High-performance instances (e.g., Standard_F2 , Standard_F4 ) are often preferred for firewall workloads because they offer a high CPU-to-NIC ratio and strong compute power for packet inspection.
Not all Azure VM sizes are equal. FortiGate is CPU-intensive (especially for VPN and SSL inspection). Memory is less critical (minimum 4-8 GB required per Fortinet, but Azure often provides more). fortigate vm sizing azure
This article breaks down how to correctly size a FortiGate-VM in Azure based on throughput, features, and workload type. High-performance instances (e
Ideal for high-throughput firewalling and IPsec VPNs. The Fsv2-series is frequently recommended for its high CPU-to-NIC ratio, which is crucial for complex HA (High Availability) setups requiring multiple interfaces. Memory is less critical (minimum 4-8 GB required
FortiGate-VM performance in Azure is primarily determined by three factors: vCPU count, RAM, and the specific Azure VM family architecture. vCPU Scaling
