Deployment choices are critical in determining the availability of applications running in a cloud. But choosing good deployment for various software application components into virtual machines is a challenging task because of potential sharing of components among applications and potential interference from multi-tenancy. This paper presents an approach for improving the availability guarantee of software applications by optimizing the availability, performance and monetary cost trade-offs of different deployment choices. The authors approach explicitly considers different classes of application requests during the decision process.
