Under today’s shortened fiscal horizons and contracted time-to-market schedules, traditional approaches to capacity planning are seen by management as inflating production schedules. In the face of relentless pressure to get things done faster, this book facilitates rapid forecasting of capacity requirements, based on opportunistic use of available performance data and tools so that management insight is expanded but production schedules are not. The book introduces such concepts as an iterative cycle of improvement called "The Wheel of Capacity Planning," and Virtual Load Testing, which provides a highly cost-effective method for assessing application scalability.

To solve performance problems in modern computing infrastructures, often comprising thousands of servers running hundreds of applications, spanning multiple tiers, you need tools that go beyond mere reporting. You need tools that enable performance analysis of application workflow across the entire enterprise. That's what PDQ (Pretty Damn Quick) provides. PDQ is an open-source performance analyzer based on the paradigm of queues. Queues are ubiquitous in every computing environment as buffers, and since any application architecture can be represented as a circuit of queueing delays, PDQ is a natural fit for analyzing system performance. Building on the success of the first edition, this considerably expanded second edition now comprises four parts. Part I contains the foundational concepts, as well as a new first chapter that explains the central role of queues in successful performance analysis. Part II provides the basics of queueing theory in a highly intelligible style for the non-mathematician; little more than high-school algebra being required. Part III presents many practical examples of how PDQ can be applied. The PDQ manual has been relegated to an appendix in Part IV, along with solutions to the exercises contained in each chapter. Throughout, the Perl code listings have been newly formatted to improve readability. The PDQ code and updates to the PDQ manual are available from the author's web site at www.perfdynamics.com

Annotation The complete guide to planning and building E-business sites! Ensure functionality through performance modeling and capacity planning methods -- correctly analyze and project site needs and performance! Keep your site from crashing, losing money and customer confidence: ensure scalability and handle peak demands. Foreword by Jim Gray: Microsoft Research and 1998 ACM Turing Award Recipient. In 1999, slow E-commerce sites cost their owners $44 billion in lost revenue -- and site failures have embarrassed companies from Britannica to eBay, Victoria's Secret to Charles Schwab. In Scaling for e-Business, two of the world's leading Web performance experts present powerful techniques for characterizing, predicting, anticipating, and addressing every aspect of E-commerce site performance. Scaling for e-Business demonstrates how to characterize E-commerce workloads more accurately than any book published yet. It clearly demonstrates techniques for analyzing the performance of authentication and payment services; modeling contention for software servers; modeling and planning for communications infrastructure; and most importantly, forecasting and addressing peak demand. Finally, the Web/E-Commerce developer will discover how to evaluate and project the long-term impact of changes in his/her site visitor profile -- even the growth of non-PC devices and traffic from "intelligent agents" such as comparative shopping bots. Daniel A. Menasce is Professor of Computer Science at George Mason University, and a fellow of the Association for Computing Machinery. He holds a Ph.D. in Computer Science from UCLA. Virgilio A.F. Almeida Professor of Computer Science at the Federal University of Minas Gerais, Brazil, holds a Ph.D. in Computer Science from Vanderbilt University, and formerly held a visiting research position at Xerox PARC. Their research interests include performance modeling and capacity planning for large-scale Web and e-commerce systems.

Practical systems modeling: planning performance, availability, security, and more Computing systems must meet increasingly strict Quality of Service (QoS) requirements for performance, availability, security, and maintainability. To achieve these goals, designers, analysts, and capacity planners need a far more thorough understanding of QoS issues, and the implications of their decisions. Now, three leading experts present a complete, application-driven framework for understanding and estimating performance. You'll learn exactly how to map real-life systems to accurate performance models, and use those models to make better decisions--both up front and throughout the entire system lifecycle. Coverage includes: State-of-the-art quantitative analysis techniques, supported by extensive numerical examples and exercises QoS issues in requirements analysis, specification, design, development, testing, deployment, operation, and system evolution Specific scenarios, including e-Business and database services, servers, clusters, and data centers Techniques for identifying potential congestion at both software and hardware levels Performance Engineering concepts and tools Detailed solution techniques including exact and approximate MVA and Markov Chains Modeling of software contention, fork-and-join, service rate variability, and priority About the Web Site The accompanying Web site provides companion Excel workbooks that implement many of the book's algorithms and numerical examples.

