Zilliz Cloud

Zilliz Cloud is a fully managed vector database service (Web, API) built on Milvus for enterprises running production AI applications that need fast, scalable similarity search and retrieval for RAG.

Key capabilities include:

• Billion-scale vector search for large embedding collections, with support for IVF and graph-based indexing and similarity metrics such as Cosine, Euclidean (L2), and Inner Product
• Hybrid search across multimodal and sparse-dense scenarios (for example text, image, and audio), designed for modern RAG and multimodal retrieval
• Automatic performance optimization with AutoIndex plus the Cardinal search engine (listed as up to 10x higher query throughput and 3x faster index building)
• Enterprise security and connectivity, including SSO via Auth0 (Okta, GitHub, Google OAuth), RBAC, and AWS PrivateLink; BYOC deployment support is available

Pricing: Freemium with free tier available. Paid plans include Standard (From $0 - $99/month), Enterprise (From $155/month), and Business Critical (custom pricing).

Notable for combining managed Milvus operations (scaling and optimization) with Cardinal performance claims, and for adoption noted as 10,000+ enterprise users for use cases such as recommendations, anomaly detection, semantic search, and LLM/RAG applications.
