AWS instance types supported based on vCPU and memory
required for each VM-Series model.
The VM-Series firewalls support the following AWS instance
types— C3, C4, M3, M4.
You can deploy the VM-Series firewall on an AWS instance size
with more resources than the minimum VM-Series
System Requirements. If you choose a larger instance size
for the VM-Series firewall model, although the firewall only uses
the max vCPU cores and memory shown in table, it does take advantage
of the faster network performance that AWS provides.
