Abstract
Software as a Service relies on ubiquitous network access which cannot be assured in mobile scenarios, where varying link quality and user movement impair the always connected property. We approach this challenge by utilizing movable service components between a remote cluster, cloud, or server and the client device using the service. To overcome connection disruptions, service components are moved to the client prior to connection loss and executed locally. Although the basic concept is a brute force approach, challenges arise due to best fitting service decomposition, accurate estimation of connection losses, and best trade-off between moving service components and the overhead caused by this proactive fault tolerance mechanism.
