Moving services to the cloud is a trend that has been going on for years now, with a constant increase in sophistication and complexity of such services. Today, even critical infrastructure operators are considering moving their services and data to the cloud; most prominently are telecommunication operators, who are calling for running their service as so-called virtual network services. These services are usually composed from a set of components, each with individual resilience and

Hence, the problem of describing the blueprint of how to build a service from its components, including the components' requirements, and how to derive an actual deployment from such a blueprint needs to be solved. In this paper, we present a first step in this direction. We have developed an information model to describe the resources and components of complex composite services, and a management system that maps such a description into a deployment model. We have based our prototype on OpenStack and have identified some shortcomings of it that need to be overcome to make an automated resilienceaware deployment and operation system reality.
