It is possible to run the entire training platform "in the cloud" for remote training. This uses remote access via the "WAN" interface only.

In order to perform acceptably, the platform needs to support running KVM virtual machines, either on "bare metal" dedicated server hardware, or via KVM nested virtualization.

See remote access for configuration details for allowing inbound access from the Internet. When running gns3setup, select none as the LAN interface, and the normal interface as WAN.

The rest of this section collects some information about cloud providers that we have tested.