This book is intended to describe how to leverage emerging technologies big data analytics and SDN, to address challenges specific to LTE and IP network performance and fault management data in order to more efficiently manage and operate an LTE wireless networks. The proposed integrated solutions permit the LTE network service provider to operate entire integrated network, from RAN to Core , from UE to application service, as one unified system and correspondingly collect and align disparate key metrics and data, using an integrated and holistic approach to network analysis. The LTE wireless network performance and fault involves the network performance and management of network elements in EUTRAN, EPC and IP transport components, not only as individual components, but also as nuances of inter-working of these components. The key metrics for EUTRAN include radio access network accessibility, retainability, integrity, availability and mobility. The key metrics for EPC include MME accessibility, mobility and capacity, SGW, PGW capacity and connectivity. In the first parts of the book, the authors describe fundamental analytics techniques, and various key network partitions - RAN, Backhaul, Metro and Core of a typical LTE Wireless Service Provider Network. The second part of the book develops more advanced analytic techniques that can be used to solve complex wireless network problems. The second part of this book also describes practical and novel solutions for LTE service network performance and fault management systems using big data engineering. Self-organizing network (SON) architecture is presented as a way to utilize network performance and fault analytics to enable network automation. SON can significantly improve operational efficiencies and speed up network deployment. This book provides various ways to leverage data science to more intelligently and reliably to automate and manage a wireless network. The contents of the book should be useful to professional engineers and networking experts involved in LTE network operations and management. The content will also be of interest to researchers, academic and corporate, interested in the developments in fault analytics in LTE networks.

Programming multi-core and many-core computing systems Sabri Pllana, Linnaeus University, Sweden Fatos Xhafa, Technical University of Catalonia, Spain Provides state-of-the-art methods for programming multi-core and many-core systems The book comprises a selection of twenty two chapters covering: fundamental techniques and algorithms; programming approaches; methodologies and frameworks; scheduling and management; testing and evaluation methodologies; and case studies for programming multi-core and many-core systems. Program development for multi-core processors, especially for heterogeneous multi-core processors, is significantly more complex than for single-core processors. However, programmers have been traditionally trained for the development of sequential programs, and only a small percentage of them have experience with parallel programming. In the past, only a relatively small group of programmers interested in High Performance Computing (HPC) was concerned with the parallel programming issues, but the situation has changed dramatically with the appearance of multi-core processors on commonly used computing systems. It is expected that with the pervasiveness of multi-core processors, parallel programming will become mainstream. The pervasiveness of multi-core processors affects a large spectrum of systems, from embedded and general-purpose, to high-end computing systems. This book assists programmers in mastering the efficient programming of multi-core systems, which is of paramount importance for the software-intensive industry towards a more effective product-development cycle. Key features: Lessons, challenges, and roadmaps ahead. Contains real world examples and case studies. Helps programmers in mastering the efficient programming of multi-core and many-core systems. The book serves as a reference for a larger audience of practitioners, young researchers and graduate level students. A basic level of programming knowledge is required to use this book.

Admiral James G. Stavridis, USN, reflects on his tenure as Commander of United States Southern Command (SOUTHCOM). The first Admiral to command Southern Command, Admiral Stavridis broke with tradition from day one, discarding the customary military staff model and creating an innovative organization designed not solely to subdue adversaries, but... to build durable and lasting partnerships. From his unique perspective as commander, Stavridis uses his personal style to describe his vision for the command's role in the Americas, making most of limited resources to create goodwill and mutual respect, while countering illegal drug trafficking, overcoming a dangerous insurgency in Colombia, and responding to humanitarian crises. He devotes chapters to USSOUTHCOM's role in nurturing institutional respect for human rights among military and security forces of the region, advancing health security, and supporting a new regional strategy to counter the increasing challenge of urban and transnational gang violence. Citing the hemisphere's common geography, culture, economy, and history, Stavridis makes a case for a common approach and strategy for defending our "shared home of the Americas" through an international, interagency, and private-public approach, all connected through coherent effective strategic communication--Publisher's description.

FORCEnet is currently defined as the operational construct and architectural framework for naval warfare in the information age that integrates warriors, sensors, networks, command and control, platforms, and weapons into a networked, distributed, combat force that is scalable across all levels of conflict from seabed to space and sea to land. Although this definition views FORCEnet as the operational construct and the architectural framework for the entire transformed Navy, some have viewed FORCEnet merely as an information network and the associated FORCEnet architecture merely as an information systems architecture. FORCEnet Implementation Strategy provides advice regarding both the adequacy of this definition and the actions required to implement FORCEnet.
