Services in the AWS GovCloud (US-West) Region

The following sections describe the differences between the AWS GovCloud (US-West) Region and the standard AWS Regions. They include links to documentation and describe the ITAR boundaries (where you can and can't enter or process ITAR-regulated data) for each service. ITAR-regulated data is permitted in most configuration data fields. However, some of the data fields, such as Amazon S3 bucket names or Amazon EC2 tags, cannot contain ITAR-regulated data. Also, some services, such as Amazon SNS, cannot process ITAR-regulated data at all.
