With AOS 7, DevOps and platform engineering teams can confidently run containerized microservices alongside traditional VMs — all on the same HCI fabric.

🔐 4. Automated Security Compliance: STIG, DISA & FIPS

Security is now integral and automated:

• Pre-built Security Profiles: Out-of-the-box support for DISA STIG and FIPS 140-2 compliance standards.

• Security Central Integration: Centrally audit and monitor security posture across clusters with real-time recommendations.

• Role-Based Access Control (RBAC): Enhanced role definitions and granular access auditing for compliance-sensitive environments.

• Cluster Hardening Automation: Run security playbooks that enforce CIS/NIST policies at scale with no downtime.

For federal, healthcare, and financial institutions, these features reduce audit preparation time and risk exposure.

🛠️ 5. 1-Click LCM and Predictive Upgrades

Lifecycle management continues to be a Nutanix strength — and AOS 7 makes it even more hands-free:

• One-Click Firmware & BIOS Upgrades: Upgrade storage controllers, NICs, and BIOS firmware without ever leaving Prism.

• Preflight Check Automation: Automated compatibility checks reduce upgrade risks and ensure component alignment.

• Rolling Cluster Upgrades: Non-disruptive, node-by-node updates ensure continuous availability.

• Integration with Foundation Central: Remote deployment and post-deployment updates for ROBO and edge sites from a single pane of glass.

Admins can now confidently schedule upgrades with minimal effort and no planned outages.

💾 6. SmartTiering: Intelligent Data Placement

AOS 7 introduces SmartTiering — an intelligent tiering engine that automatically classifies and moves data between SSDs and HDDs based on usage:

• Real-Time Heat Mapping: Tracks read/write activity at the block level and tags “hot” vs “cold” data.

• Tier Rebalancing Engine: Uses machine learning to optimize data placement without admin input.

• Policy-Based Tiering Rules: Define thresholds for tier transitions and retention periods.

Ideal for capacity planning and storage cost optimization, especially in environments with large-scale file workloads, backups, or archival data.

🌐 7. Enhanced Flow Networking & Topology Visibility

Prism Central in AOS 7 introduces deeper insights into virtual network traffic:

• VM-to-VM Traffic Flows: Visualize east-west traffic within a cluster, down to the virtual NIC level.

• Network Topology Maps: Get a graphical view of connected VMs, subnets, and VLAN segments.

• Policy Enforcement with Flow: Create microsegmentation policies that isolate apps or block lateral movement using Nutanix Flow Security.

Security and network teams gain visibility that was once only possible through third-party SDN tools — now native and built-in.

🤖 8. AI-Powered Insights with Prism Pro

Prism Pro continues to evolve as the smart brain of Nutanix infrastructure:

• Anomaly Detection: Uses machine learning to detect deviations from normal usage and alert admins.

• Capacity Forecasting: Predicts future compute and storage needs using actual growth patterns.

• What-If Planning: Run simulations to model impact of adding/removing nodes, changing workloads, or shifting VM placement.

• Advisor Integration: Get proactive health recommendations backed by telemetry and best practices from Nutanix Support.

This makes AOS 7 truly autonomous in resource planning and performance optimization.

📢 What’s New in AOS 7.0

In addition to core platform improvements, Nutanix AOS 7.0 introduces several brand-new features that significantly enhance security, resilience, disaster recovery, and platform scalability:
