I am a big fan of Kaushik and I must say he has explained all the questions really well with few nice roasting in between and this one is the best - "I'll tell you why your business is not making more profits - because your interviewers ask these questions and hire people who give these answers"

[ritugupta]

I had an interview. I explained the same way how Kaushik explains to us regarding circuit breaker. They were amazed :D Thanks!

[ajinkyadhumal]

Started off as Kaushik's interview, but this was Kaushik testing Guru99.

[bharath]

I have laughed in amazement at some of the answers even before you reacted to it. I guess you've made me a lot smarter over the years. Thanks Kaushik.

[harshadasinha]

Your sense of humor is another level 👍🏼. Your reaction to answers were like “who gives those kind of answers”

[jamiekhoo]

"I'll tell you why your business is not making more profits - because your interviewers ask these questions and hire people who give these answers" - World-class roasting, circa 2021.

As usual great work :). Just to add about asynchronous communication as well. Microservices can communicate with each synchronously or asynchronously. Using REST API is common for synchronous communication. Using queue (RabbitMQ etc) is common for asynchronous communication between microservices. Hope this helps!

[ranarajan]

Best Content to get regarding Java, I recommend all my friends to follow your content for Java, Thank you sir for Everything.

[mkSlayer]

His reaction to every stupid answer is epic ! Never thought I'll laugh out so loud while learning about microservices ! 😂

[chanakyav]

Koushik, the way you explain things is addictive, not everyone is blessed with teaching ability..you are truly blessed and we are lucky to have you and thanks for your videos.

[blackscreen]

I Can resonate with all that you said.. Seriously if some interviewer refers these, God save the candidate.

[shekharchoudhary]

Quickest way to prepare for the interview of microservies. Thanks a lot Kaushik Sir. U r an amazing teacher.

[oprasongik]

I do not have any words to praise you!!! But I am fascinated by your extraordinary presentation and speaking technique. And the most important thing I have realized is that if you search online and learn any answer, it is not correct, you have to know which one is correct. Thank you so much for this beautiful arrangement. May Allah grants you a long and healthy life - Amen. 🙏

[akshaytank]

Well done Kaushik, you have literally roasted the blogger. Very well explained each of the points.

[dev-skills]

14:25 - In monolith architecture, you can do optimizations that are across multiple services at the project level which is not possible in case of microservices as each of them are autonomous.

[dev-skills]

8:56 Fault isolation - In case a service crashes or hardware failure happens in the infrastructure of a service, other services will continue to run. However in the case of monolithic, as everything is running in central infrastructure, hardware failure or crashes will impact multiple services.

[ProperComment]

I'm glad to visit this video, for the 1st time I see someone actually testing thier skills on the fly and making sense with arguments provided. Others content is more preped and already framed

[yuxun]

Clearly those answers were not given by person with real experience. If you ask someone who is a fan of new technologies and all the fashion words but is not a developer, he or she is very likely to give answers like these. Thank you Java Brains! I learned so much from you.

[Galaunicorn]

This way of learning technology by reacting to info from the internet becomes one of my favorite! Thank you!
