A feature activation system provides a mixed computing environment that includes a server and cloud computing. The hybrid model splits the execution of a communication feature between the cloud and the enterprise server installed at or with the enterprise. Service activation is linked to a portal that can communicate with either an intermediary system or directly with an entity executing computer programs in the cloud. When the customer desires to use a feature, the customer accesses the portal and activates the feature the enterprise desires. In the background, the portal instantiates a virtual machine, on any cloud platform, and then installs the feature with virtual machine on that cloud server. To execute feature, the enterprise server and the virtual machine exchange information between the server and the cloud and allow the feature to access the enterprise server or enterprise data. When the user has completed feature execution, the instance of the feature may be stopped and discarded and any data may be saved either at the enterprise or within the cloud.
