SO how does the ZUUL knows the details of microservices, the answer is eureka. In some blog posts, people complained about performance of Zuul and asked how Netflix scales it; we think this is the answer; as it is said, Zuul is CPU-bound :). For example, at one project I worked on, we used Eureka to find all instances of our microservices and ping them for their status (/health, /info). The placeholders are for NGINX ports and to replace upstream servers extracted from the Eureka service discovery. Besides, we plan to perform further load tests, so we decided to set our own test workbench. It handles other requests by fanning out to multiple services.

The simplified architecture of the project looks like this: Both Zuul and Spring Cloud Gateway have integrated flawlessly with Eureka service discovery.

NGINX - I have read NGINX can also be used as API gateway? A valid criticism is that we are introducing extra overhead by using Zuul via a Spring Boot application. Nginx is pretty powerful and can do API gateway type work. will the api gateway interact with Eureka for getting the appropriate microservice? AWS ALB- This can also be used for load balancing. And in fact this ZUUL is also a Eureka client where we should mark using @EnableDiscoveryClient, thats how these 2 apps(Eureka and zuul) linked. Thus which is right?
