Amazon S3 Vectors, designed as the first cloud object storage with native vector support, offers efficient, scalable storage and querying of up to two billion vectors per index with low latency. It expands machine learning capabilities such as AI agents and semantic search, integrating with Amazon Bedrock to optimize costs for large vector datasets. The service is built for elasticity, durability, and availability akin to Amazon S3.
In March 2026, AWS announced growth to 31 regions including Africa, Asia Pacific, Europe, the Americas, and US West (N. California). The platform allows elastic scaling to 10,000 vector indexes per bucket and returns query results in milliseconds, supporting AI inference and retrieval-augmented generation workloads globally without additional infrastructure management.
