What it really isZilliz Cloud — fully managed vector database (Milvus-as-a-service) for AI similarity search and retrieval.
Our takeZilliz Cloud is the enterprise managed layer built on top of open-source Milvus — the dominant vector database for AI workloads.
Zilliz offers a free tier with 5 GB storage and 100 CU-hours, then usage-based Serverless billing at $0.096/CU-hour, with Dedicated clusters starting around $70/month. Developer & Technical categorization is correct.
Why we rate itMilvus is the leading open-source vector DB; Zilliz Cloud removes all operational burden while maintaining full SDK compatibility — the natural managed choice for Milvus users.
The catchDedicated cluster costs scale quickly at high query volumes; GPU-accelerated search ($0.35–$1.20/GPU-CU-hr) adds up fast for compute-intensive workloads.

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: free-tier cluster spins up in minutes; Milvus SDK documentation is extensive and mature.
  2. Scale breakpoint
    At 10M+ vectors with sustained query traffic, Dedicated cluster costs reach $250–$500/month.
  3. Walled garden
    Low: fully compatible with open-source Milvus SDK; data can be exported and self-hosted at any time.
