Rook Framework for Storage Solutions

  • Rook is more than just a collection of Operators and CRDs
  • Framework for storage providers to integrate their solutions into

cloud-native environments ○ Storage resource normalization ○ Operator patterns/plumbing ○ Common policies, specs, logic ○ Testing effort

  • Ceph, CockroachDB, Minio, Nexenta, and more...

What can Rook help you do (better) with Ceph?

  • Health checking for MONs with automatic failover
  • Simple management of Ceph Cluster, Pools, Filesystem and RGW through

Kubernetes objects.

  • Storage Selection in one central place.

Why Rook?

  • Simplifies running a storage backend by orchestrating it

○ Self managing (Health checking) ○ Dynamic provisioning of the storage

  • Abstraction (coming) to reduce developer “overhead”

○ Object Store Bucket, Database Custom Resource Definition ○ (Less) vendor lock-in through running services your own
