the most succinct explanation of microservices that I have come across on RUclips. 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.
THANK YOU SO MUCH!! finally someone who explains the real thing instead of beating around the bush!!
I specially stopped this video to comment how beautifully this man is explaining. Each and every word is going into my head. Thank you 😌
I`m a PHP developer, but I`m watching all your conceptual videos.
It sure is the best content I find on youtube.
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
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 .
Beautifully explained! It took just 15 min to differentiate between monolith and microservice architecture. Thank you for this!
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.
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! :)
I just completed your Javascript tutorials...It has definitely made me smarter than when I began the course. Please do react js tutorials Kaushik.
This is what we call a proper and easy to understand with reason explanation of complex term
I love the narrator's delivery. It's perfect.
Best ever explanation on RUclips till date.
I was blind about what microservice is. Its christal clear now. Got a nice base. thanks man.
this person's voice is so soothing to the ears. And of course, content and explanation are also great.
Excellent way to explain the problem. So now we know what was the "need" which brought Microservices into being.
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!!
awesome! best short Microservices video on RUclips.
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.
Your video helps to understand the need for microservices. Thank you.
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.
Thanks! Searched Reddit and stack overflow and nobody came even close to explaining it so well!
This world needs more people like you
I have been learning about microservices at the university back in the day, but didnt get it. Until I watched this video. Thanks
This can't get better from here. Awesome work.
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.
The best video by far I wish I had known this before. Greatest teacher of all Thank you for this great content
Java brains...name itself tells us how great koushik sir ideology... Wants to see again and again because of the way you are explaining the subject ... Very clear approach to anyone
By far the best explanation of microservices I've seen

Best video I have ever seen. Totally agree with the others folks who have mentioned- teaching is an art, and you have mastered it.
so far the best microservices tutorial i have come across.
Great Explanation. What I really liked is taking it all the way back and explaining the evolution.
This video made me learn more than one week of lectures on microservices!
I am not a technical person, but having lil knowledge of SW dev..but still i understood what is micro services. Because you explained it well.
Great explanation! I really enjoyed that. I've been promoted recently and am now in the microservice world. This was awesome. I thank you!

Just a thought.
The best explaination one can come up with. Thank you!
yes, very crisp and crystal clear
First time here, and loved what I have seen and heard....will be coming back for more!!
It is much beneficial for a beginner to understand the micro services. Thank you very much sir.
This is how things should be explained to a beginner.
Some youtubers directly start with complex words which instantly makes me 🥱
This guy knows how to teach!! All these videos are gems!
Cloud Computing, Microservices these words sound brand new but actually, they are not. It's all about how we architect design the system, the ideas are simple but the execution is tough! Great explanation!
Finally dream come true. Need complete playlist for it. Till micro-services communication and discovery. Big fan of yours. Love from Pakistan ❤️
Whole new topic for someone like me who is not initiated into software. Very lucid and informative.🙏🏽
Clearly explained with real-world examples! Thanks!
This is the best explanation of microservices, I have ever read!!!!!!! Thank you
By far the best explanation of microservices I've seen, well done and thank you!
Smushed!!! with your tutorials, not only we learn how to code, but also how to explain those concepts to our teammates. Thank you Koushik.
thanks Kaushik! I could listen to him for hours... about to take that challenge on!!!
Best explanation ever for Microservices, thank you for your amazing efforts wish you all the best.
The way you explained these concepts are out of words !
please upload video regularly ....
superb video ...
Nice explanation. One thing that wasn't addressed that is key, is decoupling the microservices. In this explanation, we run the risk of creating a monolith of monoliths.

Excellent articulation, simple pictures & words with a powerful message
Excellent explanation on what is the underlying reason for microservices
I had gone through tons of blogs and videos about Micro Services and still did not got a clarity....This video is really superb and explained the concept in simple layman terms with right example
Awesome explanation. I was working with microservice testing but till now I never understood the exact definition of microservice as I am from non technical background (BA). But after watching this video, microservice picture is clear. Thanks a lot!
So crisp and clear..Thanks for educating.
i love learning using stories. thanks for your explanation.
Yes, it makes the learning path more enjoyable
This video makes the concepts so clear. Thank you so much.
This is the best explanation I have gotten on this topic. Great content!
Awesome! Finally cleared what Microservices are! You are a champ man!
You explained it so well that even though i am from embedded systems domain i understood it in first go
If microservices are essentially about braking up the monolith than the second most important thing is communication between them. I'd just emphasize that restful api is not a mandatory communication model. It could be anything else, not just synchronous but asynchronous as well, such as messaging. These are preferred communication models but they do not define microservices architecture. it could be event- driven, rest- driven , message- driven microservices. excellent presentation by the way.
Best explanation yet. I finally get it. Thank you bud!!
One of the best technical and very well explained video i have ever seen!!!
The best and clear video ever on microservices :)
Very well presented. Thank you ! I would love to watch more of your tutorials.
You mastered the art of teaching my man.
Wonderfully explained
I loved the explanation around 3 to 3.5 minutes, smushed!
FINALLY!!!! An explanation that makes clear, rational sense. I finally get it. Thank you!!
This video explained the topic pretty well on a fundamental level, thank you!
This is by far the best video I have watched on Microservices.
It is the best explanation of microservices I've seen so far!
Great contents, great teacher! Just what a viewer needs to know no more no less!
It is so helpful to understand all about micro services. You have done great job. I really want to thank you for this great content in just 15 min video. Lots of lessen learned. I have shared this video with my friends.
Once again Thanks a lot.
Your way of explaining things is so clean n well articulate👌
Thank you Koushik for the Microservices Basics. Expecting a full course from you on Microservices soon.
A very good story. Loved your explanation. Few topics which I would like to listen from you....
1. Data analytics
2. IOT
3. Block Chain
4. RPA
Thanks for explaining microservices in a brief way...!!!
