Introduction

A personal guide

Systems is a personal reference guide that captures the core principles, practices, and lessons I’ve learned in systems administration and engineering. It reflects both timeless fundamentals and evolving approaches in managing and designing complex infrastructures.

This book is meant to be a practical companion—structured to provide clarity and insight for navigating the challenges of modern systems. With each page, you’ll find ideas, tools, and techniques that have shaped my understanding of how systems work and how to make them work better.
