If you have multiple instances, suppose I have multiple instances, like, calculating one algorithm, and we have implemented it in one service, and when we want to run multiple instances, we don't have to go there to configure all the instances in the platform dynamically. In Eureka Server, when a request comes, it takes care of the instances we need to call. Using a Spring Cloud and Eureka Server, you can route the call. It is routing to call a particular system that is required.

It enables you to create applications that can start up more quickly than a standard Spring Boot application.

Spring Cloud integrates well. As it's code-based, you can do more customization. With the way you configure or code, you can have your custom implementations. It's the best integration option if you have Java Spring Web Services.
