A new whitepaper by David Chappell looks at how Windows HPC Server and the Windows Azure cloud work together on computationally intensive workloads. Citing the problems of security, data movement, and lack of ISV adoption, Chappell contends that most organizations won’t be able to rely solely on the HPC cloud as things sit today.
While the rise of cloud computing will surely have a big impact on the HPC world, the reality is that on-premises HPC clusters aren’t going away. Instead, providing a way to combine the two approaches—cluster and cloud—makes sense. This is exactly what Microsoft has done with Windows HPC Server and Windows Azure, supporting all three possible combinations: applications that run entirely in an on-premises cluster, applications that run entirely in the cloud, and applications that are spread across both cluster and cloud.
Chappell has written a number of related whitepapers recently such as Introducing the Windows Azure Platform.
