Open-Source & Self-Hosted Alternatives to Amazon S3 & Google Cloud Storage
Hyperscaler object storage services charging compounding monthly fees for storage, API requests, and aggressive bandwidth egress.
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.
