Comparisons anchored on Ceph, the unified block, file and object storage system.
Unified block, file and object storage on RADOS against a lighter blob store tuned for many small files with an S3 gateway. Weighs operational complexity, which workloads each fits, release support dates and SeaweedFS Enterprise features.
Whether to deploy Ceph with cephadm on Linux hosts or with the Rook operator inside Kubernetes. Covers the two methods the Ceph project recommends, what each manages through the cluster lifecycle, Rook's option to connect Kubernetes to an existing external Ceph cluster, and which teams each fits.
Unified block, file and object storage against S3-only object storage, with a status change that decides many cases: the MinIO community repository is archived and source-only, with AIStor as the commercial path. Covers licensing, architecture, operations and migration options.
Three self-hosted S3-compatible storage options compared after MinIO archived its community edition: maintenance status, licenses, architecture, scaling, operating effort and which to choose for new and existing deployments.
Persistent storage for Kubernetes: Ceph through Rook with block, file and object storage, against Longhorn's CNCF Incubating per-volume replicated block storage, on hardware needs, performance, backups to S3 or NFS, operations and team skills.
Ceph against GlusterFS for teams still running Gluster or weighing it: architecture, block, file and object interfaces, community activity and the end of Red Hat Gluster Storage in 2024, and how to plan a move to Ceph.
