Microsoft MSDN - Platforms

An MSDN Subscription is the best way to get exactly what you need for your next challenging project. MICROSOFT OPEN VALUE SUBSCRIPTION OPTION With the Subscription option, you pay a single price per desktop (five desktop minimum) to deploy Microsoft technology as the standard across your organization, just as with the Company-wide option. However, the Subscription option provides you with rights to run the software only during the term of the agreement with Microsoft (nonperpetual). SOFTWARE ASSURANCE Microsoft's Software Assurance gives you automatic access to new technology and provides productivity benefits, support, tools, and training to help deploy and use software efficiently. With Software Assurance, you receive access to new versions of licensed software released during the term of your agreement to deploy at your own pace. New Version Rights simplifies the procurement process and shortens the business process cycle, allowing you to reduce the costs associated with acquiring new version releases and immediately take advantage of the latest technology.
