Spring Cloud is a collection of projects like load balancing, service discovery, circuit breakers, routing, micro-proxy, etc will be given by Spring Cloud. So spring Cloud basically provides some of the common tools and techniques and projects to quickly develop some common patterns of the microservices. Basically, there are two ways to load balance the request. If you are keeping the load balancer on the client side and giving the load balancing responsibility to the client, then we called it Client-Side Load Balancing. The Spring Cloud Load Balancer library permits us to create applications that communicate with other applications in a load-balanced fashion. Using any algorithm we want, we can easily execute load balancing when making remote service calls.

In a distributed environment, services need to communicate with each other. The communication can either happen synchronously or asynchronously. Now, when a service communicates synchronously, it is better for those services to load balance the request among workers so that a single worker does not get overwhelmed. There are two ways to load balance the request. The benefit of client-side load balancing is that we do not need to have a separate component in the form of a load balancer. We do not need to have high availability of the load balancer etc. Also, we avoid the need to have extra hop from client to LB to worker to get the request fulfilled. So, we save on latency, infrastructure, and maintenance cost. Spring Cloud load balancer SLB and Netflix Ribbon are two well-known client-side load balancer which are used to handle such situation. In this tutorial, we will use Spring Cloud Load Balancer. Let us reuse the Restaurant Service which has all the information about the restaurant.
