Building and operating distributed systems is fundamental to large-scale production infrastructure, but doing so in a scalable, reliable, and efficient way requires a lot of trial and error. In this collection of essays and articles, three Site Reliability Engineers from Google explain how the company has successfully navigated these waters over the past decade.
You ll learn how Google continuously deploys and monitors some of the largest software systems in the world, how it s Site Reliability Engineering team learns and improves after outages, and how they balance risk-taking vs reliability with error budgets."
Описание: Providing a thorough review of automated systems testing to meet the regulatory requirements of the FDA and MHRA, this book focuses on software module, software integration, hardware, and system acceptance testing. It covers current best practices in computer systems testing for the pharmaceutical and related healthcare manufacturing industries. Referencing content from the latest GAMP 4 guide, the author demonstrates how the principles detailed in GAMP 4 can be used to define a pragmatic approach to testing. The book includes techniques for testing large Internet-based systems for compliance with the stringent requirements of regulations such as 21CFR Part 11.

Описание: This book focuses on systems analysis, broadly defined to also include problem formulation and interpretation of proposed alternatives in terms of the value systems of stakeholders. Therefore, the book is a complement, not a substitute to other books when teaching systems engineering and systems analysis. The nature of problem solving discussed in this book is appropriate to a wide range of systems analyses. Thus the book can be used as a stand-alone book for teaching the analysis of systems. Also unique is the inclusion of broad case studies to stress problem solving issues, making How to Do Systems Analysis a complement to the many fine works in systems engineering available today.

Описание: Analysis and Synthesis of Computer Systems presents a broad overview of methods that are used to evaluate the performance of computer systems and networks, manufacturing systems, and interconnected services systems. Aside from a highly readable style that rigorously addresses all subjects, this second edition includes new chapters on numerical methods for queueing models and on G-networks, the latter being a new area of queuing theory that one of the authors has pioneered.This book will have a broad appeal to students, practitioners and researchers in several different areas, including practicing computer engineers as well as computer science and engineering students.Sample Chapter(s)Chapter 1: Basic Tools of Probabilistic Modelling (415 KB)Chapter 3: Queueing Network Models (334 KB)Chapter 5: Markov-Modulated Queues (375 KB)
Описание: Modeling and Analysis of Real-Time and Embedded Systems with UML and MARTE explains how to apply the complex MARTE standard in practical situations. This approachable reference provides a handy user guide, illustrating with numerous examples how you can use MARTE to design and develop real-time and embedded systems and software. . Expert co-authors Bran Selic and S?bastien G?rard lead the team that drafted and maintain the standard and give you the tools you need apply MARTE to overcome the limitations of cyber-physical systems. The functional sophistication required of modern cyber-physical systems has reached a point where traditional code-centric development methods are proving less and less capable of delivering a reliable product in a timely manner. In Modeling and Analysis of Real-Time and Embedded Systems with UML and MARTE, you will learn how to take advantage of modern model-based engineering methods and corresponding industry standards to overcome these limitations. These methods take full advantage of computer-supported automation allowing timely detection of design flaws to reduce engineering risk, leading thereby to better overall product quality and greater productivity.

Rigorous theory and real-world applications for modeling and analysis of the behavior of complex communicating computer systems
Complex communicating computer systems -- computers connected by data networks and in constant communication with their environments -- do not always behave as expected. This book introduces behavioral modeling, a rigorous approach to behavioral specification and verification of concurrent and distributed systems. It is among the very few techniques capable of modeling systems interaction at a level of abstraction sufficient for the interaction to be understood and analyzed. Offering both a mathematically grounded theory and real-world applications, the book is suitable for classroom use and as a reference for system architects.
The book covers the foundation of behavioral modeling using process algebra, transition systems, abstract data types, and modal logics. Exercises and examples augment the theoretical discussion. The book introduces a modeling language, mCRL2, that enables concise descriptions of even the most intricate distributed algorithms and protocols. Using behavioral axioms and such proof methods as confluence, cones, and foci, readers will learn how to prove such algorithms equal to their specifications. Specifications in mCRL2 can be simulated, visualized, or verified against their requirements. An extensive mCRL2 toolset for mechanically verifying the requirements is freely available online; this toolset has been successfully used to design and analyze industrial software that ranges from healthcare applications to particle accelerators at CERN. Appendixes offer material on equations and notation as well as exercise solutions.

Описание: Get the skills you need to do SAD! In a field as exciting and dynamic as System Analysis and Design (SAD), there will always be new techniques and approaches to develop systems more effectively and efficiently. But if you want to succeed in SAD, you'll need a solid foundation of skills you can rely on--no matter what the approach or methodology. That's why Alan Dennis and Barb Wixom's SYSTEMS ANALYSI AND DESIGN focuses on the core set of skills that all analysis must possess--from gathering rewuirements and modeling business needs to creating blueprints for how the system should be built. Now updated and revised, the new edition features reorganized chapters, new topics, and expanded detail. FEATURES: * Focus on doing SAD. This text encourages you to do SAD. After presenting the how and what of each major technique, the text guides you through practice problems and then invites you to use the technique in a project. * New and expanded coverage. The Second Edition presents a new half chapter about the project selection process, as well as more detailed coverage of economic feasibility, process modeling, data modeling, and IT architecture. * New real-life examples, cases, and skills. The book includes a running case, which serves as a template th you can apply to your own work. Chapters also include "Concepts in Action" boxes, which describe how real companies succeeded (and failed) in performing the activities in that chapter. * Object-oriented concepts and techniques. Object-oriented concepts are included throughout the book, and a final chapter focuses on the major elements of UML. * Project-based approach. Topics are presented in the order in which an analyst would encounter them in a typical project. * Tips from the pros. Interviews of seven CIOs on about project selection and management are integrated throughout the book. * Student Web Site.
