What is API gateway really all about? Java Brains - Brain Bytes 

"Are you kidding me man" really helps me to remember/understand what it is about

k thanks man 😅

I'm amazed that being such a busy man, Koushik still has the time to put out such amazing videos for us! I've literally grown as a software engineer watching his videos.

When I watch a video like this, so clear, it's really difficult to imagine why someone would dislike it. Thanks for posting this Koushik!

Man, you always come up with great explanations with great examples that are really easy to catch. Thanks, man!

I have been there on other channels like telusko and all but this guy Koushik feels amazing....I dont know but I like your style Sir...the way you design your lesson plan is amazing ❤️❤️❤️❤️ Regards, A budding Developer

After watching multiple complicated and unclear videos, finally found a clear explanation on API Gateway... Thanks a lot for this crystal clear explanation!!

why is there a dislike button for this? Are you kidding me, man!??? Thanks for yet another great content! I just think your teaching style is brilliant. Very much appreciated.

Simple but detailed explanation, with an easy-to-understand real life example. Really, well done. Thanks!

Such a short & crisp explanation of API gateway. Loved it.

I'm a mechanical engineer trying to understand API gateway for a job switch..but couldnt find a simple material for my level of understanding..Finally here I've reached..clean and crisp explanation with real life scenario..making it easy to understand..thanks a lot bro!!

I really loved it, especially when the abstraction is brought into the picture and made it very easy to understand forever.

Thank so much for the great video, you are blessed with the wonderful ability of being able to explain complex things very simply and that is a very rare talent in deed. All your videos are fantastic.

Thank you so much for making this video(and for making other videos too). You explain things really well. Please continue doing so! :)

U have a heavenly voice ..... I was struggling to understand API gateways. U made it so simple. God bless you.

By not watching your videos (in time), i took "been biting the dust all along" concept to a whole new level. But then, you don't ask visitors to hit that subscribe button and press the bell icon. So a part of me is still happy that its not my fault completely. Anyway, excellent video. Thanks.

Excellent Explanation. I remember back in 2012 as Java novice I learnt Spring and Servlets from your channel, which even now is still relevant , thanks a ton. Please start a Udemy course explaining all these and much more. Excellent Content and very easy to understand. And you voice is calming and encouraging. Thank You.

I'm amazed how easily you explain all these complex concepts! hat's off :) Keep up the good work.

Good and simple explanation with advantages and disadvantages. No dogmatic stuff. Respect!

There are teachers and there are teachers! You very a GREAT teacher. You make these topics so easy to understand. Thank you very much!!!🤝🤝

Love this explanation, I watched multiple videos, but could not picture in mind what actually api gateway is , but after this video I got a clear picture , I am your fan now :)

You are soo good at explaining. I watched ur soap and rest videos and now back to watch and. Understand api gateway

Excellent!!! Great Explanation. Thank you for your valuable contribution.

Im reviewing some items for the AWS Associate exam. One of them are API gateways. I've watched many vids, and couldn't unterstand totally. Your video helped me a lot, great explanation. Thank you!

are you kidding me?? this is awesome!! many thanks Koushik!!

Crystal Clear, Thanks a lot.

You are amazing person man way you make complex architecture as simple and understable. Thank you

1. Gateway = Edge microservice = Api composition 2. What: a microservice to map apis (used by external clients) to microservices. 3. Why: loose coupling between clients and microservices. Eases lifves of frontend and backend devs. Backend dev can seperate out an MS into multiple MS without troubling frontend dev. 4. Added facilities: Monitoring, Authentication 5. eg: own microservice (if just api-microservice mapping), Zuul, Aws gateway, etc (if added facilities) 6. Cons: a) Single point of failure (solution: multiple same gateways, load balancer and elastic ips), b) Gateways are dependent on client type (solution: multiple different gaetways)

Oh man, this is simply amazing 🤣. A bit of humor makes learning these concepts much easier and more enjoyable.

Excellent video with very clear explanation. Thank you!

Great and simple explanation. Thank you so much man ♥️

Super awesome... Thank you for making it simple to understand. Cheers,... stay blessed

This is really nice video...It really helped to understand the need and what could be the problems of this and what re remedies for it. Thank you Kaushik.

Great!!! Very clear explanation 👍

So very well explained!

Thanks so much for this. I learn visually and this helped me a ton.

Great job explaining, solid video

Crisp, Cear and Concise

This was definitely quality

Awesome video. Few questions: 1. Is API gateway essentially a reverse proxy? 2. Zuul can load balance of the internal services but it needs service registry to work right? Isn't it better to use Nginx which can do lot more stuffs and we can do static routing based on the path?

Great and easy way of explaining and I have learned a lot from it thanks

Great Explanation !!

So clear, epci!

Excellent !!!!! thanks
