Description We present an end-to-end framework for consumer-centric SLA management of virtualized database servers. The framework fa-cilitates adaptive and dynamic provisioning of the database tier of the software applications based on application-defined policies for satisfying their own SLA performance requirements, avoiding the cost of any SLA violation and controlling the monetary cost of the allocated computing resources. In this framework, the SLA of the consumer applications are declaratively defined in terms of goals which are subjected to a number of constraints that are specific to the application requirements. The framework continuously moni-tors the application-defined SLA and automatically triggers the ex-ecution of necessary corrective actions (scaling out/in the database tier) when required. The framework is database platform-agnostic, uses virtualization-based database replication mechanisms and re-quires zero source code changes of the cloud-hosted application.
