Two dominant trends of the Internet are the increasing importance of multimedia traffic, not only in the form of streaming videos but also for interactive communications, and the use of cloud technology to deploy services. In this paper, we look at the intersection of these trends and expose a number of considerations to help with the deployment of multimedia functions for interactive, mobile-adaptive and time-constrained applications in the cloud. We show how virtual servers can be CPU or bandwidth constrained and how to use them effectively.
