► Heterogeneous Cloud environments need business-oriented autonomic service executions. ► A novel approach called Service-level agreement-based Service Virtualization. ► Built on three areas: agreement negotiation, brokering and service deployment. ► Principles of autonomic computing are used to cope with failures in Clouds. ► Validated in a simulation environment using a biochemical application.
