In 2026, AWS extended Amazon S3 Vectors to its GovCloud (US-East and US-West) regions. This service provides purpose-built vector storage designed to support AI applications such as inference, retrieval-augmented generation, and semantic search at billion-vector scale. S3 Vectors offers APIs to store, access, and query vectors with the elasticity and durability expected from Amazon S3, eliminating the need for custom infrastructure provisioning.

This addition enables government and regulated sector customers to leverage scalable vector data storage compliant with GovCloud requirements, facilitating AI workloads that rely on large volume vector searches and similarity computations from secure cloud environments.
