The vMatrix: Server Switching

Today most Internet services are pre-assigned to servers statically, hence preventing us from doing real-time sharing of a pool of servers across as group of services with dynamic load. Fluidly copying services in and out of servers remains a challenge due to the many dependencies that such services have on software, hardware, and most importantly, people. In this paper we present a novel solution, which builds on top of the classic operating systems concept of a virtual machine monitor (VMM). A VMM allows us to encapsulate the state of the machine in a virtual machine file, which could then be activated on any real machine running the VMM software. This eliminates the software dependencies problem by allowing us to move the whole machine around including the operating system, libraries, and third party modules that the service depends on. It eliminates the hardware dependencies problem by allowing us to mimic the hardware that the service expects regardless of the real hardware of th...
