# Storage and Origin Architecture

Your origin decides how much a CDN can save you. A poorly shielded bucket still pays egress on every cache miss, while a well-designed origin keeps miss traffic low and predictable. This section is for infrastructure engineers, storage and backup teams, video platform architects and CTOs choosing where content should live.

Articles compare Amazon S3 with S3-compatible object storage such as Cloudflare R2, Wasabi, Backblaze B2 and MinIO, explain origin shielding and tiered caching, cover lifecycle and archive tiers, and look at NAS and SAN setups for media libraries. You will also find setup guides for using a bucket as a CDN origin and the cost math of reads, writes and egress. For bandwidth billing, continue in [cloud costs and egress](https://blog.blazingcdn.com/cloud-costs-egress?hsLang=en).
