A processor-implemented method, system, and/or computer program product deploys software images onto a computing system. A first computing machine is instantiated from a software image onto a computing system. The first computing machine has a first old access identifier, and is initially connected to a second computing machine in the computing system via a second old access identifier for the second computing machine. The second computing machine is reconfigured to have a new access identifier by: retrieving the new access identifier for said second computing machine, and associating the new access identifier with the second old access identifier; and redirecting each outbound communication, from the first old access identifier to the second old access identifier, to the new access identifier of the second computing machine.
