Spring Boot is an open-source framework based on the Java programming language for developing microservices. Pivotal Team created it, and it's used to create independent and production-ready spring apps. Microservice is a software architecture that enables developers to create and deploy services independently. Each operating service has its own process, resulting in a lightweight paradigm for supporting business applications. Spring Boot is a fantastic platform for Java developers to create a stand-alone, production-ready spring application that can be started straight away. You may get started with only a few configurations without having to set up a full Spring configuration.
