Continuous Integration is the backbone of every CNCF project, but large GitHub Action runners can quickly become a major cost burden. To help projects build, test, and release efficiently, we created a shared hosted runner platform, powered by Oracle Cloud and donated infrastructure credits.

In this session, we’ll take you behind the scenes of how this platform was built and operated: how it scales runners on demand, isolates workloads across projects, and integrates seamlessly with GitHub Actions. We’ll also cover lessons learned around cost optimization, security, and community sustainability.

If you maintain or contribute to a CNCF project, this is your backstage pass to understanding how your CI is powered and how you can make the most of it.
