Cloudflare-First Networking as Code with Pulumi

Platform teams managing multi-cloud applications often face significant challenges due to visibility gaps between tightly controlled origin infrastructure and the manually adjusted configurations at the network edge. Such discrepancies can lead to application vulnerabilities and routing failures that often go unnoticed until users report issues. Given that the edge serves as a critical layer for enforcing security and traffic policies across multiple clouds, the text highlights the risks of relying on manual adjustments, which can introduce security holes and performance bottlenecks. It proposes the use of a standardized Cloudflare edge baseline, implemented with Pulumi, to define DNS records, custom WAF rules, edge logic canaries, and Zero Trust Access policies, ensuring a version-controlled, reliable, and secure edge environment that aligns with application code. The text also provides detailed instructions for setting up and validating this baseline, emphasizing the importance of maintaining security consistency and reducing manual configuration drift.
