document: Efficient application placement in a dynamic hosting platform Web hosting providers are increasingly looking into dynamic hosting to reduce costs and improve the performance of their platforms . Instead of provisioning fixed resources to each customer , dynamic hosting maintains a variable number of application instances to satisfy current demand . While existing research in this area has mostly focused on the algorithms that decide on the number and location of application instances , we address the problem of efficient enactment of these decisions once they are made . We propose a new approach to application placement and experimentally show that it dramatically reduces the cost of application placement , which in turn improves the end-to-end agility of the hosting platform in reacting to demand changes .
