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

If you're looking for archival storage solutions, we recommend using the Amazon 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 [Amazon Glacier storage classes](https://www.amazonaws.cn/s3/storage-classes/glacier/).

Amazon Glacier (original standalone vault-based service) is no longer accepting new customers. Amazon Glacier is a standalone service with its own APIs that stores data in vaults and is distinct from Amazon S3 and the Amazon S3 Glacier storage classes. Your existing data will remain secure and accessible in Amazon Glacier indefinitely. No migration is required. For low-cost, long-term archival storage, Amazon recommends the [Amazon S3 Glacier storage classes](https://www.amazonaws.cn/s3/storage-classes/glacier/), which deliver a superior customer experience with S3 bucket-based APIs, full Amazon Web Services Region availability, lower costs, and Amazon service integration. If you want enhanced capabilities, consider migrating to Amazon S3 Glacier storage classes by using our [Amazon Solutions Guidance for transferring data from Amazon Glacier vaults to Amazon S3 Glacier storage classes](https://www.amazonaws.cn/solutions/guidance/data-transfer-from-amazon-s3-glacier-vaults-to-amazon-s3/).

# Internetwork Traffic Privacy
<a name="InternetworkTrafficPrivacy"></a>

Access to Amazon 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)](https://docs.amazonaws.cn/STS/latest/APIReference/Welcome.html) to generate temporary security credentials to sign requests.

## VPC Endpoints
<a name="GlacierAndEndpoints"></a>

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 Amazon Glacier does not support VPC endpoints directly, you can take advantage of Amazon Simple Storage Service (Amazon S3) VPC endpoints if you access Amazon Glacier as a storage tier integrated with Amazon S3. 

For more information about Amazon S3 lifecycle configuration and transitioning objects to the Amazon Glacier storage class, see [Object Lifecycle Management](https://docs.amazonaws.cn/AmazonS3/latest/userguide/object-lifecycle-mgmt.html) and [Transitioning Objects](https://docs.amazonaws.cn/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html) in the *Amazon Simple Storage Service User Guide*. For more information about VPC endpoints, see [VPC Endpoints](https://docs.amazonaws.cn/vpc/latest/userguide/vpc-endpoints.html) in the *Amazon VPC User Guide*.
