FortiGate VM licenses are typically tiered by the number of virtual CPUs (vCPUs) they support. Sizing your Azure instance without matching your license will lead to wasted resources. License Model vCPU Range Typical Azure Instance Standard_D2s_v5 (throttled) VM-02S up to 2 vCPUs Standard_F2s_v2 or D2s_v5 VM-04S up to 4 vCPUs Standard_F4s_v2 or D4s_v5 VM-08S up to 8 vCPUs Standard_F8s_v2 or D8s_v5
Official Fortinet datasheets often list performance for large packets (1518 bytes). If your traffic is dominated by small packets (e.g., VoIP or DNS), you will need a larger VM size than the datasheet suggests to handle the higher packet-per-second (PPS) rate. 4. Deployment Strategies for Scalability
While FortiGate-VM can run on as little as 2 GB of RAM, features like Intrusion Prevention (IPS) and Antivirus are memory-intensive. For production, aim for at least 4 GB to 8 GB to ensure the system doesn't enter conserve mode .
Generally recommended for FortiGate because they offer a higher NIC-to-CPU ratio , which is essential for network-heavy workloads.
The number of interfaces you can attach is strictly limited by the VM size. A single FortiGate instance often requires at least four NICs (Management, External, Internal, and HA Sync).
If a single VM isn't enough, consider these advanced architectures: FortiGate VM on Microsoft Azure Data Sheet - Fortinet
When selecting your size in the Azure Marketplace, keep these three technical limits in mind:
