Spring Cloud Netflix OSS + Netflix Eureka + Netflix Ribbon Client Side Load Balancer + Example
- In this blog, we will learn to implement Client Side Load Balancing using Netflix Ribbon in Spring Boot with Spring Cloud dependencies.
- How to build a microservice based application using ribbon as Client Side Load Balancer and Netflix Eureka as registry service.
- Also, in this example we will see how we can add new instances dynamically of microservices under the load balancer. We will see how all the instances are registered on Eureka dashboard dynamically.

MicroServices Architecture Overview (Spring Cloud Netflix OSS)
Why Client Side Load Balancing?
In microservice architecture, we will have to develop many microservices. Each microservice may have multiple instances in the ecosystem as per requirement. To overcome this complexity, we have already one popular solution to use service discovery pattern. In spring boot applications, we have couple of options in the service discovery space such as netflix eureka, zookeeper etc.
To overcome the problems of traditional load balancing, client side load balancing came into picture. They reside in the application as inbuilt component and bundled along with the application, so we don’t have to deploy them in separate servers.
Technology stack
Java 8
Maven 3.5.0
Spring Boot 2.0.5.RELEASE
Eclipse
Netflix Eureka as Service Registry Server
Netflix Ribbon as Client Side Load balancerApplication Setup
ribbon-client 1 node
ribbon-eureka-server 1 node
ribbon-server 2 nodes (localhost:9090,localhost:9091)Spring Boot: ribbon-client
In this application we implemented a rest service for verifying the load balancing functionality.
