FortiFlex (formerly Flex-VM) is a subscription service to configure and manage VM usage entitlements. Subscribers can create multiple sets of a single VM entitlement that corresponds to a licensed virtual machine. Each entitlement contains a base VM and one service bundle. Usage entitlements require a unique token to be installed on every VM. Once the VM configurations are defined and VM entitlements are created in the FortiFlex portal, the VM instances can be deployed on the customer-managed platform in supported clouds and hypervisors.
