Thanks Ashok sure we will do that 👍🙂

[@muhassinmusthafa3379]

Thanks a lot ..U r a great teacher... but one doubt..Why did we have load balanced uri for both CITIZEN-SERVICE AND VACCINATION-CENTER-SERVICE in application.yml of API_GATEWAY? We need to load balance both these services as per the flow and both are handled by Eureka..In this point of view this is fine.. but We added LoadBalanced annotation only for VACCINATION-CENTER-SERVICE main app. Is this due to VACCINATION-CENTER-SERVICE consuming CITIZEN-SERVICE and reverse case ( CITIZEN-SERVICE as its not consuming any microservice hence not included loadBalanced annotation inside CITIZEN-SERVICE) ? Can you pls comment on this

[@rizwihassan6190]

I don't think @LoadBalanced is related to that lb propert of application.yml. The lb://CITIZEN-SERVICE tells the gateway to use Spring Cloud Load Balancer to resolve the actual instances of the CITIZEN-SERVICE. This means the gateway doesn't point to a static URL but instead leverages a service registry (e.g., Eureka, Consul) to dynamically discover service instances.

[@karthikeyanrm3446]

Thank you so much but do take care of your health 👍 A long awaited video. Hope you cover the rest of the topics in Microservices please like resilience4j, centralized logging, distributed tracing, RabbitMQ etc. before deploying into a cloud provider like AWS.

how can i dynamically change or update routes when application still running,b'cz right now if i need to add more services , i have to make changes in gateway yml file then rebuild and reploy the gateway application at the same time many request might drop , how can i avoid

Thank you its wonderful explanation, now i clearly understood this gateway, One request could you make video of Kong gateway with oauth role based implementation please.

[@CodeDecode]

Sure Sanjay 👍

[@chandusekhar123]

why can't we just use service discovery itself? using service discovery too we are not remembering the port and host name for any backend Microservices right? so what exactly is the need for api gateway?

[@CodeDecode]

HI Chandu, U are not remembering host and port but u have to remember application name atleast to use Eureka / service discovery We don't want front end people to know any thing about our microservices. We just want them to call us using simple names in url and we will redirect them using simple English words to proper microservices. That work is done by gateway

[@chandusekhar123]

@@CodeDecode makes sense. Thanks a lot for clearing really appreciate it 🤝

@@CodeDecode hi can we have video on graphQL

[@yashsd247]

Thank you for this video.... I am not understanding why spring actuator dependency is added

[@CodeDecode]

Since now api gateway is the only entry point into our backend application, it's very important to monitor it's health when it's deployed. It will provides valuable insights including the count of requests, total time taken, and maximum time taken for the API response. The above figures reflect the numbers. We already have a video on actuators. Do u need url for the same??

[@akware977]

Thanks for the video, awesome explanation. can we have the video on the circuit breaker used for production? as you mentation hystrix is deprecated annotation now.

[@ShinAkuma]

This was the cleanest tutorial regarding the API gateway. But API gateway is kind of pointless without authentication and authorization right ? Would be greatful if you made some tutorials on how to achieve these, maybe using Oauth2 or something..

Yes we will integrate authentication and authorization in it soon 🙂👍
