It’s no secret that a majority of enterprises are slow to adopt PaaS solutions and favor IaaS solutions instead. What is a well-kept secret is that these enterprises are building their own PaaS solutions on top of IaaS without even realizing it.

Public cloud IaaS providers are competing heavily on price. Watching Google, AWS, and Microsoft play the falling prices game is like watching a ping-pong match. It is just a matter of time before IBM’s SoftLayer matches the prices as well. Adrian Cockcroft wrote a great piece called The Real Story Behind the Cloud Price War, which is a must-read for those trying to understand the impact of the market’s feverish competition to be the lowest-cost provider. Here is an important nugget from Adrian’s article:

Yet, with XenApp running on Windows 2008 R2 memory limitations are of far less issue.

Hypervisor technology and performance has moved on considerably – what is the impact of that? What other services can virtualized XenApp drive?
