Load Balancing: Ribbon
Explore how Ribbon provides client-side load balancing for microservices by selecting instances through service discovery. Understand its integration with Spring's RestTemplate and support for Consul and Eureka. Learn strategies Ribbon uses to distribute requests and avoid single points of failure in scalable microservice architectures.
We'll cover the following...
Introduction #
Microservices have the advantage that each microservice can be scaled independently of the other microservices.
To do this, it is necessary that the call to a microservice can be distributed to several instances by a load balancer.
Central load balancer #
Typically, a single load balancer is used for all calls. Therefore, a single load balancer, which processes all requests from all microservices, can also be used for an entire microservices system.
However, such an approach leads to a bottleneck since all network traffic must be routed through this single load balancer. ...
