Instance type support
FortiGate-VM supports the following instance types on AWS. Supported instances in the AWS marketplace listing may change without notice and vary between bring your own license (BYOL) and on-demand models. See Order types. As of May 2018, C3 and M-series instances no longer appear as recommended instances.
When you run FortiGate-native active-passive HA, each FortiGate-VM instance requires four network interfaces (port 1 to port 4). For details, see Deploying FortiGate-VM active-passive HA on AWS within one zone.
For up-to-date information on each instance type, see the following links:

You can apply a smaller FortiGate-VM license if you are OK with consuming less CPU than is present on your instance. See Models.
To change your instance type to the recommended C5 instance type, ensure that ENA is enabled. Otherwise the instance does not boot up properly.
In the following example, after changing the instance type to C5, ENA is not enabled. The example shows changing the ENA support attribute to true:
$ aws ec2 describe-instances --instance-ids i-xxxxxxx --query "Reservations[].Instances[].EnaSupport"
[]
$ aws ec2 modify-instance-attribute --instance-id i-xxxxxxx --ena-support
$ aws ec2 describe-instances --instance-ids i-xxxxxxx --query "Reservations[].Instances[].EnaSupport"
[
true
]
The instance can now boot up as a C5 instance type.
FortiOS 6.4.3 and later versions support hot-adding vCPU and RAM. However, AWS may not support this. See Requirements for changing the instance type.
