Introduction to Ceph and Architectural Overview
summary
Ceph is presented as a scale-out, software-defined storage stack that runs on commodity x86 and exposes S3 (RGW), block (RBD) and POSIX (CephFS) interfaces; the talk explains the CRUSH placement algorithm that gives stable, pseudo‑random data distribution so only ~1/N of data moves when a node fails, describes RBD thin provisioning and copy‑on‑write cloning for instant VM image clones, and outlines CephFS metadata servers for independently scalable metadata and data paths.
