Azure ((top)) | Fortigate Vm Sizing

Ensure your chosen Azure VM size permits the total number of NICs your network topology demands. For instance, many 2-vCPU instances only allow 2 NICs, forcing you to upgrade to a 4-vCPU instance purely for interface density. Licensing: BYOL vs. PAYG

Choosing the right FortiGate VM size in Azure is critical for balancing security performance with cloud costs. Because Azure instances have specific limits on CPU, RAM, and network throughput, your selection directly impacts how much traffic your firewall can inspect. Determining Your Throughput Requirements

For detailed configuration steps, refer to the FortiOS Azure Administration Guide .

This is a comprehensive guide and "paper-style" breakdown regarding FortiGate VM Sizing on Microsoft Azure. This document covers the selection methodology, specific SKU mappings, licensing implications, and architectural best practices.

Based on the factors mentioned earlier, here are some general guidelines for sizing a FortiGate VM in Azure: fortigate vm sizing azure

When sizing, you must look beyond just "CPU and RAM." Azure imposes limits that can throttle your firewall.

Any -as v4 sizes (they have less network acceleration) and older A-series VMs.

As organizations increasingly move their workloads to the cloud, ensuring the security and integrity of their infrastructure becomes a top priority. FortiGate, a leading network security appliance, offers a virtual machine (VM) solution that can be deployed in Azure to provide robust security features. However, to ensure optimal performance and efficiency, it's crucial to properly size the FortiGate VM for your Azure environment. In this article, we'll delve into the key considerations and best practices for FortiGate VM sizing in Azure.

To bridge the gap between your throughput needs and specific Azure VM instances, Fortinet provides an . This interactive tool can help you project performance and associated costs. Ensure your chosen Azure VM size permits the

FortiGate-VM supports several Azure instance families, each suited for different use cases: Instance Family Best Use Case Notable Limits High-performance firewalling, IPS, and SSL inspection.

By matching your throughput needs, inspection levels, and interface requirements to the correct compute-optimized Azure VM series, you can build a highly resilient cloud security architecture that performs reliably without inflating your monthly cloud bill.

High-throughput environments with millions of small packets (such as DNS or IoT traffic) strain the CPU much faster than large file transfers (like backups). Security Inspection Modes PAYG Choosing the right FortiGate VM size in

High-concurrency environments (e.g., large e-commerce backends or public-facing applications) demand substantial RAM. Every open network session consumes a specific allocation of system memory. If the VM runs out of memory, FortiOS enters , dropping or bypassing traffic to save the system from crashing. 3. Recommended Azure VM Series for FortiGate

Drastically reduces CPU overhead, lowers latency, and minimizes jitter.

: Azure limits the number of Network Interfaces (NICs) based on the VM size. D2/D2v2 : Supports only 2 NICs . D4/D4v2 : Supports up to 8 NICs .
