Книга "Beyond Redundancy" рассматривает вопросы географической редундантности компьютерных систем и ее роли в обеспечении доступности и надежности сервисов. Авторы исследуют, как географическая редундантность может помочь предотвратить отказы оборудования, программного обеспечения и человеческих ошибок, а также как она может быть полезна в случае стихийных бедствий или террористических актов. Книга содержит теоретические основы и практические рекомендации по проектированию, тестированию и анализу географически редундантных конфигураций. Она также предлагает общие рассуждения о балансе между капитальными и операционными расходами, который определяет вопросы системной редундантности и географической редундантности. Книга является ценным ресурсом для специалистов в области планирования сетей и систем, IT-персонала, системных архитекторов, инженеров, разработчиков, тестировщиков и консультантов по восстановлению после катастрофы и бизнес-континуитету. В книге также приведен пример географически редундантной системы.
How Geographic Redundancy and Business Continuity Can Benefit Modern Enterprises Glenn E. Davis Systems analysis, integration, and modern information technology (IT) infrastructure have become increasingly interwoven with business operations in today’s economy. Yet, busnless organizations are a vulnerable target for natural disasters and manned-made events, which can disrupt both short-term day-to-day operation and longer-term processes and services. In Beyond Redunancy: The Valued Benefits of Geographical Redundancy for Service Availability and Supply Chain Resilience, author Richard C. Terwilliger addresses the current issues and contributes to the nascent—but growing—literature on the benefits of geographic redundancy and business continuity.
The first section of the book discusses the economic and operational benefits of business resilience. Section 2 gives an overview of some key factors related to incorporating geographic redundancy into IT systems, focusing on models and metrics used for service availability analysis. Finally, section 3 presents a case study for a large Fortune 500 telecom provider, demonstrating how these technologies are applied in practice. Using insights gleaned from various examples in the real world, the author presents clear steps and guidance for well-founded georedundanly systems architecture, component and system implementation, testing and evaluation, and recommend policy and best practices.
Beyond Redundancy is an interesting read that helps readers understand the context surrounding geographic resililience and overcome the apparent traps and common misconceptions they encounter. Whether you operate an organization in a remote island, rep город smaller town, or an enterprise with a global presence, this compact guidebook should expand your horizons regarding the aesthetic logic behind interconnectivity” and “integrity for extended ICT resiliency.

Описание книги от Eric Bauer
How Geographic Redundancy Can Improve Service Availability and Reliability of Computer-Based Systems Enterprises make significant investments in geographically redundant systems to mitigate the very unlikely risk of a natural or man-made disaster rendering their primary site inaccessible or destroying it completely. While geographic redundancy has obvious benefits for disaster recovery, it is far less obvious what benefit georedundancy offers for more common hardware, software, and human failures. Beyond Redundancy provides both a theoretical and practical treatment of the feasible and likely benefits from geographic redundancy for both service availability and service reliability. The book is organized into three sections: Basics provides the necessary background on georedundancy and service availability Modeling and Analysis of Redundancy gives the technical and mathematical details of service availability modeling of georedundant configurations Recommendations offers specific recommendations on architecture, requirements, design, testing, and analysis of georedundant configurations A complete georedundant case study is included to illustrate the recommendations. The book considers both georedundant systems and georedundant solutions. The text also provides a general discussion about the capital expense/operating expense tradeoff that frames system redundancy and georedundancy. These added features make Beyond Redundancy an invaluable resource for network/system planners, IS/IT personnel, system architects, system engineers, developers, testers, and disaster recovery/business continuity consultants and planners.
