Eliminating AWS S3 Egress Fees: Architecting Multi-Node MinIO and Ceph Object Storage

Storing data in AWS S3 is relatively cheap ($0.023/GB/month). But pulling your data out of S3—known as Data Egress—costs up to $0.09 per gigabyte. For AI companies training vision models, media platforms streaming video, or SaaS platforms serving user assets, S3 egress fees often exceed the cost of the actual servers.

By deploying distributed MinIO or Ceph RADOS Gateway on dedicated hardware, you get full S3 API compatibility, erasure coding redundancy, and zero bandwidth egress fees.
