Computation and Storage in the Cloud is the first comprehensive and systematic work investigating the issue of computation and storage trade-off in the cloud in order to reduce the overall application cost. Scientific applications are usually computation and data intensive, where complex computation tasks take a long time for execution and the generated datasets are often terabytes or petabytes in size. Storing valuable generated application datasets can save their regeneration cost when they are reused, not to mention the waiting time caused by regeneration. However, the large size of the scientific datasets is a big challenge for their storage. By proposing innovative concepts, theorems and algorithms, this book will help bring the cost down dramatically for both cloud users and service providers to run computation and data intensive scientific applications in the cloud. - Covers cost models and benchmarking that explain the necessary tradeoffs for both cloud providers and users - Describes several novel strategies for storing application datasets in the cloud - Includes real-world case studies of scientific research applications - Covers cost models and benchmarking that explain the necessary tradeoffs for both cloud providers and users - Describes several novel strategies for storing application datasets in the cloud - Includes real-world case studies of scientific research applications
Cloud computing is the latest market-oriented computing paradigm which brings software design and development into a new era characterized by “XaaS”, i.e. everything as a service. Cloud workflows, as typical software applications in the cloud, are composed of a set of partially ordered cloud software services to achieve specific goals. However, due to the low QoS (quality of service) nature of the cloud environment, the design of workflow systems in the cloud becomes a challenging issue for the delivery of high quality cloud workflow applications. To address such an issue, this book presents a systematic investigation to the three critical aspects for the design of a cloud workflow system, viz. system architecture, system functionality and quality of service. Specifically, the system architecture for a cloud workflow system is designed based on the general four-layer cloud architecture, viz. application layer, platform layer, unified resources layer and fabric layer. The system functionality for a cloud workflow system is designed based on the general workflow reference model but with significant extensions to accommodate software services in the cloud. The support of QoS is critical for the quality of cloud workflow applications. This book presents a generic framework to facilitate a unified design and development process for software components that deliver lifecycle support for different QoS requirements. While the general QoS requirements for cloud workflow applications can have many dimensions, this book mainly focuses on three of the most important ones, viz. performance, reliability and security. In this book, the architecture, functionality and QoS management of our SwinDeW-C prototype cloud workflow system are demonstrated in detail as a case study to evaluate our generic design for cloud workflow systems. To conclude, this book offers a general overview of cloud workflow systems and provides comprehensive introductions to the design of the system architecture, system functionality and QoS management.

In the era of globalization and liberalization, the world is enjoying high growth as well as suffering from the ill-effects of unequal distribution of its economic outcomes. The activities of anti-government demonstrations in China and across the world via the Occupy Wall Street Movement highlight that inequality has become an international phenomenon. It is apparent in both poor countries under authoritarianism and rich countries governed by a democratic regime. Thus, inequality has become not only a hurdle to development but also a threat to social and political stability. The spread of the Jasmine Revolution across parts of North Africa and the Arab Spring are illustrative of what can happen under certain circumstances.This book confirms the inconsistencies between high growth and increasing inequality via a series of case studies across 11 countries, numerous regions, and OECD members. Many of the case studies draw upon original household surveys. Our findings indicate the seriousness of income inequality, explore factors that have caused the inequality and analyze their economic and social consequences.The book raises, and deals with, three key questions: (1) Can high growth reduce inequality gradually? (2) Can government intervention be effective in equalizing income distribution? (3) Is the income disparity an engine for, or an obstacle of, high growth?
Cloud computing can provide virtually unlimited scalable high performance computing resources. Cloud workflows often underlie many large scale data/computation intensive e-science applications such as earthquake modelling, weather forecasting and astrophysics. During application modelling, these sophisticated processes are redesigned as cloud workflows, and at runtime, the models are executed by employing the supercomputing and data sharing ability of the underlying cloud computing infrastructures. Temporal QOS Management in Scientific Cloud Workflow Systems focuses on real world scientific applications which often must be completed by satisfying a set of temporal constraints such as milestones and deadlines. Meanwhile, activity duration, as a measurement of system performance, often needs to be monitored and controlled. This book demonstrates how to guarantee on-time completion of most, if not all, workflow applications. Offering a comprehensive framework to support the lifecycle of time-constrained workflow applications, this book will enhance the overall performance and usability of scientific cloud workflow systems. - Explains how to reduce the cost to detect and handle temporal violations while delivering high quality of service (QoS) - Offers new concepts, innovative strategies and algorithms to support large-scale sophisticated applications in the cloud - Improves the overall performance and usability of cloud workflow systems
