Watch Koray Oksay and Jeffery Sica's talk
Continuous integration is the backbone of every CNCF project, but large GitHub Actions runners can quickly become a major cost burden. To help projects build, test, and release efficiently, CNCF created a shared hosted runner platform powered by Oracle Cloud and donated infrastructure credits. In this session, Koray Oksay and Jeffery Sica take you behind the scenes of how the platform was built and how it is operated. They explain how it scales runners on demand, isolates workloads across projects, and integrates with GitHub Actions. They also share lessons learned on cost optimization, security, and community sustainability. If you maintain or contribute to a CNCF project, this talk is your backstage pass to how your CI is powered and how to get the most out of it.
Key Takeaways
- On-Demand Scaling: How the platform scales GitHub Actions runners automatically to match project demand.
- Secure Multi-Project Isolation: How workloads from different CNCF projects stay isolated on shared infrastructure.
- Sustainable CI: Lessons on cost optimization, security, and keeping shared community infrastructure viable over time.
