In this paper, the authors present three case studies as examples on how the previously mentioned challenges can be addressed and how the opportunities can be used to add value to systems running in cloud computing environments. The first two case studies are approaches on managing performance and dependability in cloud computing environments. Cloud computing promises a variety of opportunities but also brings up several challenges. The three case studies presented in the following are examples on how challenges in the field of capacity management, dependability, and scalability can be addressed and how opportunities of cloud computing can be leveraged to, e.g., maintain performance requirements or to increase dependability.
