How Virtualization is Changing the Way We Think About Availability

Analyst firm The 451 Group has just released some very interesting findings about virtualization and availability

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 virtual machine than a physical machine.

• Virtualization infrastructure is already a core component in datacenter automation, unified computing (the bringing together of servers, storage and networking) and cloud computing. Availability services based on top of a virtualization layer will slot right into any of these longer-term initiatives that customers may be working toward.

• Industrial-strength storage networks, currently a best-practice requirement for virtual availability, will lose ground to alternatives, which are maturing.

• The worlds of high availability and disaster recovery are coming together as virtualization is added to the mix.

• Tools more friendly to end users are likely to emerge, reducing the load on enterprise IT support staff, but requiring sophisticated underlay technology.

The 451 Group hosted a webinar a few days ago on this topic, which is available to download for free here: http://www.451group.com/report_view/report_view.php?entity_id=58563
