HIPCAL : State of the Art of OS and Network Virtualization Solutions for Grids

Virtualization can be used in different cases, with different goals in mind. For instance, virtualization techniques can be used to optimize the efficient use of a set of resources (By load-balancing virtual machines on physical machines). It can also be used to transparently put in production a set of virtual machines, to reduce costs by sharing physical machines while still allowing the grow of the set of physical machines in a transparent way for applications, ease the development process without damaging the environment of the physical machine, etc.
