What’s New In Red Hat OpenShift 4.21?

Red Hat OpenShift 4.21 is officially GA, and the release notes are massive. But not to worry, because we’ve summed them up for you.

Whether you’re an operator keeping the lights on, or a developer pushing code, OpenShift 4.21 acts as a unified hub to manage the entire project lifecycle, from metal to model.

Key Highlights:
Achieve continuous operation for critical applications with cross-cluster live VM migration. Move running VMs between clusters for maintenance without a second of downtime.
Request GPUs based on profiles or capabilities with attribute-based GPU allocation, now generally available. Match specific project needs with expensive hardware to help eliminate hidden costs.
Reduce cloud costs by powering down unneeded capacity the moment a task finishes using autoscaling to and from zero.
Red Hat Quay 3.17 now uses a UBI 9 minimal footprint, drastically reducing "CVE noise" and vulnerability surface area.
