At Kinsta, we’re obsessed with speed: Our Application Hosting, Database Hosting, and Managed WordPress Hosting services all run on the Google Cloud Platform’s fastest Premium Tier Network and C2 Machines, and we rely on Cloudflare to keep the pedal to the metal for tens of thousands of customers who want to deliver their content around the world with speed and security.
While making that happen, we’ve learned a thing or two about using Cloudflare Workers and Workers KV to provide optimized caching rules for static and dynamic content.
In early 2023, we doubled down on Cloudflare cache wrangling, making caches more responsive to client-side configuration changes while also shifting the heavy lifting behind broadcasting feature updates away from our admins on the backend and into Cloudflare Workers. A key result was a dramatic increase in the share of customer data successfully cached, increasing 56.3% between October 2022 and March 2023.
