Alternatives are not always the right move. Zilliz Cloud remains strong in these scenarios.
9 vector databases evaluated. Key factors: indexing speed, query latency, and integration with LLM frameworks.
Expert Take
Milvus works well when you need to run billion-scale vector similarity searches with low-latency performance. The friction starts when you attempt to self-host the open-source version, which lacks a built-in administration UI and requires complex Kubernetes configuration. Before buying, compare open-source Milvus vs Zilliz Cloud: the managed cloud version provides a user-friendly administration interface and tiered hot-cold storage.
