Nowadays, virtualized platforms have become the most popular option to deploy complex enough services. The reason is that virtualization allows resource providers to increase resource utilization. Deployed services are expected to be always available, but these longrunning services are especially sensitive to suffer from software aging phenomenon. This term refers to an accumulation of errors, which usually causes resource exhaustion, and eventually makes the service hang/crash. To counteract this phenomenon, a preventive approach to fault management, called software rejuvenation has been proposed. In this paper, we propose a framework which provides transparent and predictive software rejuvenation to web services that suffer software aging on virtualized platforms, achieving high levels of availability. To exploit the provider resources, the framework also seeks to maximize the number of services running simultaneously on the platform, while guaranteeing the resources needed by each service.
