| Mistake | Consequence | Fix | | :--- | :--- | :--- | | Using B-series VMs | Dropped packets after CPU credit exhaustion | Switch to D or F series. | | Pairing 8‑vCPU VM with VM04 license | Wasted Azure cost, no performance gain | Match vCPUs to license tier. | | Forgetting SSL inspection overhead | Throughput drops 80% unexpectedly | Double vCPUs from raw baseline. | | Deploying single VM for critical path | No HA, Azure host maintenance causes outage | A-P pair + Azure LB or FortiGate FGCP. |
When sizing a FortiGate VM in Azure, consider the following factors: fortigate vm sizing azure
