Using Amazon Glacier AWS customers no longer need to worry about how to plan and manage their archiving infrastructure, unlimited archival storage is available to them with a familiar pay-as-you-go model, and with storage priced as low as 1 cent per GB it is extremely cost-effective. The service redundantly stores data in multiple facilities and on multiple devices within each facility, as Amazon Glacier is designed to provide average annual durability of 99.999999999% for each item stored.
In Amazon Glacier data is stored as archives, which are uploaded to Glacier and organized in vaults, which customers can control access to using the AWS Identity and Access Management (IAM) service. Data is retrieved by scheduling a job, which typically completes within 3 to 5 hours.
Amazon Glacier integrates seamlessly with other AWS services such as Amazon S3 and the different AWS Database services. What’s more, in the coming months, Amazon S3 will introduce an option that will allow customers to seamlessly move data between Amazon S3 and Amazon Glacier based on data lifecycle policies.
