Low-cost vector storage and similarity search Partial match

Amazon S3 Vectors has no Azure storage-layer equivalent. The closest Azure service is Azure AI Search, a search engine with vector, hybrid, and keyword search. Azure Blob Storage doesn't offer vector indexes.

  • Model. S3 Vectors is storage with built-in similarity queries, billed per use with no cluster. AI Search is a provisioned search service (billed per search unit) with much richer querying, including hybrid search, semantic ranking, filters, and agentic retrieval.
  • Latency. S3 Vectors favors cost over speed (subsecond for infrequent queries, as low as about 100 ms for frequent ones). AI Search is built for interactive search latency.
  • Integration. S3 Vectors plugs into Bedrock Knowledge Bases and can serve as a lower-cost tier for OpenSearch. AI Search plugs into Microsoft Foundry.
