This course aims to teach learners how to deploy Java applications in the cloud using GraalVM Native Image to achieve fast startup, low memory footprint, and optimal performance. The course covers topics such as the native image build process, minimizing resource usage, horizontal scaling of microservices, reducing vulnerability, and creating scalable microservices with frameworks like Helidon SE. Learners will also explore the differences between Just-In-Time (JIT) and Ahead-of-Time (AOT) compilation, as well as the new features and roadmap of GraalVM. The teaching method includes demos, examples, and discussions on practical applications. This course is intended for Java developers interested in optimizing their applications for cloud deployment using GraalVM technology.
