Spring Boot combines the Spring framework with Bootstrap, simplifying the process of creating Spring-based applications. It enables the rapid development of standalone, production-ready applications, particularly useful for microservices.
According to [spring.io](<http://spring.io/>), Spring Boot facilitates the creation of standalone, production-grade Spring applications that can be run easily. Developed by the Pivotal Team, it is a key tool for building microservices.
Microservices architecture allows developers to independently develop and deploy services, each with its own process. This approach supports lightweight models for business applications.
Traditional Spring has challenges, including a large framework, multiple setup steps, and handling dependencies as projects grow. Spring Boot abstracts these complexities, allowing a focus on business logic.
Spring Boot is opinionated, providing a strong starting point. It follows the convention over configuration principle, is standalone, and is production-ready, making it suitable for a wide range of applications.
Spring Boot simplifies the development of Spring applications, enhancing productivity, and reducing development time. Its opinionated nature streamlines the application setup process.
Spring Boot aims to eliminate complex XML configurations in Spring, ease the development of production-ready applications, reduce development time, and offer an easier way to start applications.
