Practical Web Operations for Developers and DevOps: Nginx, HTTPS, Monitoring, Backup, and Kubernetes Basics

Author: Stellan Cross

Description: You've deployed your application. The server is running. But then the 502 error appears, and you have no idea where to start. This is the moment when development ends and operations begins—a shift that many developers face unprepared. The difference between a hobby project and a production system isn't just code quality; it's how you handle failures, secure data, and plan for the unexpected. The good news: production operations is a learnable skill, and this book gives you the structured practice to master it. Practical Web Operations for Developers and DevOps is a comprehensive, hands-on guide written by Stellan Cross. It bridges the gap between deploying code and keeping it reliably running, targeting the critical post-deployment phase that so many tutorials skip. The book covers the entire lifecycle of production web operations across six logical parts. Part 1 establishes the foundation. You'll understand why production is different from development, learn the components of a web system (client, DNS, server, reverse proxy, application, database), and prepare an Ubuntu VPS for safe operation. This includes hardening SSH, configuring UFW, creating non-root users, and setting up a recommended directory structure for apps, logs, backups, and configs. Part 2 teaches you to master traffic routing. You'll configure Nginx as a reverse proxy, proxy requests to backend services, and handle multiple applications on one VPS using separate server blocks and internal port mapping. You'll also set up domains and DNS with A and CNAME records, install and renew SSL certificates from Let's Encrypt using Certbot, and fix common HTTPS issues like mixed content and redirect loops. Part 3 builds your debugging discipline. You'll learn where logs live for applications, Nginx, and the system, and how to read them using tail, journalctl, and Docker logs. The chapter on fixing common web errors is particularly valuable: you'll step through 502 Bad Gateway, 504 Gateway Timeout, and unreachable services, using a systematic outside-in approach to narrow down the cause. You'll also monitor server resources—CPU, RAM, disk, network—and know when to upgrade. Part 4 shifts to proactive monitoring. You'll differentiate monitoring from logging, track key metrics, monitor Docker containers, implement health check endpoints, and set up uptime monitoring with tools like Uptime Kuma. You'll learn how to respond to downtime alerts and manage long-term log storage with logrotate to prevent disk space disasters. Part 5 focuses on data safety and security. You'll build a backup strategy covering databases (mysqldump, pg_dump), uploaded files, and configuration. You'll compare local, remote, and cloud backup options, establish a suitable schedule, and practice restore procedures so you're never caught off guard. The book also covers moving an application to a new VPS and post-restore verification. Security chapters guide you to minimize exposed ports, protect SSH, secure .env files and secrets, and avoid dangerous operational habits. Part 6 introduces Kubernetes responsibly. You'll learn why Kubernetes was created, how it differs from Docker Compose, and the honest tradeoffs. Using a local cluster (minikube or kind), you'll deploy a simple application, expose it with a Service or Ingress, perform rolling updates and rollbacks, and view logs. The book ends with daily, weekly, and monthly operations checklists, an incident response process, and a curated learning path for continuing beyond this book. What makes this book unique is its problem-driven, production-tested approach. Every command is annotated, every config file explained, and every error scenario reconstructed from real-world patterns. Clear diagrams illustrate architecture and traffic flow, helping you visualize complex concepts. The book begins with an author's note that sets expectations, explains how to use the companion terminal exercises safely, and clarifies scope boundaries. You won't find enterprise Kubernetes or advanced Prometheus here—just focused, practical operations for small-to-medium systems. This book is written for junior DevOps engineers, backend developers, indie hackers, and technical founders who can deploy code but lack the confidence to manage it in production. If you manage a VPS with Docker Compose, run a small-to-medium web service, and want to replace anxiety with methodical troubleshooting, this is your playbook. With over 58,000 words of practical instruction across 20 chapters and 6 parts, spanning an estimated 258 pages, every page delivers immediate, applicable value. You get step-by-step workflows, real error patterns, safety warnings, and verification checklists—no filler. Stop hoping your server stays up. Learn to make it stay up.

AI summary: Practical Web Operations for Developers and DevOps is a comprehensive guide covering the complete lifecycle of production web operations. It covers Nginx reverse proxy configuration, HTTPS setup with Let's Encrypt, server monitoring, backup and restore strategies, and Kubernetes basics. The book targets developers and junior DevOps engineers who need to move from deployment to reliable production operations, with step-by-step workflows and real error patterns.
