Systems, methods, and other embodiments associated with cloud computing cluster isolation with strong authentication and automatic configuration deployment are described. In one embodiment, a method includes, in response to receiving an authentication frame through the uncontrolled port, (i) extracting data from the authentication frame for performing authentication, and (ii) parsing the authentication frame to identify a piggybacked virtual network identifier that functions as an instruction to create an isolated connection. If the authentication was successful and the piggybacked virtual network identifier was identified, creating the isolated connection between the controlled port and a virtual network that is identified by the piggybacked virtual network identifier.
