Modern IT Infrastructure and Operations

The IT manager role has expanded faster than the language used to describe it. The job now spans leadership, infrastructure, security, service delivery, project management, and governance, often in environments that change faster than any single person can track. Most books written for this audience cover one of those areas in depth. Practitioners need all of them, integrated. Modern IT Infrastructure and Operations was written to be that integrated reference. This book covers what an IT manager needs to understand to lead, design, operate, and improve a modern IT environment, written from operational practice rather than abstract theory. Each chapter is grounded in real operational decisions, with case examples showing how the concepts apply when the environment is messy and the deadline is tight. Coverage includes:The modern IT manager role, strategy alignment, building high-performing teams, and IT governanceServers, storage, networking, data center operations, cloud and virtualization, and monitoring and capacity planningSecurity, compliance, risk management, and business continuity and disaster recoveryIT service management including incident, problem, and change managementIT project management fundamentals, methodology selection, project planning, and scope definition The book references established frameworks where they apply, including ITIL, NIST, ISO, PMI, and SAFe, with attribution to their published sources. The goal is not to reproduce those frameworks but to show how they apply in day-to-day IT management decisions. Audience: IT managers, directors, and senior technical leaders responsible for operational environments. Graduate students in IT management programs. Engineers preparing to move into management roles. Consultants and advisors who need a structured reference across the full scope of IT operations. This book is the first volume in a two-part series on IT management. The second volume, IT Project Delivery and Operational Excellence: Governance, Execution, Metrics, and Continuous Improvement, continues with project execution at scale, portfolio management, performance metrics, and continuous improvement programs.
