AWS Deprecates Two Dozen Services (Most of Which You’ve Never Heard Of)

AWS has deprecated approximately two dozen services in its quarterly cleanup, including 19 services entering maintenance mode, four being sunset, and one reaching end of support. Notable deprecations include Glacier APIs (the S3 storage class remains), S3 Object Lambda, CodeCatalyst, and Snowball Edge. Most deprecated services were commercial failures that never gained significant traction. Glacier's API removal is largely inconsequential since it's now an S3 storage class. CodeCatalyst failed to gain momentum after launch. Snowball Edge customers can continue using existing deployments but shouldn't plan new architectures around it. Many modernization tools are being consolidated into AWS Transform, while Systems Manager components are being wound down in favor of third-party alternatives.
