What are Ceph and MinIO?
Ceph
Ceph is a highly scalable distributed storage system that provides object, block, and file storage in a unified cluster. It is designed for fault tolerance with no single point of failure.
- Unified object, block, and file storage
- Self-healing and self-managing
- Massive scalability
MinIO
MinIO is a high-performance, S3-compatible object storage server for storing unstructured data such as backups, images, and logs. It targets developers and operators who need self-hosted object storage. It is deployed via Docker, Kubernetes, or binaries.
- Fully S3-compatible API
- High throughput and erasure coding
- Cloud-native and Kubernetes ready
- Web console included
Ceph vs MinIO: key differences
The biggest difference is maintenance: MinIO's repository is archived and no longer developed, while Ceph is actively maintained. Ceph is written in C++, while MinIO is built with Go. Licensing differs — LGPL-2.1 for Ceph versus AGPL-3.0 for MinIO. MinIO is the lighter option, starting around 256 MB of RAM against 4,096 MB for Ceph. Ceph is the more established project (first released 2006), while MinIO arrived in 2015. MinIO has the considerably larger community, at 61,355 GitHub stars versus 17,069.
