Ceph

Serve object, block, and file workloads from one distributed storage layer

Ceph supports block devices, a distributed file system, and object access including S3-compatible use cases on top of the same distributed foundation.

Design resilience with replication and erasure coding

Operators can choose replicated or erasure-coded layouts and map data placement to server, rack, or site failure domains.

Evaluate it in 3 steps

1. Build a non-production test cluster and identify which object/block/file workloads are actually required.

2. Design nodes, disks, network, failure domains, and replication/EC policies.

3. Test failures, recovery, near-full behavior, and rolling upgrades before defining monitoring and independent backup/copy strategy.

For data-center and cloud platforms consolidating several storage services

Ceph fits environments that want VM block storage, shared files, and S3-compatible objects from one scalable cluster.

Expect substantial operational complexity and mixed file-level licensing

Ceph demands distributed-storage expertise for design, monitoring, recovery, capacity, and upgrades. The README describes most code as dual LGPL 2.1/3.0 with some BSD/public-domain code, CC-BY-SA documentation, and some GPL headers; COPYING is the authoritative file-level inventory. GitHub Releases are not the project's stable-release selection mechanism.
