PREFACE In recent years, the telecommunications industry has witnessed a profound transformation, driven by the convergence of cloud-native paradigms, container orchestration, and artificial intelligence. “Cloud-Native 5G: Architecting Telecom with Kubernetes and AI” is born out of the recognition that tomorrow’s networks must be agile, scalable, and intelligent enough to meet ever-evolving demands—from ultralow-latency industrial automation to immersive augmented-reality experiences. Rather than simply applying legacy architectures to next-generation radio access and core networks, we now have the opportunity to reimagine every layer of the telecom stack through cloud-native principles: microservices, declarative APIs, immutable infrastructure, continuous delivery, and observability. This book is intended as both a roadmap and a hands-on guide for network architects, DevOps engineers, AI practitioners, and decision-makers who are charting a course toward fully software-defined, self-optimizing 5G systems. We begin by exploring the fundamental motivations for cloud-native 5G: the need to accelerate time-to-market, dynamically scale resources, optimize capital and operational expenditures, and inject predictive intelligence into network operations. From there, we delve into the core building blocks of a cloud-native telecom stack: Kubernetes as the orchestration substrate, service meshes for secure and resilient communications, and CI/CD pipelines to automate deployments across distributed edge and regional clusters. Artificial intelligence sits at the heart of the transformation. In early chapters, we introduce machine-learning workflows tailored for network analytics—how to collect, cleanse, and label telemetry at scale; how to train and validate models that predict load, detect anomalies, and anticipate faults; and how to deploy inference engines as lightweight microservices at the network edge. Later sections demonstrate how reinforcement learning and closed-loop control can enable networks to self-tune parameters—orchestrating spectrum allocation, beamforming, and load-balancing in real time—while minimizing human intervention. As the reader progresses, use cases will bring theory to life: implementing cloud-native network slicing to guarantee differentiated SLAs across diverse verticals; leveraging AI-driven traffic steering to optimize quality-of-experience in mobile broadband and ultra-reliable low-latency contexts; and integrating open-source 5G cores with commercial telco cloud platforms. Each chapter balances conceptual clarity with code snippets, architectural diagrams, and references to leading projects—offering practical guidance whether you’re evaluating CNCF-backed network function virtualization (NFV) frameworks or building proprietary AI pipelines. We also address organizational considerations: evolving teams toward DevTelco mindsets, redefining release management and security practices for containerized network functions, and fostering collaboration between data scientists, software engineers, and network operators. The book concludes with a forward-looking perspective on 6G trends—how terahertz communications, distributed intelligence, and digital twins may further disrupt the telecom landscape—and where open-source communities can drive innovation. Whether you’re an engineer tasked with migrating legacy network functions into Kubernetes clusters, a researcher designing novel AI-based management algorithms, or an executive charting your company’s strategic roadmap, this volume aims to equip you with both the conceptual frameworks and the hands-on techniques necessary to architect resilient, scalable, and intelligent 5G systems. The journey toward cloud-native telco is complex—but with Kubernetes and AI as your allies, it is also the most exciting frontier in digital infrastructure today. Authors

PREFACE In an era defined by rapid technological change and mounting business pressures, organizations face the dual challenge of sustaining legacy systems while embracing the agility, scalability, and resilience of cloud-native platforms. Enterprise DevOps Architecture: From Legacy Systems to Cloud-Native Platforms offers a pragmatic roadmap for navigating this transformation. Drawing on real-world case studies, industry best practices, and the collective wisdom of DevOps pioneers, this volume illuminates how enterprises can evolve their IT foundations, integrate people and processes, and harness automation at scale. The journey begins by tracing the evolution of enterprise IT and explaining why traditional siloed approaches must give way to continuous delivery and iterative feedback loops. We then establish the core principles and pillars of enterprise DevOps, from collaboration and shared ownership to metrics-driven decision making and “shift-left” practices that embed quality and security throughout the development lifecycle. As many organizations wrestle with monolithic, mission-critical applications, Chapter 3 guides you through the assessment and migration of legacy systems. You’ll learn to evaluate technical debt, prioritize modernization strategies (Rehost, Refactor, Replat form, and more), and define a phased roadmap that minimizes disruption while maximizing business value. Transitioning to cloud-native architectures demands fresh design paradigms. In Chapter 4, we explore patterns such as microservices, containerization, and service meshes, detailing how they enable resilient, self-healing systems. Chapter 5 then dives into CI/CD pipelines at enterprise scale, illustrating techniques for parallel testing, blue-green and canary deployments, and strategies for scaling pipelines across thousands of services. Automation is the lifeblood of DevOps. Chapter 6 examines Infrastructure as Code—from declarative frameworks like Terraform and Pulu mi to idempotent configuration and policy-as-code. We demonstrate how to codify standards, enforce guardrails, and manage drift in dynamic environments. Security and compliance cannot be afterthoughts. Chapter 7 brings together DevSecOps practices, offering a blueprint for integrating vulnerability scanning, secrets management, and audit-friendly controls without slowing innovation. Building on that, Chapter 8 covers monitoring, observability, and SRE practices, showing how service-level objectives and error budgets drive reliability and continuous improvement. With a plethora of specialized tools available, Chapter 9 unpacks DevOps toolchain integration and orchestration, advising on how to select, connect, and govern tools for source control, build automation, artifact repositories, and beyond. Recognizing that technology alone cannot guarantee success, Chapter 10 addresses organizational change management—how to cultivate a culture of experimentation, distributed ownership, and relentless learning. Finally, Chapter 11 looks ahead to hybrid and multi-cloud DevOps strategies, where enterprises leverage the best attributes of public clouds, private data centers, and edge environments. We discuss network connectivity, data gravity, and policy consistency across heterogeneous landscapes. By the end of this book, practitioners, architects, and leaders will possess a comprehensive framework for transforming monolithic estates into agile, cloud-native platforms. Whether you’re just beginning your DevOps journey or seeking to elevate an existing practice to enterprise scale, the insights within will equip you to accelerate delivery, improve quality, and align technology investments with strategic business outcomes.
