In this chapter, we will look at some of the important patterns related to developing Cloud-Native applications and implementing them using projects under the umbrella of Spring Cloud. We will look at the following features:

• Implementing centralized microservice configuration with Spring Cloud Config Server
• Using Spring Cloud Bus to synchronize configuration across microservice instances
• Using Feign to create declarative REST clients
• Implementing client-side load balancing using Ribbon
• Implementing the Name server using Eureka
• Implementing API Gateway using Zuul
• Implementing distributed tracing using Spring Cloud Sleuth and Zipkin
• Using Hystrix to implement fault tolerance
