A whole ‘nuther level of high availability – Guest Clustering: 20+ Days of Server Virtualization (Part 14)

You can try out guest clustering by downloading the Windows Server 2012 evaluation Did you know that virtual machines can also be clustered? 


Yep.  We call it “guest clustering”, where a cluster of application-hosting computers, sharing storage, are actually virtual machines.  In this way we provide a “whole ‘nuther level of high availability” in the fact that if an application can benefit from and take advantage of being cluster-aware, then we can support that availability even while the application is running on virtual machines. 

In part 14 of our “20+ Days of Server Virtualization” series, Keith Mayer describes the benefits and operations of virtual machine guest clustering in great detail, as well as some of the improvements to Hyper-V in Windows Server 2012 that make it even more powerful.
