Is Server Virtualization The New Clustering?
December 22, 2010 No CommentsVirtualization has become the new computing cluster. Clustering–the ability to have two or more computers operate in lockstep for highly available systems–has been around since almost the earliest PC and mainframe days. But a new take on clustering is emerging that leverages virtualization tools and is becoming more appealing, particularly as enterprise IT shops gain more experience using virtual servers and as virtualization vendors add more high-availability features to their products. Virtualization, along with cloud computing, is becoming the new way to provide redundant services, and as such is making it more affordable and within the reach of businesses without a lot of IT expertise.
