Amazon launched its latest cloud storage service this week, Glacier. It aims to provide an “extremely low-cost storage service that provides secure and durable storage for data archiving and backup” for enterprise users. Costs can be as low as $0.01 for each gigabyte per month thanks to the fact that it “is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable”. Amazon also adds that companies usually over charges for their backup solutions, with high upfront costs not including the operational costs (power, facilities, staffing and maintenance).
Amazon Glacier on the other hand does not charge upfront fees, instead, “You pay only for what you need” with low monthly rates. AWS (Amazon Web Services) also takes care of all maintenance to ensure the data is secure and operational. One small drawback is that data retrieval could take between 3.5 to 4.5 hours if necessary.
Using Glacier is fairly simple, just go to the AWS Management Console. From there, begin to store your data into archives (single file or a group of multiple files). These are then organised in vaults with access controlled using the AWS Identity and Access Management service. The service uses SSL to transfer data while stored information is encrypted using Advanced Encryption Standard (AES) 256.
