Provider Cost Comparison (Ranked by Total Cost)
The Economics of Cloud Object Storage & Bandwidth
In modern cloud architecture, storing data is cheap, but moving data across internet boundaries is expensive. Understanding the interplay between raw disk capacity, HTTP API operations, and outbound egress bandwidth is the cornerstone of effective cloud FinOps. Choosing the right object storage provider can cut monthly cloud infrastructure spend by thousands of dollars.

Frequently Asked Questions
Why is AWS S3 egress bandwidth so expensive?
Amazon Web Services charges approximately $0.09 per GB for data transferred out of S3 to the public internet (after the initial 100 GB free tier). For high-traffic applications serving videos or large files, egress bandwidth often accounts for over 70% of the entire AWS bill, far surpassing the base storage cost.
How does Cloudflare R2 eliminate egress charges?
Cloudflare R2 is built natively on Cloudflare's global edge network. Cloudflare operates its own private backbone and peering relationships, allowing them to provide S3-compatible object storage with $0.00 egress fees regardless of how much data your users download.
What is the difference between Class A and Class B API operations?
Class A operations are mutation actions like `PUT`, `COPY`, `POST`, and `LIST`, typically billed around $0.05 per 10,000 requests on AWS and GCP. Class B operations are read actions like `GET` and `HEAD`, billed at lower rates (around $0.004 per 10,000 requests).
Is Wasabi really cheaper than AWS S3?
Yes. Wasabi charges a flat $6.99 per TB per month ($0.0069/GB) with zero egress fees and zero API request fees, making it over 80% cheaper than AWS S3 Standard for long-term storage and backup use cases.
