 === Checkpoint and Restore With the JVM
 
-https://wiki.openjdk.org/display/crac/Main[CRaC] is an OpenJDK project that defines a new Java API to allow you to checkpoint and restore an application on the HotSpot JVM. It is based on https://github.com/checkpoint-restore/criu[CRIU], a project that implements checkpoint/restore functionality on Linux.

-The principle is the following: you start your application almost as usual but with a CRaC enabled version of the JDK like https://www.azul.com/downloads/?package=jdk-crac#zulu[the one provided by Azul]. Then at some point, potentially after some workloads that will make your JVM hot by executing all common code paths, you trigger a checkpoint using an API call, a `jcmd` command, an HTTP endpoint, or another mechanism.

-A memory representation of the running JVM, including its warmness, is then serialized to disk, allowing a very fast restoration at a later point, potentially on another machine with a similar operating system and CPU architecture. The restored process retains all the capabilities of the HotSpot JVM, including further JIT optimizations at runtime.

-Based on the foundations provided by Spring Framework, Spring Boot provides support for checkpointing and restoring your application, and manages out-of-the-box the lifecycle of resources such as socket, files and thread pools https://github.com/spring-projects/spring-checkpoint-restore-smoke-tests/blob/main/STATUS.adoc[on a limited scope]. Additional lifecycle management is expected for other dependencies and potentially for the application code dealing with such resources.
