greater security, improved integration of collaboration, and overall

Who should use it ?
Anybody looking forward to migrate to private cloud or even looking for a personalized analysis of his requirements and whether it would be worth for him to move to private cloud can use this tool to perform an On-Demand & instant analysis.
The output is a solid projection of what the cloud will do for their
organization, including potential benefits like lower TCO, faster
provisioning of new capabilities, greater security, and improved
integration of collaboration and overall agility. But there are certain things you should be able to provision yourself - It could be one of your tailor made application or some application with very low usage and not worth hosting on a new platform.
So, This tools major focus is to give you a picture of "Your Money Vs The Value" and this tool does it pretty well but if you are quite serious about moving to Private Cloud, my recommendation would be to hire an experienced professional to design your architecture and help you with the migration.
