2. Rook Overview
• Open Sourced Nov’16 (Apache 2.0)
• Turns distributed storage software into a self-managing, self-scaling, and self-
healing storage services
• Automates deployment, bootstrapping, configuration, provisioning, scaling, upgrading,
migration, disaster recovery, monitoring, and resource management
• Uses the facilities provided by the underlying cloud-native container management,
scheduling and orchestration platform to perform its duties
• Integrates deeply into cloud native environments leveraging extension points and
providing a seamless experience for scheduling, lifecycle management, resource
management, security, monitoring, and user experience.
• Initial support for Ceph and Kubernetes – more to come with community help
• Currently in Alpha, Beta planned in the Fall, Production Ready by end of year

11. Rook and the CNCF
• Well-aligned with CNCF core principles of cloud-native systems:
container packaged, micro-services oriented, and dynamically
managed.
• Complimentary to other CNCF projects like Kubernetes and
Prometheus.
• Integrating storage services helps the CNCF offer a more complete
stack and unlock powerful scenarios around federation, portability
and multi-cloud.
