View Full Features →Milvus uses a distributed architecture with data replication across multiple query nodes and WAL-based durability through its log broker (Pulsar or Kafka). The coordinator services handle automatic failover and load balancing. Zilliz Cloud provides a fully managed experience with 99.9% uptime SLA, automatic backups, and cross-region replication. The system supports tunable consistency levels from strong to eventually consistent.
Yes, Milvus is open-source (Apache 2.0) and designed for self-hosting, though the distributed deployment has significant infrastructure requirements: etcd for metadata, MinIO or S3 for object storage, and Pulsar or Kafka for log streaming. The Milvus Operator simplifies Kubernetes deployment. Milvus Lite provides an embedded single-process mode for development and testing with API compatibility to the full distributed version.
Milvus offers multiple index types for different cost-performance trade-offs: DiskANN enables disk-based indexing for datasets that exceed memory, reducing infrastructure costs. GPU indexes accelerate queries on GPU-equipped hardware. Use partition-based data organization to limit search scope. On Zilliz Cloud, choose between performance-optimized and cost-optimized tiers based on latency requirements. Monitor resource usage through the built-in metrics exported to Prometheus.
Milvus's open-source nature and LF AI & Data Foundation governance reduce project abandonment risk. The PyMilvus SDK has a custom API that doesn't directly port to other vector databases. Key mitigation strategies include using framework abstractions, keeping embedding generation external, and leveraging the bulk insert/export utilities for data portability. The schema-defined collection model is relatively standard across vector databases.
AI builders and operators use Milvus to streamline their workflow.
