TL;DR: I used the K6 load testing framework to benchmark the Compute Engine f1-micro and Caddy web server hosting this site. With Cloudflare caching turned off, the server was able to serve an onslaught of 800 virtual users continuously reloading the page (while maintaining a median request duration of <400ms), but started dropping requests when increasing the load further.

This is fine.

TL;DR: Azure and Digital Ocean don’t charge for the compute resources used for the control plane, making AKS and DO the cheapest for running many, smaller clusters. For running fewer, larger clusters GKE is the most affordable option. Also, running on spot/preemptible/low-priority nodes or long-term committed nodes makes a massive impact across all of the platforms.
