“…The bandwidth of this physical path of links needs to be shared between the two virtual datacenters; moreover, the actual physical bandwidth needs to be enough to accommodate the required bandwidths for the two virtual links (of course, the path links might also be currently used by other virtual datacenter embeddings). Implementing full-blown virtualization is incredibly difficult to achieve and is a vibrant area of research, with embedding just one aspect of virtualization (albeit a significant one); there are many other (more practical) aspects to consider too such as scalability, fault tolerance, security, performance isolation, and monitoring (the reader is referred to recent surveys [5,56,60] for detailed accounts of the current state of the art as regards datacenter virtualization).…”

We undertake the first formal analysis of the role of symmetry, interpreted broadly, in the design of server-centric datacenter networks. Although symmetry has been mentioned by other researchers, we explicitly relate it to various specific, structural, graph-theoretic properties of datacenter networks. Our analysis of symmetry is motivated by the need to ascertain the usefulness of a datacenter network as regards the support of network virtualization and prevalent communication patterns in multitenanted clouds. We argue that a number of structural concepts relating to symmetry from general interconnection networks, such as recursive-definability, the existence and dynamic construction of spanning trees, pancyclicity, and variations in Hamiltonicity, are appropriate topological metrics to use in this regard. In relation to symmetry, we highlight the relevance of algebraic properties and algebraic constructions within datacenter network design. Built upon our analysis of symmetry, we outline the first technique to embed guest datacenter networks in a host datacenter network that is specifically oriented towards server-centric datacenter networks. In short, we provide the graph-theoretic foundations for the design of server-centric datacenter networks so as to support network virtualization and communication patterns in cloud computing.

“…The constraint in Equation (15) ensures that the aggregate workload generated by all the SaaS providers is equal to the aggregate workload served by the IaaS providers, for all workload types k. The total workload serviced by IaaS provide i, is the total amount of workload received by it, summed across all the workload types. This condition is enforced through Equation (16).…”

“…Over the last few decades, there have been many improvements in the energy efficiency of cloud computing systems, starting from the server level to the level of a system of interconnected data centers [13][14][15]. Some of the commonly adopted strategies for achieving energy efficiency at individual server levels are, Dynamic Voltage Scaling (DVS), Dynamic Voltage Frequency Scaling (DVFS), etc.…”

Energy Aware Pricing in a Three-Tiered Cloud Service Market

Abstract:We consider a three-tiered cloud service market and propose an energy efficient pricing strategy in this market. Here, the end customers are served by the Software-as-a-Service (SaaS) providers, who implement customized services for their customers. To host these services, these SaaS providers, in turn, lease the infrastructure related resources from the Infrastructure-as-a-Service (IaaS) or Platform-as-a-Service (PaaS) providers. In this paper, we propose and evaluate a mechanism for pricing between SaaS providers and Iaas/PaaS providers and between SaaS providers and the end customers. The pricing scheme is designed in a way such that the integration of renewable energy is promoted, which is a very crucial aspect of energy efficiency. Thereafter, we propose a technique to strategically provide an improved Quality of Service (QoS) by deploying more resources than what is computed by the optimization procedure. This technique is based on the square root staffing law in queueing theory. We carry out numerical evaluations with real data traces on electricity price, renewable energy generation, workload, etc., in order to emulate the real dynamics of the cloud service market. We demonstrate that, under practical assumptions, the proposed technique can generate more profit for the service providers operating in the cloud service market.
