C2@home - A Novel User-Side Cloud-of-Clouds Management Architecture

Today, the main limit for an efficient exploitation of resources owned by one or more IaaS environments is not technical, but structural: users and providers have two different views that rarely are really integrated. Cloud users have a deep knowledge about their workflows, but they don´t have any details about the real state of the IaaS physical resources. Cloud providers have the opposite problem: they know only the state of the offered resources but ignore the structure and time evolution of the user´s workflows that will run on them. Such a lack of common shared knowledge hardly limits the opportunity to optimise the performance of both sides. To fill this gap of integration, this paper proposes C²@home, an autonomic user-side management system designed to drive and optimise the deployment of workflows on Cloud of Cloud environments. Experiments demonstrate that the aggregation of information about workflows´ structure and evolution and actual data on hardware utilisation allow user to optimise the workflows performance.
