Cloud-native microservices with Spring Boot

Spring Boot is deservedly the most popular framework in the Java world. It makes developing applications with the entire vast Spring ecosystem significantly easier and faster. With this framework, you can build applications of any size and purpose (console, streaming, web, and so on). In a microservices architecture, services face additional requirements for configuration, monitoring, diagnostics, testing, and so on. This is where Spring Boot reaches its full potential, provided you know all of its capabilities and how to use them.

Goals and objectives

  • Dig into the internals of the Spring Boot framework and its capabilities
  • Understand how to develop microservices effectively with Spring Boot and the principles of hexagonal architecture
  • Learn to use Spring Boot’s capabilities to meet the requirements for cloud-native services
  • Optimize your local Spring Boot development loop to work as efficiently as possible
