Desktop Subscription Licenses
Desktop Subscription gets you access to use Autodesk software for a specified period of time, with the option to renew. Desktop Subscription offers (during the period of Subscription) benefits similar to a perpetual license with Maintenance Subscription, including basic support and, for most products, access to select Autodesk 360 cloud services. Other benefits include:

Cloud Service Subscription
Cloud Service Subscription can have a dramatic effect on the way you work. Now you can extend work from the desktop into the cloud, and simplify collaboration and streamline workflows through a broad selection of cloud-based services. Access to virtually infinite cloud computing power can significantly reduce visualization and simulation processing times, and frees up desktop resources for greater productivity and better results.
