Spring Cloud has implemented an embedded Zuul proxy to allow frontend application's proxy calls to backend services. This feature is useful for external clients, because it hides system complexity and helps to avoid the need to manage CORS and authentication concerns independently for all microservices. To enable it, you should annotate a Spring Boot main class with @EnableZuulProxy, and this forwards incoming requests to the target service. Of course, Zuul is integrated with the Ribbon load balancer, Hystrix circuit breaker, and service discovery, for example with Eureka.
