Best For
Billion-scale vector workloads with the widest selection of ANN index types — HNSW, IVF, DiskANN, SCANN, GPU indexes
Production RAG and agent memory at scale — serverless billing, generous free tier, and a managed experience with zero ops
Limitations
Self-hosted deployment is operationally complex (depends on etcd, MinIO, Pulsar/Kafka); no first-party MCP server yet; managed offering is through Zilliz, not Milvus directly
Cloud-only with no self-hosted option; vendor lock-in on proprietary index format; advanced features like dedicated read nodes add cost quickly at scale
