Last week Microsoft released the Window Azure Pack.
Now the name is slightly confusing as Azure for most of us is associated with Microsoft Public Cloud offering.
However the Windows Azure Pack is not a public cloud offering, quite the opposite it is an interface for your Private Cloud.
What Windows Azure Pack basically gives you is the same interface used by Windows Azure for you private cloud.
The Windows Azure Pack integrates with System Center and Windows Server to help provide a self-service portal for managing services such as websites, Virtual Machines, and Service Bus; a portal for administrators to manage resource clouds and a portal for multi-tenant services.
The Azure Pack is offered free to all Microsoft customers.
