The use of hybrid clouds enables companies to cover their demands of IT resources saving costs and gaining flexibility in the deployment of infrastructures by paying under demand these resources. However, considering a scenario with various services to be allocated in more than one cloud, it is necessary to find the distribution of services that minimizes the overall operating costs. This paper researches on the resource allocation methodology to be applied in a multi-cloud scenario based on the findings derived from the framework used for the FINESCE project. The purpose of this work is to define a methodology to assist on the hybrid cloud selection and configuration in the Smart Grid for both generic and highly-constrained scenarios in terms of latency and availability. Specifically, the presented method is aimed to determine which is the best cloud to allocate a resource by (1) optimizing the system with the information of the network and (2) minimizing the occurrence of collapsed or underused virtual machines. Also, to assess the performance of this method and any alternative proposals, a general set of metrics has been defined. These metrics have been refined taking into account the expertise of FINESCE partners in order to shape Smart Grid clouds and reduce the complexity of computation. Finally, using the data extracted from the FINESCE testbed, a decision tree is used to come up with the best resource allocation scheme.

This chapter analyzes the Hybrid Cloud computing model, a paradigm that combines on-premise Private Clouds with the resources of Public Clouds. This new model is not yet fully developed, and there is still a lot of work to be done before true multi-Cloud installations become mature enough to be used in production environments. A review of some of its limitations and the challenges that have to be faced is done in this chapter, and some common techniques to address the challenges studied are also included. It also presents a Hybrid Cloud architecture based on the OpenNebula Cloud toolkit, trying to overcome some of the challenges, and present some real-life experiences with this proposed architecture and Amazon EC2.

Big Picture

This essay explores a peculiarly Victorian solution to what was perceived, in the middle of the nineteenth century, as a peculiarly Victorian problem: the fragmentation and miscellaneousness of the modern world. Seeking to apprehend the multiplicity and chaos of contemporary social, intellectual, political, and economic life, and to furnish it with a coherence that was threatened by encroaching religious uncertainty, Victorian poets turned to the resources of genre as a means of accommodating the heterogeneity of the age. In particular, by devising ways of fusing the conventions of the traditional epic with those of the newly ascendant novel, poets hoped to appropriate for the novelistic complexity of modern, everyday life the dignifying and totalizing tendencies of the epic. The essay reevaluates the generic hybridity of Elizabeth Barrett Browning’s Aurora Leigh (1856) as an attempt to unite two distinct kinds of length—the microscopic, cumulative detail of the novel and the big-picture sweep of the epic—in order to capture the miscellaneousness of the age and, at the same time, to restore order and meaning to the disjointed experience of modernity.
