Overview

DevOpsEx: Mastering Enterprise DevOps Experience (DevEx) & SRE at Scale is a practical and narrative-driven guide to transforming fragmented, locally-optimized DevOps into standardized, secure, and resilient operations at the group level-especially in regulated sectors such as banking, insurance, and critical infrastructure. Structured across five progressive parts, the book combines real-world architecture, hands-on tooling strategies, and fictional case-driven learning to reflect how enterprise-scale DevOps transformations unfold: unevenly, politically, and under pressure. Part I - Systems in Motion (Chapters 1-30) The first thirty chapters blend technical insight with narrative storytelling. Beginning with The Call, the story introduces a protagonist tasked with rescuing a multinational organization from deployment failures, siloed tooling, and mounting compliance risks. As the chapters unfold, each tool or concept-Jenkins, GitLab, Vault, Docker, Snyk, Jira, Terraform, ArgoCD, Grafana, and more-is explored through the lens of escalating incidents, executive tension, and infrastructure complexity. Readers follow a journey of recovery and evolution, experiencing first-hand the organizational resistance, misaligned incentives, and real-world consequences of poor DevOps hygiene. Every fictional episode is tightly coupled with accurate, in-depth exposure to the tool's capabilities, misuses, and strategic applications-offering both drama and documentation in a single narrative stream. Part II - Foundations Under Pressure (Chapters 31-50) The Redux chapters revisit tools introduced earlier-now under new organizational pressures: scale, audit, security, and governance. Here, the book shifts from introducing tools to hardening them: Terraform, GitLab, and Jenkins are re-evaluated for compliance readiness. SonarQube and Snyk are deployed as policy enforcers, not optional quality checks. CI/CD pipelines are redesigned with rollback strategies, signing requirements, and artifact lineage. This section reflects the reality many readers face: tools chosen in good faith become liabilities if not refactored for enterprise constraints. Part III - People, Politics, and Process (Chapters 51-83) This section moves beyond technology into the cultural, psychological, and managerial dimensions of DevOps at scale. Topics include: The cost of autonomy without accountability Burnout and alert fatigue Platform adoption resistance Psychological safety and leadership failures DevRel, communication, and the politics of platform governance Readers explore how DevOps transformations often stall-not due to technical failure, but due to invisible resistance, unmet human needs, or poorly aligned incentives. This section is essential for anyone tasked with change management, platform enablement, or cross-team governance. Part IV - Migrations, Metrics, and Mandates (Chapters 84-100) The final part of the book provides actionable frameworks for navigating complex transformations: Designing DevOps migration roadmaps Rationalizing CI/CD platforms Managing policy enforcement without disrupting autonomy Addressing duplication, technical debt, and the cost of tool proliferation It offers readers a synthesis of earlier lessons with practical playbooks, strategic decision models, and readiness patterns to guide large-scale transformations.
