REDWOOD CITY, October 21, 2025 — Zilliz, the company behind Milvus, the world’s most widely adopted open-source vector database, today announced a significant update to Zilliz Cloud, its fully managed cloud service. The release introduces a rebuilt tiered storage system delivering 87% storage cost reduction, cross-region backups, and a new Business Critical plan designed for highly regulated industries—addressing critical enterprise needs for cost efficiency, advanced performance, and compliance readiness in sectors including healthcare, finance, and government.
“As organizations build increasingly complex AI applications, they need infrastructure that combines performance, predictability, and compliance,” said Charles Xie, Founder and CEO of Zilliz. “This release makes Zilliz Cloud not only faster and more affordable, but also better aligned with the real-world needs of enterprise AI teams.”
87% Storage Cost Reduction with Rebuilt Tiered Storage Architecture
Zilliz Cloud’s new Tiered Storage architecture reduces storage costs from $0.30 to $0.04 per GB per month—an 87% reduction—while improving query performance. Compute pricing is also reduced by 25%. For enterprises managing 10TB datasets, monthly storage costs drop from approximately $3,000 to $400.
The architecture stores entire datasets in object storage such as AWS S3, while using each cluster’s local SSD and memory as a high-performance cache. In production testing, the system achieves cache hit rates exceeding 90%, delivering object storage economics with in-memory responsiveness.
Business Critical Plan Addresses Regulatory Requirements
The new Business Critical plan extends Zilliz Cloud’s existing SOC 2 Type II, ISO 27001, and GDPR certifications with features designed for regulated industries:
- HIPAA readiness for healthcare and regulated workloads
- Global cluster deployments for data residency and low-latency access
- Multi-region replication and one-click failover for high availability
- Point-in-time recovery (PITR) for comprehensive data protection
Simplified Multi-Cloud Pricing
Starting January 1, 2026, Zilliz Cloud will standardize storage pricing at $0.04 per GB per month across AWS, Azure, and Google Cloud. The company will also introduce cross-region and cross-cloud data transfer capabilities, with fees passed through at provider cost without markup. Monthly free credits will cover baseline usage.
Additional enhancements include cross-region backup for dedicated clusters and index build level controls for Milvus 2.6.x clusters.
