Open-Source & Self-Hosted Alternatives to Amazon S3 & Google Cloud Storage
AWS S3 lists storage at $0.023/GB-month, but the real bill is egress: $0.09/GB out, plus $0.005 per 1,000 GET and $0.005 per 1,000 PUT requests. A single 10TB monthly export to a customer runs $900+ in transfer fees alone. Self-hosted S3-compatible stores (MinIO, Garage, SeaweedFS, Ceph) run on a €3.79–€55/month VPS or dedicated box with 1Gbps unmetered bandwidth and zero per-request fees. Same S3 API, same AWS CLI, same SDKs — your application code does not change.
Why Migrate Away from Amazon S3 & Google Cloud Storage?
Cloud storage providers like AWS S3 and GCS charge exorbitant egress bandwidth fees and high per-request PUT/GET fees. Self-hosting MinIO or Garage S3 turns standard NVMe/SSD storage or commodity hard drives into blazing-fast S3-compatible buckets with zero transfer fees, full AWS CLI/SDK compatibility, and enterprise encryption.
