Cloud Foundry started with Droplet Execution Agents (DEAs) as the backend scheduler. Then, it was re-architected to replace DEAs with the more maintainable Diego scheduler. Today, with Eirini, Cloud Foundry allows its users to choose between Diego and Kubernetes as the underlying scheduler. Cloud Foundry operators who are considering the switch from Diego to Eirini, or to move their workloads fully to Kubernetes, may find it valuable to know the key differences in the design of the two schedulers.

In this talk we will go over the different levels of abstraction in Kubernetes and Diego, compare and contrast the two, and discuss common devops knowledge and troubleshooting tips for container schedulers.
