## What it is
Ceph is a distributed storage platform providing object, block, and file storage in a single unified cluster. It scales to petabytes with replication or erasure coding and exposes S3/Swift, RBD, CephFS, and NFS interfaces.

## Use cases
- build a self-hosted S3-compatible object store
- provide persistent block storage for Kubernetes clusters
- run a highly available distributed file system
- replace proprietary SAN storage with software-defined storage
- store large datasets with erasure coding for cost efficiency

## When to choose
- you need unified object, block, and file storage from one cluster
- you want scalable, self-healing storage on commodity hardware
- you need S3-compatible storage on-premises

## When to avoid
- you need simple single-node storage with minimal operational overhead
- your dataset fits comfortably on one machine
- you lack capacity to operate a complex distributed cluster

## Facets
- artifact type: infra-config
- maturity: stable
- function: object-storage, file-system, backup
- domain: cloud-computing, microservices, self-hosted
- platform: self-hosted, cpp
- tags: ceph, distributed-storage, s3, block-storage, erasure-coding, posix, software-defined-storage, linux, docker, kubernetes
