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!

[@vishal24000]

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.

[@ashishambre21]

Now I watched entire video I understand the honour 😄

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.

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

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!!

[@kpfingh6269]

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

[@vyshnavramesh9305]

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)

[@zameerahmed1775]

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

[@CristobalEduardoHeissJoerger]

I watched a few videos on API Gateways, this one was the best. I love how you add possible real life scenarios in the mix to get the point across. Thanks man

[@badarinaik4449]

Thanks!

[@surfbug1]

The best part (beside say man man man!) Is that this guy explains how it would happen in the real world. Thank u!

[@JustmeAgainOk]

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.

Hi Koushik, Could you please upload videos about zuul ribbon and zipkins .? Thank you.

[@prafullakh]

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.

[@kambalavijay6800]

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

[@jananipriya636]

Such an amazing Explanation! Was really able to understand what Apigee is and why it is for. Thanks for Posting this video!!

[@vishalsundararajan1228]

Good animated demonstration. Keep it up :). BTW Zuul is not a recommended solution for API Gateway because spring cloud gateway is the preferred one, we can dynamically configure routes pro-grammatically and its has better integration with Spring security oauth2. I faced a huge problem where the API's routes cannot be onboarded using a database configuration with zuul2 whereas with spring cloud gateway we can . and moreover spring team does not concentrate on zuul anymore. The main use of API gateway is the single point for authentication and authorization for all the microservices behind it and of course routing of request based on channels such a mobile, web etc.

[@praveenkumar127]

Do you have your own tutorials channel?? If yes please share it

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

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 :)

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

[@sanalalice]

You make learning fun with your examples n anecdotes..

[@ramesh4joylife]

probably the best video I had come across among the 100s I am going thru.... You explained the concept in a simple way, overlayed with not over simplified usecase but relevant business use case and finally explained the tools available in the market to do that... SAD YOU are doing only Java based videos.... pl. EXPAND......

[@pjc825]

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.

[@AnaAmOon]

simple, short, and clear. Thanks man

[@amir_tv1]

Would you put a load balancer after the API gateway as well? Like the microservices themselves would probably be replicated too.

[@palaniappanrm6277]

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?

[@Rollsroyce81]

Excellent video with very clear explanation. Thank you!

[@user-qf9nm8pn1j]

Thankyou for posting this video. I'm studying for AWS service and It's difficult to understand for me. Now I understand 60%. I need to learn English more too.

[@brendawilliams8062]

[@research8131]

Hi JavaBrains. Can you kindly explain what the most distinguishing difference between an API gateway and an ESB is? Also, are API gateways only recommended for microservices or they can be used for traditional/monolithic apps? Thank you

[@carlellis9647]

ESBs are usually used for applications within an organization to pass data back and forth between each other or to organize a specific workflow where you can orchestrate and sequence which applications and/or microservices communicate and pass information between each other. An API is specifically designed to receive a request and give a response.

[@meerapete7785]

Crisp, Cear and Concise

[@rahulsharmaoist]

how do you differentiate an api gateway with an ingress controller essentially in a kubernetes based system? Also how does API Gateway take cares of authentication? Can you please talk a little bit more on that in coming videos?

[@neelshah1943]

Exact question coming to my mind.

[@principlesoflife172]

Rate limiting also one of the feature right? Thanks for giving the overview

[@sanjivsharma366]

Is it possible to serve Web Components as a micro service, meaning API Gateway interacts with interactive Web Component which in turn gets the UI from framework from React JS framework. The React framework populates the data from other micro services - Order Service, Invoice Service, Shipping Service etc.

what is the difference between API gateway and service discovery then? do we need both or we can get rid of API gateway and just have service discovery do the mappings?

Should internal microservices also use the api gateway to communicate?

Now say we have different API Gateways for different clients viz. WebApp, Mobiles etc. Do we need to configure LB to route the request to the correct GW?

[@1manairband]

Question - when the backend micro service was split into two with the API gateway does the front end dev guy still just call the original API? Does the API gateway get updated with the new micro services for the user API? Does the front end dev guy see new stuff or just the original requested users and not session svc's? My apologies I'm a network guy trying to understand something outside my wheelhouse is all.

[@ganeshv5580]

Thank you for the awesome explaination!.
