Abstract: The shift from enterprise computing to service- oriented and cloud computing is happening very rapidly. As the demand for higher value services increases there will be a greater need for service customization, automation for the provisioning and management of services, and the ability to offer services that satisfy non-functional requirements. This paper describes our research on a model-driven approach for packaging high value enterprise software for use as a service and on managing the service lifecycle of service instances in shared virtualized resource pools. Our approach tackles non-functional issues such as availability, security, scalability, flexibility, and performance. These are important for high value enterprise IT services. A study involving an SAP system demonstrates our progress. Our results show that a model-driven approach can be attractive to software providers that aim to support a large number of service instances.
