AWS amazonglacier documentation change

Service: amazonglacier · 2025-10-10 · Documentation low

File: amazonglacier/latest/dev/getting-started-upload-archive-dotnet.md

Summary

Updated service name references from 'Glacier' to 'Amazon Glacier', added deprecation notice for original standalone Glacier service (no new customers after 2025), and emphasized migration guidance to S3 Glacier storage classes

Security assessment

Changes focus on branding consistency, service deprecation announcements, and migration recommendations. While the notice mentions existing data will 'remain secure', this is a general assurance rather than addressing a specific security vulnerability or introducing new security features. No encryption, access control, or vulnerability mitigation details were added/modified.

-# Upload an Archive to a Vault in Glacier by Using the AWS SDK for .NET
+Amazon Glacier (original standalone vault-based service) will no longer accept new customers starting December 15, 2025, with no impact to existing 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, AWS recommends the [Amazon S3 Glacier storage classes](https://aws.amazon.com/s3/storage-classes/glacier/), which deliver a superior customer experience with S3 bucket-based APIs, full AWS Region availability, lower costs, and AWS service integration. If you want enhanced capabilities, consider migrating to Amazon S3 Glacier storage classes by using our [AWS Solutions Guidance for transferring data from Amazon Glacier vaults to Amazon S3 Glacier storage classes](https://aws.amazon.com/solutions/guidance/data-transfer-from-amazon-s3-glacier-vaults-to-amazon-s3/).
