Resource sharing is an important aspect how cost savings in cloud computing are realized. This is especially important in multi-tenancy settings, where different tenants share the same resource. This paper presents an approach to merge two application topologies into one, while on the one hand preserving the functionality of both applications and on the other hand enabling sharing of similar components. Previous work has not addressed this due to the lack of ways to describe topologies of composite applications in a decomposed, formal, and machine-readable way. New standardization initiatives, such as TOSCA, provide a way to describe application topologies, which are also portable and manageable.
