Microsoft just annouced the public preview of its TCO calculator tool.
This tool will help you see if Azure will reduce or not the TCO of your Virtualization or Physical on-premises platform. It will give you a cost forcast on a 3 years period. This is a valuable tool for organisations planning to renew their on-premises infrastructure or a part of it.
This tool is a must for Cloud Architects, consultants or IT managers.
Give it a try, i will update the article with the feedback links.
