Zilliz Cloud

Zilliz Cloud is a fully managed vector database built on Milvus. It's aimed at engineering teams building retrieval-augmented generation (RAG) pipelines, semantic search applications, and other similarity-search workloads that need production-grade infrastructure without the burden of running a self-hosted vector database cluster.

Pricing

Zilliz Cloud starts at $0/month, with metered usage-based pricing beyond the free tier. Costs scale with vector storage and compute across performance-optimized, capacity-optimized, and tiered-storage options — no full tier ladder is itemized here since Zilliz Cloud's own pricing page couldn't be independently re-verified.

API and Compliance

Zilliz Cloud exposes an API, which fits its role as backend infrastructure meant to be wired directly into applications rather than something teams interact with mainly through a UI. On the compliance side, it holds SOC certification and is described as HIPAA-eligible with enhanced data privacy controls — a pairing that matters for teams in healthcare, finance, or other regulated spaces that need vector search over sensitive data while still satisfying audit requirements.

Feature Set

The feature list is weighted toward the operational realities of running vector search at scale, rather than the search algorithms themselves:

• Fully managed vector databases with core APIs, so there's no need to provision or patch the underlying Milvus infrastructure
• Built-in encryption for data in transit and at rest
• Backup, restore, and basic monitoring for operational continuity
• A 99.95% uptime SLA, giving teams a concrete availability commitment to build production dependencies on
• Audit logs, SAML 2.0-based SSO, and granular role-based access control (RBAC) for enterprise identity and access governance
• Multi-replica support and elastic scaling to absorb variable query load
• Private endpoint and VPC peering options for network isolation
• Global cluster support with disaster recovery, useful for teams operating across regions or needing failover
• Customer managed encryption keys (CMEK), putting key rotation and revocation directly in the customer's hands rather than leaving it solely to the provider
• HIPAA-eligible configuration with enhanced data privacy, as noted above
• Zero-copy access to external data, letting teams query data sources without first duplicating them into the vector store

Summary

The feature set and pricing structure together point to a platform built for production RAG and semantic search systems rather than hobbyist projects or prototypes — the kind of deployments where SLA guarantees, RBAC, SSO, and compliance eligibility stop being nice-to-haves and start being requirements. The hybrid pricing model — a $0 entry point layered over per-million-vector rates across three optimization tiers — means actual cost tracks workload size, so teams should estimate their expected vector volume and pick between the $63, $16, and $5 per-million-vector tiers based on their latency needs and cost tolerance, rather than treating the starting price as a proxy for ongoing spend. Between the API-first access model, SOC certification, and HIPAA eligibility, the service is clearly built for organizations that need both programmatic integration and a documented compliance story.
