The differences and connections between Spring Boot and Spring Cloud

Spring Boot and Spring Cloud are both extensions of the Spring Framework that can help developers build and deploy microservice applications faster, but they each have different purposes and functions.

Spring Boot is a framework for quickly building Java applications, allowing developers to create and deploy Spring-based applications faster. It provides a simple, easy-to-understand way to build stand-alone, executable Spring applications without excessive configuration. Using Spring Boot, developers can quickly select the modules they need to use to build a complete application.

Spring Cloud is a framework designed for building distributed systems. It provides a set of out-of-the-box tools to help developers implement configuration management, service discovery, load balancing, and circuit breaking for distributed architectures. Server, routing, micro-agent, control bus and other functions. It is built on Spring Boot and provides many extension modules to make the development, construction and deployment of distributed systems easier.

The main difference between Spring Boot and Spring Cloud is the usage scenario and purpose. Spring Boot is designed to create fast, simple applications, while Spring Cloud is designed for building large-scale distributed systems. In addition, Spring Cloud provides more complete solutions in terms of service registration and discovery, service fault handling, etc., which can help developers better build and deploy microservice architecture.

However, there are many connections between Spring Boot and Spring Cloud. Spring Cloud is built on Spring Boot, so users can easily use Spring Boot's functions and features, such as automatic configuration, startup dependencies, and embedded web containers. At the same time, when using Spring Cloud to build a distributed architecture, Spring Boot's rapid development and construction capabilities can speed up the development cycle and improve productivity.

In short, both Spring Boot and Spring Cloud will help developers better build and deploy microservice applications. Spring Boot focuses on rapid development and construction, while Spring Cloud focuses on solving various problems in distributed systems. The correlation and complementarity between them is very strong. Therefore, when choosing a framework that is right for them, developers need to choose which framework to use based on their needs and project size.
