Zilliz Cloud Update: Smarter Autoscaling for Cost Savings, Stronger Compliance with Audit Logs, and More
AI is moving fast from proof-of-concept to production—but scaling brings rising costs, strict compliance demands, and operational complexity. Today, we’re excited to launch the latest update of Zilliz Cloud, introducing smarter autoscaling with scale-down, enterprise-grade audit logging, an enhanced SSO experience, and Milvus 2.6 in Private Preview. Together, these advancements make Zilliz Cloud more cost-efficient, more performant, compliant, and enterprise-ready.
Smarter Autoscaling for Automatic Cost Optimization
Vector search workloads rarely run at full speed all the time. A recommendation engine may spike with thousands of queries during business hours but sit nearly idle overnight. An e-commerce search might surge during promotions and run quietly the rest of the week.
Zilliz Cloud has already made scaling up automatic, ensuring performance during traffic spikes. With this release, scaling down is now automatic too—closing the loop on cost optimization. Instead of tuning thresholds or guessing when to adjust, you simply set a minimum and maximum CU range, and Zilliz Cloud optimizes capacity in real time. That means you get:
Lower costs – resources scale down automatically when demand falls.
Consistent performance – resources scale up instantly when demand surges.
Simpler operations – no more manual threshold management or constant reconfiguration.
In short, autoscaling now ensures you always have the right resources at the right time—without wasted spend or performance risks.
Audit Log GA: Enterprise Security and Compliance Made Simple
While cost optimization is one challenge, compliance is another top priority for enterprises. Zilliz Cloud already delivers robust security, and with the added Audit Log, enterprises gain more granular visibility into how their clusters are used.
Launched in Private Preview this March, Audit Log quickly proved its value. Customers highlighted how it helped them track user activity, troubleshoot incidents, and provide clear records for audits. Now, Audit Log is generally available across all AWS, GCP, and Azure-hosted clusters.
With Zilliz Cloud Audit Logs, enterprise users gain:
Detailed visibility into queries, searches, data operations, connection events, and user/role changes.
Enhanced security by detecting unusual patterns and monitoring sensitive operations.
Simplified compliance through comprehensive audit trails that support governance and regulatory requirements.
Faster troubleshooting by linking operational issues directly to activity history.
Note: Audit Logging is only available for clusters on the Dedicated-Enterprise plan tier or higher. If you’re on another plan, you can easily upgrade to enable this capability and take advantage of the enterprise-level support and service quality it provides.

Enhanced SSO Experience: Streamlined Enterprise Identity Management
For enterprises, unified identity management is the foundation for secure and compliant cloud deployment. Zilliz Cloud has long supported Single Sign-On (SSO), helping customers integrate with their existing identity providers. With this release, we’ve made the configuration process clearer, more reliable, and easier to follow.
The updated flow now includes:
IdP-Specific Flows – Step-by-step guidance for Okta (OIDC, SAML 2.0), Microsoft Entra (SAML 2.0), and Google Workspace (SAML 2.0).
Smarter Validation – Field mapping hints and certificate checks reduce the risk of misconfiguration.
Visual Guidance – IdP-specific examples streamline setup without constant back-and-forth between Zilliz Cloud and admin consoles.
These improvements give administrators a smoother setup experience while strengthening enterprise identity management and reducing support overhead.

Milvus 2.6 Available in Zilliz Cloud Private Preview
As the fully managed service of Milvus, Zilliz Cloud always brings open-source innovation to a production-ready environment—and Milvus 2.6 represents one of the most significant upgrades yet.
Today, we’re excited to announce that Milvus 2.6 is now available on Zilliz Cloud in Private Preview. This release introduces breakthroughs in efficiency, search, and scalability, helping customers cut costs while powering more demanding AI workloads. Highlights include:
