Spring Cloud Netflix provides Netflix OSS integrations for Spring Boot apps through autoconfiguration and binding to the Spring Environment and other Spring programming model idioms. With a few simple annotations you can quickly enable and configure the common patterns inside your application and build large distributed systems with battle-tested Netflix components. The patterns provided include Service Discovery (Eureka), Circuit Breaker (Hystrix), Intelligent Routing (Zuul) and Client Side Load Balancing (Ribbon).
Spring Cloud Netflix features: Service Discovery: Eureka instances can be registered and clients can discover the instances using Spring-managed beans. Service Discovery: an embedded Eureka server can be created with declarative Java configuration. Circuit Breaker: Hystrix clients can be built with a simple annotation-driven method decorator. Circuit Breaker: embedded Hystrix dashboard with declarative Java configuration. Declarative REST Client: Feign creates a dynamic implementation of an interface decorated with JAX-RS or Spring MVC annotations. Client Side Load Balancer: Ribbon. External Configuration: a bridge from the Spring Environment to Archaius (enables native configuration of Netflix components using Spring Boot conventions). Router and Filter: automatic regsitration of Zuul filters, and a simple convention over configuration approach to reverse proxy creation.
