: Double the VM resources (two VMs active). For A/A, you also need more throughput per VM.
: Ideal for high-throughput tasks like batch processing or high-performance web servers.
Accelerated Networking is mandatory for production FortiGate instances. It bypasses the Azure host virtualization data path, reducing latency, jitter, and CPU utilization. Ensure your selected Azure VM size supports this feature to achieve maximum throughput. Network Interface (NIC) Limits fortigate vm sizing azure
: A minimum of 8 GB RAM is recommended for standard operation. For advanced features like Unified Threat Management (UTM) or Zero Trust Network Access (ZTNA), at least 4 GB is strictly necessary.
FortiGate VM is a virtualized version of the FortiGate network security appliance, which provides a comprehensive range of security features, including firewall, intrusion prevention, antivirus, and more. The VM can be deployed on various platforms, including Azure, to provide security and protection for cloud-based infrastructure. : Double the VM resources (two VMs active)
A common pitfall is sizing a VM based purely on "Firewall Throughput." Enabling advanced security features introduces significant CPU overhead.
Ensure the VM size allows for enough attached networks to support your architectural segmentation design. Network Interface (NIC) Limits : A minimum of
Deploying a virtual appliance in the cloud requires a strict balance between security performance and infrastructure costs. Unlike physical firewalls with fixed hardware capacities, a Fortinet FortiGate Virtual Machine (VM) running in Microsoft Azure depends entirely on the underlying Azure virtual machine size for its CPU, memory, networking, and storage capabilities.
If your traffic requirements change, you can resize the FortiGate VM.
