Last week Microsoft and Fujitsu announced a date for the very first implementation of the Windows Azure Appliance by Fujitsu. It is coming in August 2011.
Windows Azure Appliance is a container pre-configured with hundreds or thousands of machines running Windows Azure platform. Dell and HP are expected to follow Fujitsu soon. The longer vision is that smaller organizations will be given the platform to run their own Cloud.
It means the private Clouds are one step closer to reality. This should mitigate security concerns which is one of the biggest issues of hosting large data systems such as PI System.
