  15. 15. Rook: Sandbox -> Incubation CN Orchestrator for distributed storage systems
  16. 16. ● v0.7 released Feb 21, v0.8 released July 18 ○ 545 commits total ● Instituted formalized project governance policies, added a new maintainer ● Rook Framework for Storage Providers ○ Makes Rook a general cloud-native storage orchestrator ○ Supports multiple new storage solutions with reusable specs, logic, policies ○ CockroachDB and Minio orchestration released in v0.8 ○ NFS, Cassandra, Nexenta, Alluxio ongoing ● Ceph support graduated to Beta maturity ● Automatic horizontal scaling by the Ceph operator ● Improved security model and support for OpenShift ● Numerous other features and improvements Progress Since Sandbox Entry 17
  17. 17. Adopters: Production Usage 18 There are additional adopters of Rook, especially those with on-premise deployments, that are not ready to share the details of their usage publicly at this time.
  18. 18. Centre of Excellence in Next Generation Networks 19 ● 20 bare-metal nodes providing 100TB, with more being added ● Heterogeneous mix of nodes with high disk density as well as compute-focused nodes ● Several databases, web applications, and a self-hosted file sharing solution “Rook is giving us a big head start in deploying cloud-native Ceph...having an operator that can help deploy and manage Ceph in a cloud-native environment is an ideal solution...gives us the ability to leverage both the storage and the extra compute capabilities of the storage-dense nodes” Raymond Maika, Cloud Infrastructure Engineer at CENGN
