... Taking into account knowledge engineering methodologies, it is possible to define a general model that is able to capture the features of Cloud resources, not only on the infrastructure level, but also on the platform and software ones. The description of the resources can be created using ontologies placed in every Control Service Layer of the Cloud-stack [23] Figure 4. The ontologies have been implemented using the Web Ontology Language (OWL). ...
Cloud Computing is a paradigm that applies a service model on infrastructures, platforms and software. In the last few years, this new idea has been showing its potentials and how, in the long run, it will affect Information Technology and the act of interfacing to computation and storage. This article introduces the FCFA project, a framework for an ontology-based resource life-cycle management and provisioning in a federated Cloud Computing infrastructure. Federated Clouds are presumably the first step toward a Cloud 2.0 scenario where different providers will be able to share their assets in order to create a free and open Cloud Computing marketplace. The contribution of this article is a redesign of a Cloud Computing infrastructure architecture from the ground-up, leveraging semantic web technologies and natively supporting a federated resource provisioning.
Cloud federation can be described through the concept of collaboration, where each organization has its own cloud(s) that deals with a different and independent domain but needs to work together with other organizations in order to fulfill a specific shared objective. According to this perspective, the federation is a collection of interacting clouds that collaborate with one another through the instantiation and management of shared subsets of resources (computation and storage resources as well as sensors and actuators). This idea could be profitably used in those scenarios in which different organizations have to share several resources (e.g., emergency response or disaster management scenario). On the other hand, when different independent organizations share their resources, several issues arise. One of them is related to interoperability problems. As a consequence, this work also introduces a framework for an ontology-based resource life cycle management and provisioning in a federated cloud infrastructure. Therefore, The main contributions of this work consists of redesigning a cloud infrastructure architecture from the ground up, leveraging Semantic Web and Semantic Web Service Technologies, and natively supporting a federated provisioning of any kind of resource. This paper exploits, as a motivating scenario, a flood emergency response system. Copyright © 2014 John Wiley & Sons, Ltd.
