Benefits Of Amazon Glacier Over Traditional Approaches

The archives are organized in vaults, and you can control access to your vaults using the AWS IAM i.e. Identity and Access Management service. You can monitor the status of your Amazon Glacier jobs using the Amazon Glacier APIs, so could include the process within your applications.

This eliminates concerns about over-provisioning or under-provisioning these environments while correctly estimating the respective budgets tied to these projects.
