What it really is

Zilliz Cloud - the fully managed cloud version of the open-source Milvus vector database, for AI similarity search, RAG retrieval and embedding storage at scale.

Our take

It's the easiest way to run Milvus without ops: a permanent free tier (5 GB, 2.5M vCUs/mo), serverless pay-as-you-go ($4/M vCUs + $0.04/GB storage), or dedicated clusters (~$99-155+/mo) for predictable performance. Strong for production RAG/semantic search, with the trade-offs being usage-based billing complexity and dedicated clusters costing more than self-hosting.

Best for
Developers building RAG/semantic-search applications
Teams wanting managed Milvus without self-hosting ops
Production AI apps needing billion-scale vector search
Not good for
Tiny projects that fit in a simple pgvector setup
Teams wanting fully predictable flat monthly pricing
Non-technical users (it's a developer database)
Friction report
Time to value
Fast: sign up free, create a cluster, and insert/query vectors via SDK in minutes.
Scale breakpoint
Serverless costs vary with query volume; dedicated clusters jump to ~$99+/mo for predictable performance.
Walled garden
Low-to-moderate: Milvus is open-source portable, but managed features tie to Zilliz.
