What it is

Zilliz Cloud is a managed Milvus service for deploying and scaling vector search applications. It supports approximate nearest neighbor, filtered, hybrid, and full-text search. Teams can choose Free, Serverless, or Dedicated cluster deployments; Serverless clusters scale automatically to zero. During ingestion, the service can create vector embeddings from raw text using a configured embedding function.

Documented integrations include Prometheus, Datadog, AWS S3, Azure Blob Storage, Google Cloud Storage, and external model providers. Migration sources include Pinecone, Qdrant, Elasticsearch, and PostgreSQL. The service supports sparse vectors, metadata filtering, up to 32768 dimensions, and a range of index types, including FLAT, HNSW, DISKANN, and AUTOINDEX. SDKs are listed for Python, Java, Go, Node.js, and C++. The Free cluster costs nothing and includes 5 GB storage, 2.5M vCUs/month, and up to 5 collections. Dedicated and Serverless pricing is pay as you go; storage charges apply to stored data and backup files even when a cluster is stopped.
