Spring Boot enables us to produce standalone, production-ready Spring-based applications that are ready to run in micro service architecture. Spring Boot applications need minimum configuration and they provide versatile features, including:

• You can build standalone Spring applications that can be run directly
• You can develop the applications that follow micro service architecture
• Deliver Java Self contained applications ready for cloud deployment
• You can embed servers such as Tomcat and Jetty directly (without having to deploy the WAR files explicitly)
• Spring configurations get configured automatically wherever feasible
• They offer prejudiced starter POM files to streamline a Maven-based configuration
• They offer production-ready features, such as metrics, health checks, and externalized configurations
• They provide the ability to deploy with no code generation and no XML configuration
