This paper will define a number of levels of abstracted cloud computing for vehicles. First, the transition from current architectures of dedicated hardware to basic dedicated virtualization of processes with hardware defined networks will be detailed using Commercial-of-the-Shelf (COTS) hardware and operating systems available now. Second, the transition to cloud-based processes with hardware defined networks will be detailed using the same hardware baseline. Third, the transition to software defined networks will be shown using the same hardware baseline. Once this new baseline of cloud based processing is detailed on existing hardware, the diffusion of the cloud onto an increased number of more SWaP-C optimized processing elements (specifically, ARM) will be shown. Each level of abstraction will be rated with a number of figures of merit and correlation to vehicle metrics / capabilities. A clear roadmap towards implementation will be shown, with defined phases to adapt and mature technologies to implement cloud computing in military vehicles.
