Andreas Kohne provides a well-founded insight into the fundamentals of cloud computing, cloud federations, and SLA-based VM scheduling. Furthermore, FederatedCloudSim is introduced as a flexible and extensible simulation framework for investigating various federation scenarios. Using this framework, different scheduling strategies are examined, and their impacts on SLA compliance and the finances of cloud service providers are thoroughly analyzed. The author, Andreas Kohne, has intensively engaged with the field of cloud computing in recent years, specializing in SLA-based federated cloud environments. He works at a large IT systems house in Dortmund and publishes technical books in the areas of IT management and business development.
