Cost Model - AWS Storage Services Overview

Cost Model

The cost of an EC2 instance includes any local instance store volumes, if the instance type provides them. Although there is no additional charge for data storage on local instance store volumes, note that data transferred to and from Amazon EC2 instance store volumes from other Availability Zones or outside of an Amazon EC2 Region can incur data transfer charges; additional charges apply for use of any persistent storage, such as Amazon S3, Amazon S3 Glacier, Amazon EBS volumes, and Amazon EBS snapshots. You can find pricing information for Amazon EC2, Amazon EBS, and data transfer at the Amazon EC2 Pricing web page.
