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 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.

Famous quotes containing the word isolation:
“The one happiness is to shut one’s door upon a little room, with a table before one, and to create; to create life in that isolation from life.”
—Eleonora Duse (1859–1924)
