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"
"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.
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.

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.
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. 🙏
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.
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!
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
few more cents you forgot to mention: 6) Discuss uses of reports and dashboards in the environment of Microservices CPU, memory, requests counts, errors - debugging P1 issues. 8) What are the challenges faced while using Microservices? * e2e testing * transactionality * communication via network - more expertise on different protocols (http, rest, queuing tech., ...) * potential distributed monolith (which has disadvantages of both microservices and the monolith) about skilled proffesionals - it's easier to hire and manage group of java developers instead of java+python+c# in a single company 10) Tell me the name of some famous companies which are using Microservice architecture not everybody. Constraints environments obviously not (automotive) besides that great video
What a great explanation for each of the answer with proper reasoning.And now i understood, when i go through Interview Questions, my most of the answers were incorrect...because, the funniest bits were displayed on the screen... looks like somebody just rolled on the screen to say something, instead of keeping numb.
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.
The answer for "what is spring cloud" was exactly the same answer as I used to write in my college semester exams which was the result of one night study. Just few technical terms and form a sentence and u r done :D
Hi JavaBrain Guy, ur video is great, can u please make a video answering below questions : 1) When do we need event-store in micro-service architecture? 2) Microservice metrices? 3) Can we use Kafka as a event-store? Best event-store. Best way to publish events 4) What security method use to restrict sharing services across services ? 5) Can we externalize API-Gateway ? 6) Maintaining object-state in microservice 7) Transanction management and rollback scenerios in microservices 8) Notifying client if producer api version changed . 9) Weak-schema implementation need and use?
This is why there is trust issues with the education system/study materials/resources of the country like Nepal, India where teachers has no industry expertise. So, their answers always confuses the students which results in the lack of confidence in the students. Always big fan of Koushik sir. Lots of love from Nepal.
Thank you so much for this.. whenever I refer to any interview questions and answers page, I used to feel that I am not aware of many things. but after watching this video I am more confident in myself.
I get to know more from your answer, rather reading from the website. Actually they can take your answers and put it here so that people can learn the actual answers. Also you answer is simple and easier to understand. I wish if you could post these type of interview question and answer video on a regular basis.
Kaushik O my God your expression on question two was hilarious. When I heard the question while watching the video I got the same expression. This has become my favorite video so far.
These questions sites really screw you up if you are a beginner. Thanks for frankly pointing it out and confirming I m not the only one with these thoughts 😀.
Kaushik. I recently got married. I wanted to switch my job for better package and your videos helped a lot. I got very good hike too. God bless you dear friend.
A microservice going down usually does fully bring down the larger system, if not specific APIs/functionality has zero chance of working. That cannot be avoided. The difference from a monolith is if a single microservice has an OOM error, only that service goes down and the others will recieve faults/errors from that service. Even if you had to read logs, it's easy to track down. But with mature monitoring dashboards, it should be trivial to see which microservice is having an issue that absolutely manifest in another component that depends on it. Monolith is probably considered slower to deploy in cases where you need to ensure deployment to staggered multiple hosts is safe, and if that deployment has to be rolled back it still has to be safe. Backwards compatibility with roll-back safety still non-trivial with microservices as well but the separation through APIs makes it easier to understand the limited ways things can go wrong -- assuming you don't have some other problems hidden within the microservices implementation. I'm glad I watched this video. I am confidently understanding what the industry buzzwords are. I pretty much had the same answer where I knew, or could infer what the question was talking about.
Great video! I love the format, as it makes for a nice discussion in a video on certain topics and calls out for errors as not everything on the internet is correct. Kudos! Keep it going.
Wow, this is great stuff man. I recently gave an answer in an interview about REST Apis based off an article I read earlier that day , and the interviewer was very confused. Turns out, there is a lot of either false or outdated information out there - who knew!
Monolith vs Microservice: its not about the code-base. Its about 'what gets built and deployed' ultimately. (Even a monolith can have a code base in multiple pieces, but deployed as a single thing.)
About half way through. I thought this might be yet another microservices puff vid. Personally never bothered with it but can certainly understand why you would employ them. I'm just sitting here nodding along learning a few things as well. Great content and such a realistic approach.
Please do this kind of videos a bit more. What we lack in an interview is the raw version of explanation and ofc stories and discussions helps to understand and memorise stuffs more easily
Awesome explanation. On a lighter note, I really enjoyed how you were surprised at that explanation, and so do I. But you did as usual great job explaining all questions.
A main advantage of Microservice architecture is the components are not coupled and the changes like adding, modifying and removing new services are easy and less risky.
This is what we need post 2020 - technical forums grilling each other 😂 By the way, appreciate the honesty and prompt reactions to call out the garbage answers 👍
I was waiting for you to scroll down every time to see the answers and your reactions were hilarious. Also the answers you provided were extremely useful. Thanks for an engaging video.
14:10: Monolith applications usually have a common database schema over which you build all your services. In case you need to change the database model you would need to coordinate this change with other teams and there might be changes in multiple services required. Whereas in Microservice you would update the data model and there would be no impact on other services. You only need to honour the existing API contract.
A monolithic application could be just as modularly designed as micro-services, what determine which one it is is how you build and deploy it. Most well designed and properly segregated OO applications can be split into micro-services or could be built as a monolith. Same code, different deployment strategy.

He has some series related to interview questions on his own website javabrains.io/ where you need to pay per course or monthly subscription.. I'm planning to buy the monthly one soon as I'm addicted to Kaushik's way of teaching!
You tried to answer the questions of others top 25 questions . But as a big fan of you, I am looking your list of top 25 questions and answers on microservices. May be next video topic.
Bro, thanks for all your videos. Everytime I need to learn something new I search for it on your channel first. Could you make a Spring Kafka course, please?
yes, that is the top hit for me as well. I am fortunate to see that you contradict one of these kind of websites which posts whatever the answer they like. Thank you!

* potential distributed monolith (which has disadvantages of both microservices and the monolith)
about skilled proffesionals - it's easier to hire and manage group of java developers instead of java+python+c# in a single company

Monolith vs Microservice: its not about the code-base. Its about 'what gets built and deployed' ultimately. (Even a monolith can have a code base in multiple pieces, but deployed as a single thing.)
