Server-Side Load Balancing
Server-side load balancing is performed by the infrastructure layer between client requests and service instances. This layer receives requests from clients and routes them to available service instances based on factors such as load, availability, and other metrics.
A. Spring Cloud Gateway:
It acts as an API gateway. Spring Cloud Gateway performs load balancing by routing requests to the appropriate backend services. It leverages Spring Cloud LoadBalancer underneath to determine the best service instance to route requests to.
B. Netflix Zuul:
Another part of the Spring Cloud Netflix stack, Zuul can act as both the gateway and a simple load balancer. It dynamically routes requests to different backend services based on various routing rules and can be combined with Eureka and Ribbon for a complete routing solution.
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
