In this paper, the authors analyze approaches for addressing sustainability in established IT-Governance frameworks. Such frameworks are considered to be a powerful tool for ensuring compliance and proper IT operation in modern organizations. The authors assume that – in the context of the seismic changes in IT provisioning and usage that current trends such as Cloud Computing and Hybrid Computing are causing – there are potentials in them to improve sustainability of organizations' operations at both IT and business level too. The analysis is conducted in a holistic way, taking into account organizational and process aspects, sustainability of resource usage, IT-related aspects, as well as incorporating the view of the overall IT-Governance. The presented case study within a mid-sized German enterprise provides a corroboration of the proposed approach by measures for both its feasibility and effectiveness.

Abstract. Service-oriented architecture (SOA) in the enterprise was one of the key enablers for cloud computing. Therefore, it can serve as a natural fit for bringing traditional IT governance approaches forward to the challenges of cloud governance. In this work we present an approach for mapping IT governance mindsets to the aspects of SOA governance. It allows an IT organisation the adaptation and the continuous usage of already established governance models during the adoption of cloud computing solutions. We also present an application case study where we demonstrate the feasibility of the approach in real-life scenarios in the context of an international telecommunication provider.

Enterprises today often strive to keep up with the paces of technological development. A particular case in point is the IT function where traditional governance approaches are often questioned by technology trends. Examples for such trends in the last ten years are the service-oriented architecture (SOA) and cloud computing. The introduction of SOA in the enterprise was one of the key enablers for cloud computing. Therefore, it can serve as a natural fit for bringing traditional IT governance approaches forward to the challenges of cloud governance. This article presents an approach for extending IT governance mindsets to the areas of SOA and cloud governance. It allows an IT organisation the adaptation and the continuous usage of already established governance knowledge and models during the adoption of cloud computing solutions. The authors also present an application case study where they demonstrate the feasibility of the approach in real-life scenarios in the context of an international telecommunication provider.
