Cloud Knowledge Modeling and Management

Almost all relevant infrastructures are using cloud‐based approaches to manage their resources, and have set up high‐availability solutions addressing different layers such as IaaS, PaaS, and SaaS. Several different vendors are covering different aspects and supporting different services natively for cloud solutions. Most of them provide specific products addressing only a limited number of features and services. On the other hand, the availability of a wide range of services is often the basis for selecting cloud solutions. Among the services that are requested is the ability to monitor, change, and move virtual machines and services in the same cloud for resource optimization and among different clouds to increase reliability and for migration purposes. To this end, the modeling and formalization of cloud models and information is becoming more relevant to the formalization of different aspects of a cloud at its different levels – IaaS, PaaS, SaaS – and to specific resources: hosts, virtual machines, networks, memory, storage, processes, services, applications, and so forth, and their relationships.
