What is Milvus?
Milvus is an open-source vector database created by Zilliz in 2019 and donated to the LF AI & Data Foundation in 2020, where it is now a graduated project. It is licensed under Apache 2.0 and offers multiple deployment modes: Milvus Lite (embedded, for local development), Standalone (single machine), and a distributed cluster mode for billion-vector scale. Zilliz also offers Zilliz Cloud as a fully managed alternative.

MilvusAI Platforms & Generative AIOpen-source vector database for billion-scale AI search
Key capabilities
- Multiple deployment modes: Lite, Standalone or distributed cluster, matching your scale.
- Billion-scale ANN search: Built for high-throughput approximate nearest-neighbor queries.
- Managed option: Zilliz Cloud for teams that don't want to operate a cluster.
Where Milvus fits
Vector database infrastructure for large-scale AI similarity search is the primary use case.
Positioning and limitations
Shortlist Milvus when you need to scale vector search beyond a single embedded database, with a growth path from local development (Milvus Lite) to a distributed production cluster or Zilliz's managed cloud.
Confirm which deployment mode matches your actual scale and compare the operational effort of self-hosting a cluster against Zilliz Cloud's usage-based pricing.
