Which software is widely used in Kubernetes environments for cloud-native storage orchestration?

• A. Rook
• B. Ceph
• C. Portworx
• D. GlusterFS

Answer: (A)

Kubernetes environments rely on a storage layer that can be provisioned and managed declaratively, just like applications. Rook is a Kubernetes-native storage orchestrator that runs inside the cluster as an operator and uses Custom Resource Definitions to manage storage backends. It typically deploys and governs Ceph, but can orchestrate other backends as well, all through the Kubernetes API. Because Rook brings storage management under the same control plane as workloads, it enables dynamic provisioning via StorageClass and persistent volumes, plus automated handling of deployment, upgrades, scaling, and recovery of the storage stack. This tight integration with the Kubernetes model is why Rook has become a widely used solution for cloud-native storage orchestration. The other options are individual storage systems or commercial offerings rather than orchestration tools built to manage storage backends from within Kubernetes. They can provide the storage itself, but they don’t offer the same Kubernetes-native orchestration layer that Rook provides.
