You digitised it to be seen. Then access became the expensive part.
On metered storage, every view of a high-resolution image is an egress charge. The more your collection is used, the more it costs — so the success you wanted becomes the bill you fear.
Egress scales with how much you are used.
IIIF deep-zoom delivers many tiles per image. A single popular exhibition or a class assignment can move terabytes in a month. On per-GB egress, the most-loved part of the collection generates the biggest invoice.
You cannot budget a number you cannot predict.
Egress depends on traffic you do not control — a viral object, a linked syllabus, a scraper. A storage line that should be flat becomes a variable you reconcile every month and cannot forecast for the year.
Rationing access to manage a bill.
Teams throttle resolution, gate downloads, or cache aggressively — not for any preservation reason, but to keep egress down. The mission is open access; the pricing model quietly works against it.
10 TB stored. 5 TB delivered a month.
Same collection, same monthly IIIF and download traffic, three providers. Storage, the egress charged to serve it, and the all-in monthly cost.
| Provider | Storage 10 TB/mo | Egress 5 TB/mo | All-in /mo |
|---|---|---|---|
| AWS S3 Standard | $236 | $461 | $697 |
| Wasabi | $70 | $0 | $70 |
| Fil OneYou | $50 | $0 | $50 |
Scenario: 10 TB stored with 5 TB/month delivered to viewers (IIIF tiles, derivatives, downloads). AWS S3 Standard: ≈$236/mo storage ($0.023/GB) + 5 TB egress (5,120 GB × $0.09/GB) ≈ $461/mo ≈ $697/mo all-in. Wasabi: $6.99/TB = $70/mo, egress free within fair-use policy. Fil One: $4.99/TB = $50/mo, $0 egress. AWS and Wasabi rates from public US price cards, Q2 2026; figures indicative and rounded.
Serve as much as you like. The bill does not move.
$0 egress, always
Every IIIF tile request, every full-resolution download, every researcher who opens the collection reads at zero egress cost. Access volume never changes the bill.
Flat $4.99/TB
One rate for storage, nothing for delivery. The bill is your stored footprint times $4.99 — predictable enough to put in a budget line that holds for years.
IIIF server compatible
Serve directly from the standard S3 API that IIIF image servers like Cantaloupe and IIPImage already read. Point the tile source at Fil One — no re-architecture.
11 nines durability
Designed for 11 nines of durability. The master files behind every derivative and tile are held to an archival standard, not just a delivery cache.
One rate. $4.99/TB/month.
Storage. That is the whole bill. Egress is free, so a busy month and a quiet one cost exactly the same.
