1. A method for deploying software images onto a computing system, the method comprising: instantiating, by one or more processors, a first computing machine from a software image, wherein the first computing machine is instantiated onto a computing system, wherein the first computing machine has a first old access identifier, wherein the first computing machine is initially connected to a second computing machine in the computing system via a second old access identifier for the second computing machine, and wherein the second computing machine has been instantiated from the software image; reconfiguring, by one or more processors, the second computing machine to have a new access identifier, wherein said reconfiguring is achieved 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.
