JCON 2021

As you probably already know, AOT and Graal JIT are not included by default in JDK 16. Is it all gone? Is it still possible to write your own JVMCI compiler or execute JavaScript inside the JDK? It would be nice to understand what is generally going on in the GraalVM development camp, as well as what the framework creators think. It will be useful for business to learn how the GraalVM licensing model is changing, and what alternatives have appeared now. Important changes are taking place in the area of ​​creating small container images. JDK 16 now has full musl support. But the task of minimizing the OS layer is relevant for both GraalVM and the native image, and is also successfully solved. At runtime, it is critical to understand how to measure, target, and improve the performance of microservices using the wide range of JVM and native image technologies available today. We'll cover techniques, metrics, options, and tools to help you optimize without changing your code. Overall, you will see a broader picture of the possibilities for creating the most efficient microservice containers of which Graal and its associated tools are a part.
