<strong>Shifting left at enterprise scale: how we manage Cloudflare with Infrastructure as Code (7 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Cloudflare transitioned its internal operations to an Infrastructure as Code (IaC) and "shift left" security model, managing hundreds of production accounts with Terraform and a custom CI/CD pipeline. This approach uses the Open Policy Agent (OPA) framework and Rego to define approximately 50 security policies, ensuring automated compliance checks and peer reviews before deployment to minimize human error.

<strong>Logging sucks (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Traditional logs are noisy, low-context, and optimized for writing, not for answering real debugging questions in distributed systems. The fix is wide events (canonical log lines): emit one high-cardinality, high-dimensional, context-rich event per request (with tail sampling). This turns debugging from grep-based archaeology into fast, analytical queries.
