Spring Cloud - Netflix OSS Example

Introduction

This repo contains an example of Sping cloud (Netflix OSS) micro-services architecture.

The main objective is to understand the spring cloud ecosystem. The following image shows the different components of this example:

The main parts are (they each have a readme.md with more details):

1. [Eureka] (https://github.com/Oreste-Luci/netflix-oss-example/tree/master/eureka-server)
2. [Config Service] (https://github.com/Oreste-Luci/netflix-oss-example/tree/master/config-service)
3. [Turbine] (https://github.com/Oreste-Luci/netflix-oss-example/tree/master/turbine)
4. [Hystrix Dashboard] (https://github.com/Oreste-Luci/netflix-oss-example/tree/master/hystrix-dashboard)
5. [Microservice C: This is the server micro-service for service B] (https://github.com/Oreste-Luci/netflix-oss-example/tree/master/service_c)
6. [Microservice B: This is the server micro-service for service A] (https://github.com/Oreste-Luci/netflix-oss-example/tree/master/service_b)
7. [Microservice A: This is the client micro-service] (https://github.com/Oreste-Luci/netflix-oss-example/tree/master/service_a)
8. Zuul
9. Spring Cloud Dashboard
10. RabbitMq for histryx stats aggregator
11. Docker Compose

The services can be started in any other but it recommended to start them in above order.

Service A exposes endpoints that in turn call service B endpoints and service B will call service C endpoints. The client services find the server services via Eureka.

There is further documentation for each component in the links above.
