Amazon web services (AWS) launched a new service called Amazon Glacier. You can use this service for archiving mission-critical data and backups in a reliable way in an enterprise IT or for personal usage. This service cost as low as $0.01 (one US penny, one one-hundredth of a dollar) per Gigabyte, per month. You can store a lot of data in various geographically distinct facilities and verifying hardware or data integrity, irrespective of the length of your retention periods. The first thing comes to mind is, the Glacier would be a good place for a backup off family photos and videos from my local 12TB nas.
Excellent news. This may come handy. In our data center we have a few servers for just two applications. These applications are just run for 2 or 3 days a month and then the rest of the time all servers in rack just sit idle. It is a waste of servers, time, energy and resources. This is a good use-cases for on-demand high I/O server(s), where I need low-latency and are an exceptionally good host for NoSQL databases such as MongoDB.
