Eliminating AWS S3 Egress Fees: Architecting Multi-Node MinIO and Ceph Object Storage
How to escape AWS S3 egress taxes by architecting self-hosted, distributed MinIO and Ceph object storage clusters with 100% S3 API compatibility.
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.

Frequently Asked Questions
How much can you save by self-hosting MinIO instead of AWS S3?
AWS charges up to $0.09/GB for data egress. Self-hosting MinIO on bare-metal eliminates egress fees entirely, saving thousands per month for data-heavy apps.
Is MinIO compatible with AWS S3 SDKs?
Yes, MinIO provides 100% S3 API compatibility and works seamlessly with AWS SDKs in Python (boto3), Node.js, and Go by changing the endpoint URL.
