PRODUCTION DEVOPS: The Real-World Engineering Manual: A Practitioner's Field Guide to Scalable Architecture, Automation, and Zero-Downtime Infrastructure

STOP MEMORIZING COMMANDS. START ARCHITECTING PRODUCTION SYSTEMS. Most DevOps tutorials teach you how to run a tool in an isolated sandbox. Production, however, is hostile. Real-world cloud systems face unexpected traffic surges, strict permission boundaries, network partitions, and zero-downtime constraints. Written by Anmol Korla, Production DevOps is an operational field manual bridging the gap between theoretical classroom concepts and real-world 2:00 AM production debugging. INSIDE THIS PRACTICAL MANUAL: - Linux System Internals: Process namespaces (PID, Mount, Net, User), sudoers least-privilege hardening, and socket triage (ss). - Enterprise Containerization: Multi-stage minimal Docker builds, distroless runtimes, bridge networking DNS, and OOM killer survival. - Edge Traffic Management: High-performance Nginx reverse proxying, upstream load pools, automated TLS/SSL termination, and leaky bucket rate limiting. - Closed-Loop CI/CD: Distributed Jenkins controller-agent topologies, declarative Jenkinsfiles, and HMAC-SHA256 GitHub webhook verification. - Full Production Pipeline: End-to-end blue/green deployment cutover scripts with zero-downtime health probes. - Production Incident Field Manual: Step-by-step root cause analysis and exact fixes for top production failure modes (Docker socket permissions, Nginx 502 Bad Gateway, inode exhaustion). >Keep this book by your terminal as your production engineering field guide.
