Abstract : This document describes StratusLab's plans for exploitation and sustainability be- yond the project lifetime. The plans cover commercial exploitation, primarily through commercial integration and support; and non-commercial exploitation, through use in national and international research e-infrastructures: for operating grid resources on private clouds, and for running research-oriented community clouds. In addition, we plan exploitation through partner projects such as EGI and through training and future research. Plans are in place to ensure the sustainability of the critical infrastructures used by the project partners, users and collaborating projects. Similarly, the software outputs of the project have been identified and a plan for the future development of each has been created. These plans include the formation of an open-source StratusLab community, identifying key partners to continue development of specific components, identifying funding options (public, private and community contributions) for continued development and engaging with collaborating projects to ensure that they will contribute to the maintenance and development of the components that they use.
