Amazon Web Services Launches 'Glacier' Storage for One Penny
Amazon Web Services announced a new data storage service known as Glacier, which enables users to store data at a rate of a penny for each gigabyte stored per month.Amazon Web Services recently announced a new service known as Amazon Glacier, which enables users to store data at low cost-as low as 1 cent per gigabyte per month. As with all AWS services, you pay for what you use. There is no up-front fee; users simply pay for the storage they use, said AWS evangelist Jeff Barr in a blog post.
"With Glacier, you can store any amount of data with high durability at a cost that will allow you to get rid of your tape libraries and robots and all the operational complexity and overhead that have been part and parcel of data archiving for decades," Barr said.
Because the service is designed for long-term archival needs, not active use, it's understandable that the fees for retrieval will be high in comparison to the fees for storage to discourage the use of Glacier for general-purpose storage. It will also take three to five hours to prepare an archive for downloading, which will also deter misuse of the service. Presumably, Amazon powers off the hardware until it's needed. But the retrieval fees are confusing. According to Amazon's pricing chart, you can request up to 5 percent of the data stored in Glacier for free each month, but it's prorated by the day. The FAQ explains: "If on a given day you have 12 terabytes of data stored in Glacier, you can retrieve up to 20.5 gigabytes of data for free that day (12 terabytes x 5% / 30 days = 20.5 gigabytes, assuming it is a 30-day month)." Elsewhere in the FAQ it explains that this is about 0.17 percent a day ("5% / 30 days = 0.17% per day").Glacier is available now for use in the U.S.-East (N. Virginia), U.S.-West (N. California), U.S.-West (Oregon), Asia-Pacific (Tokyo) and EU-West (Ireland) regions. Users can access Glacier from the AWS Management Console or through the Glacier APIs. AWS also has added Glacier support to the AWS software development kits (SDKs) and provided Glacier documentation.
