Today we announced that RightScale acquired Scotland-based ShopForCloud, a free cloud cost forecasting website, and renamed it PlanForCloud. The website makes it easy to budget for your future cloud costs by giving you a set of tools to model your deployments and your usage patterns and automatically calculate costs across a variety of clouds.  PlanForCloud currently includes support for Amazon Web Services, Google Compute Engine, Rackspace and Microsoft Windows Azure with more clouds coming soon.
