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!

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!

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

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 .

[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.

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.

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!

[mrmupfukudzwa]

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

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.

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.

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

[bluerose]

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

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

[SlainR]

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

[sreedhargourisetty]

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.

[richJinny]

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.

[franciscocarvalho]

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.

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.
