Practical, real-world solutions are given to potential problems covering the entire system life cycle. This book describes how to map real-life systems (databases, data centers, and e-commerce applications) into analytic performance models. The authors elaborate upon these models and use them to help the reader better understand performance issues.
MenascT (computer science, George Mason U.) and Almeida (computer science, U. of Minas Gerais, Brazil) provide a quantitative analysis of Web service availability and a framework for understanding and planning Web services. They discuss benchmarking, load testing, workload forecasting, and performan
This example-driven exploration of capacity planning of computer systems is designed for both practising professionals and those with little mathematical background. It is accompanied by a disk containing a modified version of QSolver/1, a capacity planning modelling package.
This book presents analysis techniques for quantifying and projecting every element of your e-business site's performance and planning for the capacity you need.
Initially, computer systems performance analyses were carried out primarily because of limited resources. Due to ever increasing functional complexity of computational systems and user requirements, performance engineering continues to play a major role in software development. This book assesses the state of the art in performance engineering. Besides revised chapters drawn from two workshops on performance engineering held in 2000, additional chapters were solicited in order to provide complete coverage of all relevant aspects. The first part is devoted to the relation between software engineering and performance engineering; the second part focuses on the use of models, measures, and tools; finally, case studies with regard to concrete technologies are presented. Researchers, professional software engineers, and advanced students interested in performance analysis will find this book an indispensable source of information and reference.
Service computing is a cutting-edge area, popular in both industry and academia. New challenges have been introduced to develop service-oriented systems with high assurance requirements. High Assurance Services Computing captures and makes accessible the most recent practical developments in service-oriented high-assurance systems. An edited volume contributed by well-established researchers in this field worldwide, this book reports the best current practices and emerging methods in the areas of service-oriented techniques for high assurance systems. Available results from industry and government, R&D laboratories and academia are included, along with unreported results from the “hands-on” experiences of software professionals in the respective domains. Designed for practitioners and researchers working for industrial organizations and government agencies, High Assurance Services Computing is also suitable for advanced-level students in computer science and engineering.
A new, quantitative architecture simulation approach to software design that circumvents costly testing cycles by modeling quality of service in early design states. Too often, software designers lack an understanding of the effect of design decisions on such quality attributes as performance and reliability. This necessitates costly trial-and-error testing cycles, delaying or complicating rollout. This book presents a new, quantitative architecture simulation approach to software design, which allows software engineers to model quality of service in early design stages. It presents the first simulator for software architectures, Palladio, and shows students and professionals how to model re...
This book is a literary, social, and political portrait of Alexandria at a high point of its history. Drawing on diaries, letters, and interviews, Michael Haag recovers the lost life of the city, its cosmopolitan inhabitants, and its literary characters. Located on the coast of Africa yet rich in historical associations with Western civilization, Alexandria was home to an exotic variety of people whose cosmopolitan families had long been rooted in the commerce and the culture of the entire Mediterranean world. Alexandria famously excited the imaginations of writers, and Haag folds intimate accounts of E. M. Forster, Greek poet Constantine Cavafy, and Lawrence Durrell into the story of its inhabitants. He recounts the city’s experience of the two world wars and explores the communities that gave Alexandria its unique flavor: the Greek, the Italian, and the Jewish. The book deftly harnesses the sexual and emotional charge of cosmopolitan life in this extraordinary city, and highlights the social and political changes over the decades that finally led to Nasser’s Egypt.
This book provides formal and informal definitions and taxonomies for self-aware computing systems, and explains how self-aware computing relates to many existing subfields of computer science, especially software engineering. It describes architectures and algorithms for self-aware systems as well as the benefits and pitfalls of self-awareness, and reviews much of the latest relevant research across a wide array of disciplines, including open research challenges. The chapters of this book are organized into five parts: Introduction, System Architectures, Methods and Algorithms, Applications and Case Studies, and Outlook. Part I offers an introduction that defines self-aware computing system...
