Internetwork Traffic Privacy - Amazon S3 Glacier

Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

This page is only for existing customers of the S3 Glacier service using Vaults and the original REST API from 2012.

If you're looking for archival storage solutions we suggest using the S3 Glacier storage classes in Amazon S3, S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, and S3 Glacier Deep Archive. To learn more about these storage options, see S3 Glacier storage classes and Long-term data storage using S3 Glacier storage classes in the Amazon S3 User Guide. These storage classes use the Amazon S3 API, are available in all regions, and can be managed within the Amazon S3 console. They offer features like Storage Cost Analysis, Storage Lens, advanced optional encryption features, and more.

Internetwork Traffic Privacy

Access to Amazon S3 Glacier via the network is through Amazon published APIs. Clients must support Transport Layer Security (TLS) 1.2. We recommend TLS 1.3 or later. Clients must also support cipher suites with Perfect Forward Secrecy (PFS), such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Diffie-Hellman Ephemeral (ECDHE). Most modern systems such as Java 7 and later support these modes. Additionally, you must sign requests using an access key ID and a secret access key that are associated with an IAM principal, or you can use the Amazon Security Token Service (Amazon STS) to generate temporary security credentials to sign requests.

VPC Endpoints

A virtual private cloud (VPC) endpoint enables you to privately connect your VPC to supported Amazon services and VPC endpoint services powered by Amazon PrivateLink without requiring an internet gateway, NAT device, VPN connection, or Amazon Direct Connect connection. Although S3 Glacier does not support VPC endpoints directly, you can take advantage of Amazon Simple Storage Service (Amazon S3) VPC endpoints if you access S3 Glacier as a storage tier integrated with Amazon S3.

For more information about Amazon S3 lifecycle configuration and transitioning objects to the S3 Glacier storage class, see Object Lifecycle Management and Transitioning Objects in the Amazon Simple Storage Service User Guide.
