GraalVM: Build Native Images (GVMF)


Course Overview

In this course, you will learn how to build your microservices as native executables by using GraalVM ahead of time compilation.

The JVM is not suited for running containerized microservices. The startup time is too slow and the memory footprint too high. The revolutionary GraalVM however lets you build your microservices as native images which leads to fantastic results: up to 50x faster startup time and up to 5x smaller memory footprint. The microservice frameworks Helidon, Quarkus, Micronaut, and Spring Boot are integrated with GraalVM. The others are expected to follow soon.

Building native executables can sometimes be challenging. Native Image uses a different way of executing Java programs than users of a common JVM are used to. It distinguishes between image build time and image run time. All code is known at image build time. No code can be loaded at runtime. What’s about dynamic class loading, reflection, dynamic proxy, JNI, serialization, security, debugging, and monitoring? In this course, you will learn how to build native images and handle these challenges.
