Imagine your app firing up with near-zero delays-ideal for the dynamic world of Kubernetes. By checkpointing and restoring the JVM, application performance gets supercharged by completing startup tasks before deployment, ensuring extremely rapid launches for Java applications. Open Liberty with Eclipse OpenJ9 uses CRIU to snapshot running apps, enabling rapid redeployment.

OpenJ9 CRIU Support tackles challenges like restoring multiple instances and maintaining portability, all while enhancing security without needing root privileges. Liberty InstantOn makes it effortless, letting developers achieve lightning-fast startups with minimal code tweaks.

Why It Matters:

• Instant Startups: Pre-deployment snapshots mean your app starts instantly.

• Seamless Use: Works with minimal code changes, ideal for cloud-native environments.

• Improved Security: New unprivileged mode reduces security risks by requiring fewer privileges.
  

This breakthrough means rapid app launches, seamless scaling, and an effortless developer experience, propelling Java into a new era. Curious to learn more about how we created this? Dive into the full story of how we developed the Eclipse OpenJ9 CRIU Support for fast Java startup.
