Ceph
Pros
- + Unified object, block, and file storage from one self-healing cluster with no single point of failure
- + Free and open source (LGPL 2.1/3.0) under Linux Foundation governance
- + Proven at very large scale — CERN, OVH, DigitalOcean run production deployments
- + S3-compatible object API (RGW), erasure coding, replication, snapshots and clones built in
- + Strong Kubernetes story (Rook, Ceph CSI) and modern ops tooling (cephadm, dashboard, Prometheus)
Cons
- - Steep learning curve; incident response and tuning require real storage expertise
- - Practical minimum is a multi-node cluster (3+ monitors, ~4 GiB RAM per OSD, 10 Gb/s networking)
- - Total cost of ownership dominated by hardware and operations, not licenses
- - Vendor ecosystem in flux (SUSE exited Ceph-based products from 2021)
Cloudflare R2
Pros
- + Zero egress fees on all storage classes — no data transfer bill at all
- + Standing free tier: 10 GB-month storage, 1M Class A and 10M Class B ops monthly
- + S3-compatible API works with existing SDKs and migration tooling
- + Published durability (11 nines) and a 99.9% monthly uptime SLA with credits
- + Binds directly to Workers, Pages and public buckets with no cross-product egress
Cons
- - S3 feature surface is thinner — no replication topology, simpler lifecycle tooling
- - Class A operations at $4.50/million make write-heavy workloads pricier than storage-only math
- - Infrequent Access has a 30-day minimum storage duration and retrieval fees
- - Real lock-in sits in Workers-based processing around buckets, not the storage itself
- - Not suited to analytics-style scans or small-object high-churn data
