Available in PDF, EPUB and Kindle. Book excerpt: Cloud computing is omnipresent nowadays, as it allows for a fine-grained partitioning of data center resources and for flexibly providing access to these resources. This partitioning and provisioning is achieved by hosting several Virtual Machines (VM) on the same physical machine. In contrast to commercial clouds, the performance of VMs in a private cloud is not captured by Service Level Agreements, and thus, all VMs are treated as processes of equal importance. As users operate different numbers of VMs and these VMs utilize different amounts of physical resources, this equal treatment of VMs leads to users receiving unequal amounts of physical resources. This thesis improves this situation by defining an efficient approach to enforce fairness in private clouds.This thesis shows that cloud resources are best controlled by changing priorities of VMs to access physical resources of their host and that no assumptions on utility functions can be made during this step. The premiss of this thesis that it is fair to constrain greedy users in favor of less greedy users requires a metric that quantifies the greediness of users based on their multi-resource self-servings from a shared resource pool. Thus, the Greediness Metric is developed based on a questionnaire among more than 600 participants on the intuitive understanding of greediness and fairness. The Greediness Metric is refined to define cloud fairness in a way that outperforms all existing cloud fairness definitions. To demonstrate the practical applicability of this cloud fairness definition, OpenStack is extended by an according service. The processing overhead of this service is evaluated and it is proven that it enforces fairness among users by coordinating the VM prioritization on hosts.

This book was released on 2016 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resource allocation in cloud computing determines the allocation of computer and network resources of service providers to service requests of cloud users for meeting the cloud users' service requirements. The efficient and effective resource allocation determines the success of cloud computing. However, it is challenging to satisfy objectives of all service providers and all cloud users in an unpredictable environment with dynamic workload, large shared resources and complex policies to manage them. Many studies propose to use centralized algorithms for achieving optimal solutions for resource allocation. However, the centralized algorithms may encounter the scalability problem to handle a large number of service requests in a realistically satisfactory time. Hence, this dissertation presents two studies. One study develops and tests heuristics of centralized resource allocation to produce near-optimal solutions in a scalable manner. Another study looks into decentralized methods of performing resource allocation. The first part of this dissertation defines the resource allocation problem as a centralized optimization problem in Mixed Integer Programming (MIP) and obtains the optimal solutions for various resource-service problem scenarios. Based on the analysis of the optimal solutions, various heuristics are designed for efficient resource allocation. Extended experiments are conducted with larger numbers of user requests and service providers for performance evaluation of the resource allocation heuristics. Experimental results of the resource allocation heuristics show the comparable performance of the heuristics to the optimal solutions from solving the optimization problem. Moreover, the resource allocation heuristics demonstrate better computational efficiency and thus scalability than solving the optimization problem.The second part of this dissertation looks into elements of service provider-user coordination first in the formulation of the centralized resource allocation problem in MIP and then in the formulation of the optimization problem in a decentralized manner for various problem cases. By examining differences between the centralized, optimal solutions and the decentralized solutions for those problem cases, the analysis of how the decentralized service provider-user coordination breaks down the optimal solutions is performed. Based on the analysis, strategies of decentralized service provider-user coordination are developed.

Download or read book The Age of Decentralization written by Sam Ghosh and published by CRC Press. This book was released on 2024-10-15 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Age of Decentralization talks about various decentralization technologies including Web3, decentralized identity, and decentralized storage, and how they can be incorporated in traditional tech architectures to improve technical and business performance. In this book, the authors take us on a journey through the tech landscape, exploring how decentralized technologies, including Web3, are on the verge of becoming mainstream and offer a practical roadmap for understanding and embracing this shift. Web2 brought us "the great centralization" by centralizing not only data but also business processes, blurring the industry boundaries. So, payment platforms started offering e-commerce services and ride-hailing services started delivering food. Scale became the most effective moat. But, at the same time, these huge platforms became a magnet for security threats and started violating user privacy rights and consumer rights. The authors argue that the technological, regulatory, and social landscape is ready for the next evolution of technology systems as decentralization technologies get incorporated into traditional architectures. This book serves as a guide for readers to understand the fundamentals of Web3 along with other decentralized technologies and creates a framework for incorporating them into traditional architectures. At the same time, the authors explore the organization level as well as the macro implications of decentralized technologies.

Download or read book Techniques for Decentralized and Dynamic Resource Allocation written by Lorenzo Ferrari and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates three different resource allocation problems, aiming to achieve two common goals: i) adaptivity to a fast-changing environment, ii) distribution of the computation tasks to achieve a favorable solution. The motivation for this work relies on the modern-era proliferation of sensors and devices, in the Data Acquisition Systems (DAS) layer of the Internet of Things (IoT) architecture. To avoid congestion and enable low-latency services, limits have to be imposed on the amount of decisions that can be centralized (i.e. solved in the "cloud") and/or amount of control information that devices can exchange. This has been the motivation to develop i) a lightweight PHY Layer protocol for time synchronization and scheduling in Wireless Sensor Networks (WSNs), ii) an adaptive receiver that enables Sub-Nyquist sampling, for efficient spectrum sensing at high frequencies, and iii) an SDN-scheme for resource-sharing across different technologies and operators, to harmoniously and holistically respond to fluctuations in demands at the eNodeB' s layer. The proposed solution for time synchronization and scheduling is a new protocol, called PulseSS, which is completely event-driven and is inspired by biological networks. The results on convergence and accuracy for locally connected networks, presented in this thesis, constitute the theoretical foundation for the protocol in terms of performance guarantee. The derived limits provided guidelines for ad-hoc solutions in the actual implementation of the protocol. The proposed receiver for Compressive Spectrum Sensing (CSS) aims at tackling the noise folding phenomenon, e.g., the accumulation of noise from different sub-bands that are folded, prior to sampling and baseband processing, when an analog front-end aliasing mixer is utilized. The sensing phase design has been conducted via a utility maximization approach, thus the scheme derived has been called Cognitive Utility Maximization Multiple Access (CUMMA). The framework described in the last part of the thesis is inspired by stochastic network optimization tools and dynamics. While convergence of the proposed approach remains an open problem, the numerical results here presented suggest the capability of the algorithm to handle traffic fluctuations across operators, while respecting different time and economic constraints. The scheme has been named Decomposition of Infrastructure-based Dynamic Resource Allocation (DIDRA).
