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.

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

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

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.

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

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

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

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

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.

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

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!

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.

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

He is a genius, cant stop watching his content. Thank you sir for all the value you share.

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. 🙏

Thank you for your contribution into software development community. We appreciate your effort and time spent!

Just found Java Brains and I love the clear and simple explanations! Definitely subscribing

This video Boosted me to prepare for interview in a unique way :D

Great video, it's amazing how many companies rate developers on their ability to answer these trivia questions.

Sir, Thanking you for your time and effort for making us understand concepts very clear. Your content is high quality with very good explanation. I have benefited from your teaching. Learning continues..... :)

Great video! Do more videos of this type. Feels like I learned a lot. It’s kind of like FAQ

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.

Kaushik Sir to be very honest, I was just smiling to see your smiling face when you were reacting to silly answers. Love the way you teach

Best content with java and now back with the same Microservices with the same extraordinary quality. Thank you.

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.

14:25 - 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.

Sir where were you all these days? I started my journey with Spring from your channel! Good to see you back.

We need more content like this ❤️

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.

Really enjoyed watching the way u answered ....and the sarcastic looks for wrongly answered questions 😊

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

Kaushik.. As always, pls take a bow once again for your wonderful explanation!

Thank you for teaching us an important lesson among all: "Question your source of knowledge before you take it as valid"

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

Great introductory video for the Microservices novice. Thank 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 had a good laugh watching this!! Cant thank you enough for everything that you do!

Thank you for posting sir, we are addicted to your explination.

Cool stuff you brought for the audience and I appreciate it.. Could you please also make a video on json vs xml interview question with examples/scenarios as you did for micro services.

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.

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

Thank you so much for all your priceless effort Kaushik. You are awesome!!

Hey Koushik, can you explain or create some series for these kind of question? It will be helpful to understand the concept easily. The way you explained help us to correlate and understand concepts. 👍

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!

Lots if fun! Great video as always. I always feel like I am at coffee with mate since this is sort of what we do when we are out and about. By the way.. one question mentioned Micro Services Tools. Have you ever used/ done a video on JHipster for creating microservices skeletons?

I have been downloading your videos and gaining awesome knowledge in the field of Java Engineering

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.

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.

Thanks allot Koushik for the detailed explanations. 👍

Big fan of your videos. Have seen almost all your tech videos. Have gone through all playlists of courses. Please do more of this content. It is really helpful. Course is different but these kinda question and answers really dig deep and we will get more info. Please do more of these. One suggestion as well.. Please keep in as playlist. Like Brain bytes are not present as playlist.

Throughout this video, i was laughing out loud after reading answers and watching your reaction to answers :>

I enjoy it when you slowly change your facial expression while reading those funny answers

love this type of video. It was super useful and I tried answering the questions before you to test my understanding

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!

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 👍

Woooooow, thanks Koushik

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

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?

Hahaha nice introduction ... Loved it ❤️

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.

As if you read my mind. Can't thank you enough!

Thanks Kaushik 🌸☀️. Love your teaching style

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.

Liked the video just by reading the title!! Thanks for doing this video.. I am appearing for the interview these days.. this video was helpful 🤗🤗

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.

Kaushik sir, thank u for amazing video. I see a different perspective now to prepare for an interview. Very helpful.

Please do with another set of questions. Loved it.

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.)

Gordon Ramsey of Microservices 😂. The video was spot on, thanks for sharing 👌

Thanks a lot for this Kaushik.. You seriously don't know how much it helps us..!!!

31:45 :) answer to question 19 semantic monitoring.. you are too good kaushik :)

Great, Thanks Kauhik

you are funny and smart:) good job, good coverage

You can write a book on Java. I am sure the book will be so famous that no other books on java would even get closer to it

this tutorial video is the best stress buster i got in last few months :P

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 😀.

Really Liked the explaination Sir. Thanks for this really informative video.

I'll be happy to see k8s and docker courses from you! Will get all access pass if so!

I used to visit a lot that page when i was working as Testing/QA. This video broke my heart.

Appreciate your time and effort for this. Very valuable video.

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.

Your face and personality looks exactly like a developer/software engineer and it's not an insult

Great answers :) thanks for this video. It gave me an idea how can I handle my interview!

Thank you so much, there are many things I have learned from this video!!

Excellent job, thanks for take your time

Thanks for the explanations, this was a really helpful video, congratulations!!

Other KZfaqrs : Meme review Koushik : Guru99 qna review

I just can't explain in words, thanks a ton

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.

Some Great Myths Busting Kaushik ...Kudos!!!

Answering question in simple terms, so as not to surprise the interviewer with buzz words and running away from questions.

"I hope I won't embarrass myself" but "I will embarrass the people who wrote this article" lol, great video.

31:15 semantic monitoring as explained perfectly! 🤣🤣🤣🤣🤣

Imagine how fun & interesting it would be having him as your Lead.

Have an interview on Monday..and guess what?? The Guru appears just in time. ❤️

awesome video Java Brains! 👍

we want more of this type of videos :)

This was quite helpful...keep up the good work !!
