If utilizing Azure Load Balancers to distribute traffic across multiple Active FortiGate VMs, you can size individual instances smaller (e.g., two Standard_F4sv2 instances instead of one Standard_F8sv2 ). However, ensure that if a single node fails, the surviving node has sufficient capacity to handle the failed node's traffic without hitting Azure network or CPU thresholds. 5. Performance Optimization Techniques
If your traffic needs change, you can resize the VM without losing configuration: Stop the FortiGate VM within the Azure Portal. Navigate to in the VM menu.
Sizing approach (practical steps)
In 2026, with the increasing complexity of cloud workloads, proper sizing involves analyzing throughput, network connectivity requirements, and the specific security features enabled. This guide covers how to size your FortiGate VM in Azure for optimal performance. 1. Key Factors for FortiGate VM Sizing in Azure

Post-deployment validation prevents production outages. Monitor your FortiGate VM using both Azure Monitor and FortiOS Diagnostic CLI commands. If utilizing Azure Load Balancers to distribute traffic
