Analyst firm The 451 Group has just released some very interesting findings about virtualization and availability in a recent report by Chief Analyst John Abbott. Some of the key take-aways include: • Virtual infrastructure can form the basis of fully automated availability processes. Availability becomes a default property of the virtual machine. • ‘Dial up’ levels of availability can be implemented, depending on the requirements of specific applications or departments. • If a system restore is required after a disaster, it’s usually much easier and much quicker to restore a virt...
