Concerns have been raised about how expensive Glacier gets if you need to recover a lot of files in a short time period. http://www.wired.com/wiredenterprise/2012/08/glacier/ On 1/10/13 5:56 PM, Roy Tennant wrote: > I'd also take a look at Amazon Glacier.

All of the images from in our online collections database are being served straight from S3, which diverts the load from our public web server. When we launch zoomable images later this year, all of the tiles will also be generated locally in the DAM and then served to the public via the mirrored copy in S3. >> >> The current pricing is around $0.08/GB/month for 1-50 TB, which I think is fairly reasonable for what we're getting.
