—The energy costs of running computer systems are a growing concern: for large data centers, recent estimates put these costs higher than the cost of hardware itself. As a consequence, energy efficiency has become a pervasive theme for designing, deploying, and operating computer systems. This paper evaluates the energy trade-offs brought by data(More)
Dynamic provisioning systems change application capacity in order to use enough resources to accommodate current load. Rejuve-nation systems detect/forecast software failures and temporarily remove one or more components of the application in order to bring them to a clean state. Up to now, these systems have been developed unaware of one another. However,(More)
