Keeping An Eye On Reliability

The Reliable Past is the eagerly awaited sequel to Russian Silhouettes, Genna Sosonko's marvellous collection of portraits from the golden age of Soviet chess. In this new book, the author again shows himself a perceptive chronicler of a time when chess occupied a unique position in his native country, but he also wanders across its borders with his memories of Dutch World Champion Max Euwe and a touching tribute to the first ever British grandmaster, Tony Miles. From the preface by Garry Kasparov: The Reliable Past presents the reader with a gallery of wonderful pen-portraits that radiate the author?s love of and devotion to chess, yet are tempered by a due measure of objectivity and detachment. Look, it says ? this is the chess world and its heroes, warts and all!

One of the major developments in the computing field has been cloud computing, which enables users to do complicated computations that local devices are unable to handle. The computing power and flexibility that have made the cloud so popular do not come without challenges. It is particularly challenging to decide which resources to use, even when they have the same configuration but different levels of performance because of the variable structure of the available resources. Cloud data centers can host millions of virtual machines, and where to locate these machines in the cloud is a difficult problem. Additionally, fulfilling optimization needs is a complex problem. Reliable and Intelligent Optimization in Multi-Layered Cloud Computing Architectures examines ways to meet these challenges. It discusses virtual machine placement techniques and task scheduling techniques that optimize resource utilization and minimize energy consumption of cloud data centers. Placement techniques presented can provide an optimal solution to the optimization problem using multiple objectives. The book focuses on basic design principles and analysis of virtual machine placement techniques and task allocation techniques. It also looks at virtual machine placement techniques that can improve quality-of-service (QoS) in service-oriented architecture (SOA) computing. The aims of virtual machine placement include minimizing energy usage, network traffic, economical cost, maximizing performance, and maximizing resource utilization. Other highlights of the book include: Improving QoS and resource efficiency Fault-tolerant and reliable resource optimization models A reactive fault tolerance method using checkpointing restart Cost and network-aware metaheuristics. Virtual machine scheduling and placement Electricity consumption in cloud data centers Written by leading experts and researchers, this book provides insights and techniques to those dedicated to improving cloud computing and its services.

Explains fault tolerance in clear terms, with concrete examples drawn from real-world settings Highly practical focus aimed at building "mission-critical" networked applications that remain secure

This book describes the key concepts, principles and implementation options for creating high-assurance cloud computing solutions. The guide starts with a broad technical overview and basic introduction to cloud computing, looking at the overall architecture of the cloud, client systems, the modern Internet and cloud computing data centers. It then delves into the core challenges of showing how reliability and fault-tolerance can be abstracted, how the resulting questions can be solved, and how the solutions can be leveraged to create a wide range of practical cloud applications. The author’s style is practical, and the guide should be readily understandable without any special background. Concrete examples are often drawn from real-world settings to illustrate key insights. Appendices show how the most important reliability models can be formalized, describe the API of the Isis2 platform, and offer more than 80 problems at varying levels of difficulty.

Trapped between an encroaching tide of privatization and a rocky theoretical shore, educational leadership in America’s public schools is ardently researched and professionally practiced, but frequently besmirched and poorly understood. Despite the intentions of public educators to engage all students with the original power of education, disconnections caused by mandates, ideologies, and theoretical fuzziness render educational leadership unreliable. The capacities necessary for school leadership to function reliably on behalf of all students are well within the grasp of present-day public educators. But, the action or agency sufficient to enacting educational leadership reliably is on hold. Educational leadership throughout US public schools is submarined when disconnections and ideological misdirection impede the primary purpose and the moral obligation of public education. To fulfill the promises of public education and restore the intentions of educational leadership requires that educators, policymakers, and proponents of US public education reimagine the interconnections that yield the primary purpose and moral obligation of public education. Functional educational leadership is examined throughout this book as the agency necessary and sufficient for public education to discard the forces and factors that impose unreliability.
