The Spring Boot Framework is now the platform of choice for server-side Java applications. It is characterized by a large number of available modules that cover all the requirements of modern server software. In this course, participants will learn the essential parts of Spring Boot to develop server and web applications. With Spring Boot 3 comes the long-awaited feature of native builds based on GraalVM. GraalVM can significantly improve the startup time and memory footprint of your Spring Boot applications, making them more scalable and efficient. Based on this feature, participants will learn how to create native Spring Boot applications.
