Modern Enterprise Linux: Infrastructure, Automation, and Cloud Operations

Modern Enterprise Linux: Infrastructure, Automation, and Cloud Operations by Mr. Balaramakrishna Alti explores the dramatic transformation of enterprise IT over the past two decades, where traditional monolithic data centres have evolved into agile, automated, hybrid, and cloud-native environments. At the core of this transformation stands Linux—an open, resilient, and highly adaptable operating system that has become the foundation of modern enterprise infrastructure. This book serves as a comprehensive and practical guide for system administrators, infrastructure engineers, DevOps professionals, and IT leaders who work with Linux in today’s complex and performance-driven environments. The book is written to bridge the gap between traditional Linux system administration and modern cloud-based operations, offering practical insights into configuring, securing, and managing Linux systems at scale. Drawing on real-world enterprise use cases, it covers on-premises, hybrid, and public cloud deployments, while providing hands-on guidance on automation tools such as Ansible, ReaR, and Red Hat Satellite, along with scripting, monitoring, configuration management, and security best practices. Each chapter focuses on a critical aspect of enterprise Linux operations, beginning with core infrastructure concepts and progressing through provisioning, automation, storage, networking, monitoring, security, disaster recovery, and cloud-native operations. While deeply technical, the book is structured to remain approachable, making it equally valuable for seasoned professionals and those beginning their journey in enterprise Linux. Rooted in practical production-environment challenges—where uptime, security, automation, and simplicity are paramount—this book aims to be a reliable companion for professionals seeking to design, operate, and scale secure, efficient, and modern Linux environments in today’s rapidly evolving IT landscape.
