Initial thoughts by Matt Domsch
- Use Reduced Redundancy Storage. All the content will be replicated easily.
- Use s3cmd sync to keep content in buckets in sync
- exclude ISOs
- exclude debuginfo? I think so.
- Use bucket policies to limit access to each region
- Need list of IP addresses for each region to populate MM. Would be nice if we could get that programmatically.
- bucket names s3-mirror-<region>.fedoraproject.org allow for CNAME s3-mirror.fedoraproject.org to s3.amazon.com in our DNS
| Region | Region Server | Bucket Name | CNAME |
| US Standard | s3-website-us-east-1.amazonaws.com | s3-mirror-us-east-1.fedoraproject.org | s3-mirror-us-east-1.fedoraproject.org CNAME s3-mirror-us-east-1.fedoraproject.org.s3-website-us-east-1q.amazonaws.com |
| US West (Oregon) Region | s3-website-us-west-2.amazonaws.com | ||
| US West (Northern California) Region | s3-website-us-west-1.amazonaws.com | ||
| EU (Ireland) Region | s3-website-eu-west-1.amazonaws.com | ||
| Asia Pacific (Singapore) Region | s3-website-ap-southeast-1.amazonaws.com | ||
| Asia Pacific (Tokyo) Region | s3-website-ap-northeast-1.amazonaws.com | ||
| South America (Sao Paulo) Region | s3-website-sa-east-1.amazonaws.com |
Torrents:
- if we upload ISOs, we get .torrent links "for free".
- no tracker stats :-(
- Can't group multiple files together into a single torrent
- we're paying for outbound bandwidth
- bucket policies keeping traffic in a single region means we need separate buckets for torrent content
Costs:
- none for all uploads
- none for intra-region requests
- 0.093/GB/month for data, 200GB = $30-40/month/region. 7 Regions.
- no way guess number of GET requests. $40 assumes 10M requests, while $30/month assumes 1M requests.
Total: ~$280/month, or $3360/yr
Open questions:
- do we sync to one region, then COPY to others? If so, what tool? That'll cost $ for bandwidth.
