The Routing Intent by Leonardo Furtado

Chapter 25: Managing Python Projects with Poetry — Part 1

Bring consistency, clarity, and operational safety to your network automation code.

Chapter 24: Foundation Before Features — Pyenv, Poetry, and Venv, Part 2

Treat Python versions, virtual environments, and dependencies as infrastructure: predictable, auditable, and production-safe.

The Hero Trap: How Network Engineering Myths Undermine Scale, Velocity, and Sanity

How dependence on network heroes leads to technical debt and operational and business risks

Chapter 23: Foundation Before Features — Pyenv, Poetry, and Venv, Part 1

Standardizing runtimes across laptops, jump hosts, and CI environments for reliability and efficiency

Chapter 22: Taming the Python Jungle — From Pip to Production

Why package management is the foundation of clean, scalable NetDevOps workflows.

Chapter 21: From Scripts to Systems with Python OOP - Part 2

Chapter 20: From Scripts to Systems with Python OOP - Part 1

Why OOP solves the mess of sprawling logic, especially in infrastructure where devices, connections, and services have distinct identities and behaviors.

Chapter 19: Structuring Network Data for Scale and Speed with Arrays

Learn how Python arrays (and their powerful cousins in NumPy) bring structure, speed, and clarity to network engineering workflows.

Shipping Without Fear: Inside Our Zero-Downtime Deployment Culture

At hyperscale, speed doesn’t kill. Poor culture does. We unpack how safe rollouts are built through trust, clarity, and muscle memory, not just pipelines and scripts.

Chapter 18: Writing Smarter Network Scripts with Python Lambdas

Python lambdas help you write composable, testable, and elegant logic for device filtering, config validation, and more.

If the Control Plane Fails, Nothing Else Matters

Your data plane moves packets. Your control plane moves decisions. If the latter breaks, the former doesn’t matter. This is how we protect the network’s brain.

When $100 Million Cloud Bills Make Sense

Not all expensive cloud bills are bad, and not all cheap ones are smart. Learn how to interpret cloud cost through the lens of architecture, performance, and business alignment.
