==Isolation and redundancy==
Isolation in these types of systems requires redundancy.  Should one part of the system fail, a redundant part will need to take its place.  Isolation must be failure proof for all types of failures whether they be [[Software bug|software]] or human caused failures.  One potential way to isolate parts of a system is using virtual machine monitors such as [[Xen]].  Virtual machine monitors allow many virtual machines to run on a physical machine and should there be a problem with one virtual machine it can be restarted without restarting the physical machine, or it can be stopped and another can take its place.
