Microservices with Spring Boot
The document discusses microservices and their advantages over monolithic applications. It defines microservices as small, independent components that are built, deployed, and scaled independently. The document outlines characteristics of microservices like being organized around business capabilities, infrastructure automation, and evolutionary design. It also discusses tools that can help build microservices architectures.
