Client-Side Load Balancing
In client-side load balancing, the decision about which instance of the service to route the request to is made by the client itself. This approach can be tightly integrated with service discovery.
A. Spring Cloud Netflix Ribbon:
It is an Inter-Process Communication (IPC) library in the Spring Cloud Netflix technology stack and it includes load balancing as one of its functions. It is typically used with the Eureka for service discovery. Although Ribbon is now in maintenance mode and no longer actively developed, it has been widely used for client-side load balancing. It provides several algorithms, including round-robin, Weighted Response Time, and Zone Avoidance.
B. Spring Cloud LoadBalancer:
This is a relatively new project intended to replace Netflix Ribbon. It is a lightweight client-side load balancer that provides basic load balancing across service instances. It supports pluggable algorithms and integrates cleanly with Spring Cloud Service Discovery.
Load Balancing in Spring Boot Microservices
Load balancing is an important concept in distributed systems, especially in microservice environments. As enterprises increasingly adopt cloud-native technologies, application models require complex load-balancing strategies to efficiently deliver requests to customers This ensures high availability, fault tolerance, and resource efficiency in dynamic and quality environments
