Spring (previously known as SpringSource) was the company created by the founders of the Spring Framework (a programming model for enterprise Java applications) to support and develop Spring and related projects. Spring’s flexible and comprehensive set of extensions and third-party libraries let developers build almost any application imaginable. At its core, Spring Framework’s Inversion of Control (IoC) and Dependency Injection (DI) features provide the foundation for a wide-ranging set of features and functionality. Spring Boot combines necessities such as an application context and an auto-configured, embedded web server to make microservice development a cinch. To go even faster, one can combine Spring Boot with Spring Cloud’s rich set of supporting libraries, servers, patterns, and templates, to safely deploy entire microservices-based architectures into the cloud, in record time.
