API GATEWAY and Microservices Architecture | How API Gateway act as a Single Entry Point?

[@ankeshverma5229]

I would say you are one of the gems in these over crowded videos on the internet..

[@prasenjitsutradhar3368]

Finally!!!................. after a decade, video on HLD, I thought the playlist was dead!

[@Blaze_Killer]

Thanks for explaining the API Gateway in microservices so clearly You made it really easy to understand how it helps manage, secure, and direct traffic between services. The examples you gave made everything click. Really helpful and practical looking forward to more videos like this.

[@amanbhagat1616]

I had also, similar kind of questions related to API gateway (e.g. if API gateway is single entry point, how does it handles requests at scale etc) You've nicely explained concepts and industry practices related API Gateway.

[@areebwadood6273]

API composition can also be done by GraphQL queries and they allow highly dynamic queries, with minimal data send over the network than a API gateway which sends predefined structure

[@gautamjangir8927]

The best Explanation in depth...Thanks a lot for the Amazing Videos.

[@chandan07talreja]

Best explanation of API Gateway. Thanks, Shreyansh! I hope you start a microservices series soon because I notice that most channels or courses jump directly into implementation without first explaining the theory.

[@आरवी-ण7भ]

Man you are doing great work in every video...pls keep up the momentum of new videos.

[@akash-kumar737]

Take a bow 🙇‍♂️ man. Very well explained ❤😊.

[@sheersendughosh]

Thanks a lot for this video! Information packed video! Learnt a lot new things, many doubts got resolved! 🙏

[@ArnavKircha]

Hats off to the explanation dude!! I work at a big PBC and these videos are gem if you dont want to invest your time in books. Still what is your source of book?

[@iamsreekanth]

Well explained and detailed documentation. Thank you very much!!!

[@akshinaxmedov3823]

Thank you sir , you made it clear

[@baburaom3626]

Thank you very much bro. making vedio on microservices

[@arshadbagwan3039]

Load Balancer vs API gate way Loade balance just distributes api calls across multiple instances API gate way serves calls to different micro services, it has intelligence to make a differentiate between microserivces. uses of API Gateway 1. API Composition Mulitple APIs can be called at same place 2. Authorization Only one time authorization call is required and it can be serve to call multiple apis 3. Rate Limiting Throttling , IP based blocking 4. Service Discovery

[@ashishnimrot9221]

Awesome ❤, Do you have hand's on for the same? So we can practical

[@divytripathy378]

Thanks a lot for this video🙏🏻

[@TradeStepByStep]

00:04 API Gateway routes client requests to correct backend services based on API endpoint. 02:43 API Gateway intelligently routes requests based on device type 05:26 API Gateway features 08:11 API Throttling and Rate Limiting 10:52 API Gateway acts as a single entry point for microservices and handles request routing and transformation. 13:37 API Gateway acts as a single entry point for routing traffic to multiple instances of microservices using load balancers. 16:21 API gateway acts as a single entry point for multiple instances of microservices in different availability zones. 18:52 API Gateway routes traffic based on user location and API type. 21:02 DNS-based load balancers distribute traffic intelligently 23:19 API Gateway acts as a single entry point for microservices architecture

[@dhruvgoel25]

Really amazing and informative content👍

[@prashantchaudhary8147]

Excellent explanation

[@rohanpatil2902]

Very well explained....good work bro 👍

[@bangbang86]

Thanks for the video, the first question that how API gateway can handle million of requests is clear to me, i.e. how does it scale horizontally. Maybe I did not understand, please correct me if I am wrong?

[@krupaharan12345]

Thanks for the details. Could you please help clarify, Service discovery in the API Gateway level, checks only the health of load balancers or the individual services too ? Is Load Balancers consults with Service Discovery to locate the active services ?

[@mayankgupta2721]

1. API Composition 2. Authentication 3. Rate limiting 4. SSL Termination

[@akashmaharana4384]

HI Shrayansh Please create a video on Back in the envelop estimation.

@@akashmaharana4384 hi kindly check the HLD playlist, its there already

Awesome dude

[@ranuchakravarti3277]

Hi bro , please make video of implementation on aws, and also if its on kubernates how it will b implemented

[@AbhishekGupta-nl7eo]

can you please provide a deployment and impl. process for better understanding thanks!

[@priyankapatil6783]

Please make a video on AWS

[@AmirthaS-b7e]

Bro, Could you please post a video for @ApiOperation annotation and documentation using swagger. Thanks in advance

[@ankushchoudhary9392]

still I have doubt, API Gateway in one particular region can have thousands of reqeust per sec, how its handling it? as API gateway is a single point of contact btw client and load balancer

[@jayeshnayee6735]

Earning opportunity laine jese kai backed apis bana ni hao database design karna ho, fronted ka kuch work

[@ShubhamSingh-re1tr]

i do have 1 doubt what would happen if suupose more millions request are coming from the same region then dns would be sending all the request to the api gateway of that region

[@nathsagar96]

Akamai is another example for dns based load balancing

[@gunam3876]

If api gateway is smart, cant we ask the gateway to route the requests directly to load balancer of appropriate services instead of look up into service discovery?

[@ConceptandCoding]

@@gunam3876 yes many new api gateways does that.

please also add this video in your udemy lld+hld course playlist

yea will do

Does this subscription continue to charge ₹199 every month?

[@rupeshjha4717]

Here I have doubt from long time, is api gateway not a single point of failure ? or is it like multiple instance of api gateway runs, if yes then there how the routing is handled ? Doubt is cleared here: kzbin.info/www/bejne/mpzKqamkoJ2Wjdk

[@quangnguyenle3695]

I have the same doubt like you too
