The editorial note

What to know about Backblaze B2

Backblaze B2 is an S3-compatible object storage service at a fraction of AWS S3's price — $0.006/GB storage (vs $0.023/GB for S3) and $0.01/GB egress (via Cloudflare partnership). It's widely used for backups, media storage, and as a CDN origin. The Cloudflare-Backblaze bandwidth alliance means egress from B2 to Cloudflare CDN is free, making it effectively zero-egress when serving through Cloudflare.
