Modeling cloud knowledge can be the basis for enabling a large range of reasoning applications. The modeling of cloud knowledge bases includes ontologies for cloud model representation at the levels of IaaS, SaaS and PaaS with all details regarding cloud resources. Additional aspects related to service level agreements and business metrics are also modeled to allow reasoning regarding cloud reconfiguration and adaptation to different conditions. The present state of the art shows a number of solutions and standards addressing mainly the problem of cloud interoperability and thus intercloud federation. The most widespread applications areas are related to (i) facilitating interoperability among public and private clouds, (ii) verification and validation of cloud configuration, (iii) discovering and brokering of services and resources, (iv) computing cloud simulation, (v) reasoning and adapting cloud workload …
