Architecture Changes since Beijing

There are no significant architecture changes for OOM in the Casablanca release.

The focus is on incremental improvements in the following areas as discussed at the Casablanca Architecture F2F in Vancouver:

1. Persistent Storage
   • pluggable persistent storage technologies to expand beyond static host path configuration + NFS backend
   • evolve standardized Helm Templates (introduced in Beijing) to support global configuration and sub chart overrides of Storage Classes
   • provide support for GlusterFS as the first storage class provisioner

2. Resource Limits
   
   • apply CPU and Memory limits to Helm Charts in order to improve Pod placement based on resources available in a Kubernetes Cluster
   • OOM working with teams to gather accurate values per project
