All the Microservices are developed using spring boot. This spring boot application will be registered with eureka discovery server.

FrontEnd React App makes requests to NGINX server which acts as a reverse proxy. NGINX server redirects the requests to Zuul API Gateway.

Zuul will route the requests to microservice-based on the URL route. Zuul also registers with eureka and gets the IP/domain from eureka for microservice while routing the request.
