Summary

"Instant On" for applications is highly desirable in today's cloud and serverless environments where applications should scale to zero when not in use and then create new instances immediately to handle the increased load. Join Tom and Vijay as they explore the future of instant-on for Java applications using Checkpoint/Restore in User-space (CRIU), a feature on Linux that enables one to take a snapshot of a running process. This snapshot can then be restored quickly using CRIU and resume serving application users without compromising on Java standards or peak application throughput performance. They will also demo this approach through live coding using Open Liberty (and Eclipse OpenJ9) in a container image that were released as a beta recently.
