Shifting left at enterprise scale: how we manage Cloudflare with Infrastructure as Code

Summary

The article outlines Cloudflare's approach to managing its infrastructure using Infrastructure as Code (IaC) principles, specifically focusing on the implementation of Terraform and a custom CI/CD pipeline. It emphasizes the importance of shifting security checks left in the software development lifecycle to catch misconfigurations early. The authors detail their governance architecture, which includes maintaining a strong security baseline through Policy as Code, and the challenges faced during the transition from manual configurations to an automated IaC model. The article also discusses lessons learned from their journey, including the importance of automation and proactive governance to minimize configuration errors and enhance engineering velocity.

Key Learnings

• 1Implementing Infrastructure as Code (IaC) allows for consistent and secure management of configurations across multiple accounts.
• 2Shifting security checks to earlier stages in the development lifecycle helps identify issues before deployment, reducing the risk of incidents.
• 3Using Policy as Code ensures that security requirements are enforced automatically, minimizing the need for manual audits.
• 4Automation tools like Terraform and custom CI/CD pipelines can significantly enhance operational efficiency and reduce human error.
• 5Establishing a strong internal community for knowledge sharing can facilitate smoother transitions to new technologies and practices.
