Methods and apparatus consistent with the present disclosure may be used in environments where multiple different virtual sets of program instructions are executed by shared computing resources when different processes are performed in a virtual computing environment. Methods consistent with the present disclosure may be used to provide a form of redundancy that does not require two physically distinct computers. Such methods may use a set of physical hardware components and two or more sets of synchronized virtual gateway software. Architectural features of physical hardware components included in an apparatus consistent with the present disclosure may be abstracted from sets of virtual program code when one virtual software process backs up another virtual software process at the apparatus.
