What is Spring Cloud?
Spring Cloud is a framework for building robust cloud applications. Spring Cloud provides a solution to the commonly encountered patterns when developing a distributed system.
Why is Spring Cloud used?
Spring Cloud framework provides tools for developers to build a robust cloud application quickly. We can also build the microservice-based applications, for example, configuration management, service discovery, circuit breakers, intelligent routing, cluster state, micro-proxy, a control bus, one time tokens, etc. Using Spring Cloud, a developer can quickly develop services and applications that implement the design patterns. These patterns work well in any distributed environment, including the bear metal data centers, developer's laptop, and managed platform such as Cloud Foundry.
Bear metal data centers: It is a physical server dedicated to a single-tenant (a person who occupies server on rent). These are not shared between the customers. The tenant can optimize the performance according to its needs for performance, security, and reliability. The bare metal data centers are also known as Single-tenant physical server or managed dedicated server. The operating system is installed directly on the bare metal server and delivers better performance.
Cloud Foundry: Cloud Foundry is an open-source, multi-cloud Platform as a Service (PaaS). You can deploy your application on your own computing infrastructure.
