FAQ — AWS & Vector Databases
What is the best AWS-native vector database?
Amazon OpenSearch Service is the most AWS-native option with deep integration into the AWS ecosystem. For a dedicated vector database on AWS, Pinecone and Qdrant Cloud both offer AWS deployments.
Can I run vector databases on Amazon EKS?
Yes. Milvus, Qdrant, Weaviate, and Vald all support Kubernetes deployment and work well on Amazon EKS with auto-scaling and persistent storage via EBS.
Which vector database works with AWS Bedrock?
OpenSearch, Pinecone, Redis, and pgvector (via Amazon Aurora) integrate with AWS Bedrock for RAG applications. OpenSearch has the deepest native integration.
