| Free tier | No published byte cap - 'covers the cost of Amazon S3 storage and data transfer for high-value cloud-optimized public datasets'. Registry datasets run to hundreds of TB; the programme as a whole is reported at 300+ PB. unit TB; metered on stored-bytes |
|---|---|
| Price | none stated |
| Limits |
2-year term from acceptance, auto-terminates, renewable only if AWS offers ('AWS may offer to extend your participation prior to the end of the 2-year term'); renewal review looks at usage metrics. Rolling review, ~2-week decision. Licence must be permissive (CC BY 4.0 recommended; CC BY-NC and BY-ND barred). Account must be dedicated to the dataset - no compute, no other services. 90-day wind-down with data retrieval after termination. |
| Binding | write-gated the write is a queue with a person or a rule in it, so the upload rate is set by somebody else |
| Identity | card (placeholder) inferred from the category 'iaas'; the source record states no identity cost, so this is a class assumption, not evidence |
| Egress | Free to the public - programme covers 'distribution costs such as egress and cross-region data fees'. Direct S3 HTTPS GETs, no requester-pays. |
| Per-object cap | not stated |
| Retention | 90-day wind-down with data retrieval after termination. (90 days) |
| Interface | s3-compatible, rclone, cli part of the text of Free tier, above |
| Tooling | Plain S3 API; rclone 's3' backend; AWS CLI; anonymous HTTPS GET for consumers. |
| Composes with | One dedicated AWS account per dataset, each uncapped. Multiple datasets = multiple applications. Dataset can then be re-served through Cloudflare in front of S3 for further egress cover. |
| Reliability | Production S3; no data loss. The failure mode is review: a dataset that stops looking 'high-value' or stops growing does not get renewed, and the bill reverts to you. |
