AWS has introduced vector search in several of its managed database services, including OpenSearch, Bedrock, MemoryDB, Neptune, and Amazon Q, making it a comprehensive platform for vector search solutions.

Microsoft Azure offers vector search support across multiple database services, enabling developers to leverage vector search in cloud-native and enterprise scenarios.

Transwarp Hippo is an enterprise-grade, cloud-native distributed vector database designed for scalable vector operations, including similarity search and clustering, targeting massive datasets and real-time recommendation systems.

Cloudflare Vectorize is a managed vector database/indexing service integrated with Cloudflare Workers AI. It stores and searches high-dimensional vector embeddings (such as text embeddings) using configurable dimensions and distance metrics like cosine and euclidean, automatically handling index optimization and regeneration when new data is inserted.

Qdrant Enterprise Solutions provide enterprise‑grade deployments and support for the Qdrant vector database, including advanced security, high availability, SLAs, and integration services for large‑scale AI search and recommendation use cases.
