The presentation discusses the joint effort between SIG Release, SIG Infra, and other contributors to enforce the migration of Kubernetes images from GCR to Registery. The goal is to serve images from both GCP and AWS, but the migration required manual interaction from users and bending of policies.
- Introduced Registery as a new front for all Kubernetes images to serve images from both GCP and AWS
- Enforced migration from GCR to Registery due to high risk of not having enough GCP Cloud credits for the year
- Bent policies to allow for faster migration despite the policy requiring at least 12 months for users to migrate away from stable features
- Backwards compatibility was introduced to allow for continued access to GCR
- Manual interaction from users was required for the migration

The presentation discusses the use of MicroVMs and the Liquid Metal project for a more performant and cost-effective CI model.
- MicroVMs are smaller VMs that are tailored for a specific need, resulting in almost the same speed as containers with the security of regular VMs.
- The Liquid Metal project is a set of tools to declaratively provision Kubernetes clusters on lightweight MicroVMs.
- The project is comprised of four components: Flintlock, Firecracker, Ignite, and Cortex.
- The use of MicroVMs and the Liquid Metal project can reduce overall cost, improve build times, and provide a more secure environment.
- The presenter demoed the Liquid Metal project on a Raspberry Pi cluster.
- The presenter faced network issues during the demo, but was able to resolve them with the help of AV staff.
