Ceph is not an acronym, so there is no official expansion like “C.E.P.H.”

The name Ceph comes from “cephalopod”—animals such as an octopus or squid. The idea fits Ceph because it can spread and manage data across many storage nodes, somewhat like many arms working together.

Kubernetes handles container orchestration, scheduling, networking, and application lifecycle management, while Ceph provides the storage layer. Ceph MON, MGR, and OSD components work together to maintain cluster health, manage the storage environment, replicate data, and provide resilient persistent storage to Kubernetes applications.

Ceph combines multiple storage servers into one distributed storage platform. It can provide RBD block storage for virtual machines and Kubernetes, CephFS for shared file storage, and RGW for S3-compatible object storage. Because data is distributed and replicated across multiple OSDs, Ceph can automatically recover from disk or server failures while keeping applications running.

Kubernetes and Ceph provide a scalable, highly available, cloud-native platform for running stateful applications such as databases, monitoring systems, logging platforms, and other enterprise workloads.
