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:
“There is a very holy and a very terrible isolation for the conscience of every man who seeks to read the destiny in affairs for others as well as for himself, for a nation as well as for individuals. That privacy no man can intrude upon. That lonely search of the spirit for the right perhaps no man can assist.”
—Woodrow Wilson (1856–1924)
