<p>Spring Cloud has created an embedded Zuul proxy to ease the development of a very common use case where a UI application wants to proxy calls to one or more back end services. To enable it, annotate a Spring Boot main class with <code>@EnableZuulProxy</code>. This forwards local calls to <code>/proxy/*</code> to the appropriate service. The proxy uses Ribbon to locate an instance to forward to via Eureka. Forwarding to the service is protected by a Hystrix circuit breaker. Rules are configured via the Spring environment.
