Ceph for Public Cloud Workloads
summary
Claim: colocating a Ceph cluster next to public-cloud regions cuts multi‑year storage bills dramatically while keeping fast internet access and control. Concrete build: Dell R740xd2 with 4 NVMe + bcache, 3 management nodes (Juju/MAAS), 25G networking. Model details: 2.5 PB = ~$3.9M public cloud over 5 years vs ~$850k hardware plus colo/connectivity and modeled 10 full reads; config uses erasure coding 4+2 and reaches break‑even at ~9 months.
