Infrastructure as Code

Introduction Over the past two posts (Building a Scalable Zero Trust Demo environment with Cloudflare and Terraform (Part 1) and Automating Cloudflare Zero Trust at Scale: Terraform, Multi-Cloud, and Identity (Part 2) ), we’ve explored the foundations of building a scalable Zero Trust demo environment and how to automate its deployment with Cloudflare and Terraform. In Part 1, we laid the groundwork by designing a robust, modular Zero Trust architecture. Part 2 took things further, demonstrating how to streamline and scale this setup using Infrastructure as Code principles. Now, in part 3 (final part), we will explore advanced use cases you can demonstrate with this environment. ...

Introduction In Part 1 , we demonstrated how Terraform can streamline reproducible security configurations. In this follow-up, I’ll show how to extend those principles across AWS, Azure, and GCP using Cloudflare Zero Trust. You’ll see how the project’s modular structure, automation, and dynamic routing reduce manual security tasks by up to 80%—based on my own benchmarks. What’s new since Part 1: Custom subnets and improved network segmentation Automated device profiles and dynamic WARP routing Expanded multi-cloud support with updated diagrams Terraform code is now 4100+ lines of code, 87 files and 21 directories (even if the quantity does not mean quality!) with 143 resources Let’s dive into the updated architecture and key modules powering this environment. ...

Disclaimer: This article reflects my personal views and experiences and does not represent the official stance of Cloudflare. It is not an official Cloudflare tutorial or documentation. The project discussed is a personal initiative created independently. Introduction As a Solutions Engineer at Cloudflare, I frequently work with customers exploring Zero Trust security solutions. While Cloudflare offers a 50-user free tier perfect for initial testing, I identified a gap: there was no simple, scalable way to quickly demonstrate the full power of Cloudflare’s Zero Trust platform in a controlled demo environment. ...
