Recovery-oriented computing
Recovery-oriented computing (sometimes abbreviated to ROC) is a method constructed at Stanford University and the University of California, Berkeley for developing reliable Internet services. Its proponents seek to recognize computer bugs as inevitable, and then reduce their harmful effects. The National Science Foundation funds the project.
There are characteristics that set recovery oriented computing apart from all other failure handling techniques.
==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.
