Microsoft published a document offering insight into why Windows Azure and Windows HPC Server 2008 R2 are better together.
Author David Chappell, notes that Cloud computing is redefining the HPC paradigm.
"Why not take advantage of the massive data centers now available in the cloud? For example, Microsoft's Windows Azure provides on-demand access to lots of virtual machines (VMs) and acres of cheap storage, letting you pay only for the resources you use," he stated.
The potential benefits for HPC are obvious. Rather than relying solely on your own on-premises cluster, using the cloud gives you access to more compute power when you need it.
The point is that while buying new machines to expand the processing power of a HPC environment is always an option, with the generalization of Windows Azure worldwide, it might not be the only one, or the best.
This especially since some of the Windows HPC Server 2008 R2 workloads can simply be transitioned into the Cloud to Windows Azure. And in some scenarios it might in fact be more feasible for HPC customers to rely on Windows Azure than buy more server, setting up clusters, managing the new infrastructure, etc.
