The Spring team provided Spring Boot on top of the Spring Framework to make Spring application development easy, by using a lot of auto-configuration for most of all modules. As Spring Boot is an extension of the Spring Core Framework, Spring Cloud is also an extension of Spring Boot, which provides various libraries and focuses on several cloud-native patterns. Spring Cloud expands on Spring Boot by giving us a bundle of libraries that improve the working of an application when added to classpath. You can exploit the basic default behavior to begin rapidly and, after that, you can design or stretch out to make a custom code.

Spring Cloud is an umbrella project of the Spring team; Spring Cloud has multiple sub-projects under it. It is the collection of the Spring sub-projects that provide solutions for cloud-native problems. These problems come into the picture when your application grows in size and traffic and also whenever you move to a mobile platform. As we have discussed in the previous section about the cloud-native application architecture, the microservices architecture is one of the solutions for cloud-native problems.

Spring Cloud gives room for coders to rapidly assemble a portion of the regular patterns in distributed systems (for example, configuration administration, circuit breakers, routing, micro-proxy, and control bus). By using Spring Cloud, coders can easily, and in no time, set applications and configurations using distributed systems. They will function great in a distributed environment, including the coder's own particular workstation, uncovered metal servers, and other platforms such as Cloud Foundry.
