A RunningOps host is a machine in your own network that runs tests for your RunningOps organisation, either a Docker machine for web runs or a Mac or Linux machine with phones on USB, connected through an outbound tunnel with no inbound port.
With the RunningOps host in the network option under Private networks (VPN), TestingOps pins a project's runs to that host, and those runs never fall back to the shared cloud pool.
The RunningOps host option uses no VPN client and no VPN sign-in, because the host is already inside the network.
Own hosts are part of the Enterprise package.
