Foundations of Modern Networking is a comprehensive, unified survey of modern networking technology and applications for today’s professionals, managers, and students. Dr. William Stallings offers clear and well-organized coverage of five key technologies that are transforming networks: Software-Defined Networks (SDN), Network Functions Virtualization (NFV), Quality of Experience (QoE), the Internet of Things (IoT), and cloudbased services. Dr. Stallings reviews current network ecosystems and the challenges they face–from Big Data and mobility to security and complexity. Next, he offers complete, self-contained coverage of each new set of technologies: how they work, how they are architected, and how they can be applied to solve real problems. Dr. Stallings presents a chapter-length analysis of emerging security issues in modern networks. He concludes with an up-to date discussion of networking careers, including important recent changes in roles and skill requirements. Coverage: Elements of the modern networking ecosystem: technologies, architecture, services, and applications Evolving requirements of current network environments SDN: concepts, rationale, applications, and standards across data, control, and application planes OpenFlow, OpenDaylight, and other key SDN technologies Network functions virtualization: concepts, technology, applications, and software defined infrastructure Ensuring customer Quality of Experience (QoE) with interactive video and multimedia network traffic Cloud networking: services, deployment models, architecture, and linkages to SDN and NFV IoT and fog computing in depth: key components of IoT-enabled devices, model architectures, and example implementations Securing SDN, NFV, cloud, and IoT environments Career preparation and ongoing education for tomorrow’s networking careers Key Features: Strong coverage of unifying principles and practical techniques More than a hundred figures that clarify key concepts Web support at williamstallings.com/Network/ QR codes throughout, linking to the website and other resources Keyword/acronym lists, recommended readings, and glossary Margin note definitions of key words throughout the text

This textbook has been meticulously crafted with a singular purpose: offering a comprehensive and practical guide to Agile Software Development. In the forthcoming chapters, we will delve into theintricacies of Agile methodologies, explore their underlying principles, and investigate the compelling reasons behind their prominence in the software development industry. Section I: Introduction to Iterative Development, Evolutionary, and Adaptive Development, Our journeybegins with an exploration of fundamental concepts: Iterative Development, Evolutionary Development,and Adaptive Development. These approaches break free from conventional linear development processesand prioritize flexibility, risk management, and client-driven planning. This chapter will discuss the meritsof time-boxed iterative development, evolutionary requirements analysis, incremental delivery, and theultimate goal of evolutionary delivery. Section II: Serves as a bridge between theory and practice within the Agile realm. Here, we define AgileDevelopment, categorize various methodologies, and delve deep into the Agile Manifesto and its guidingprinciples. Additionally, we explore Agile project management, emphasizing the crucial role ofcommunication, feedback, and the human element. The chapter culminates in an exploration of specificAgile methods and a balanced discussion of the ongoing discourse surrounding "Agile Hype." Section III: Motivation and Evidence, Understanding the motivation underpinning Agile is fundamental toappreciating its significance. In Chapter 3, we illuminate the imperatives for change in software projectsand how iterative development addresses these challenges. We critique the limitations of the traditionalWaterfall model and provide a comprehensive review of supporting evidence, including research findings,historical project data, and expert opinions, all converging to fortify the case for iterative development. Section IV: Fundamentals of DevOps and Technical View, Agile methodologies extend beyond softwaredevelopment into the realm of DevOps. Chapter 4 introduces the foundational principles of DevOps and itspivotal role in contemporary development practices. We delve into the building blocks of DevOps, thevital metrics and measurement perspective, and the process view that fosters seamless collaborationbetween development and operations teams. The section IV concludes with an in-depth exploration of thetechnical facets, including topics like automatic releasing, infrastructure as code, and specification byexample, enriched by real-world case studies. Upon completing this textbook, you will comprehensively comprehend Agile Software Development andDevOps. Whether you are a student embarking on a career in software development or an industryprofessional looking to stay at the forefront of the field, the knowledge and insights provided here will equip you with the tools to excel in the dynamic world of software development. Let us embark on this enlightening journey together, embracing agility, adaptability, and excellence in software development.
Fundamentals of Software Testing
Software testing has greatly evolved since the first edition of this book in 2011. Testers are now required to work in "agile" teams and focus on automating test cases. It has thus been necessary to update this work, in order to provide fundamental knowledge that testers should have to be effective and efficient in today's world. This book describes the fundamental aspects of testing in the different lifecycles, and how to implement and benefit from reviews and static analysis. Multiple other techniques are approached, such as equivalence partitioning, boundary value analysis, use case testing, decision tables and state transitions. This second edition also covers test management, test progress monitoring and incident management, in order to ensure that the testing information is correctly provided to the stakeholders. This book provides detailed course-study material for the 2023 version of the ISTQB Foundation level syllabus, including sample questions to help prepare for exams.
