Hosted on Cloudflare

This website lives in the cloud.

No computer at home is running it. The page is delivered from Cloudflare's global network, and the live panel below is answered by a serverless function that only starts when someone asks for it.

What is cloud computing?

Cloud computing means renting computing power, storage and software over the internet instead of buying and running your own hardware. You pay for what you use, or, like this site, use a free tier.

IaaS

Infrastructure as a Service

You rent virtual machines, networks and disks. Example: Azure Virtual Machines.

PaaS

Platform as a Service

You upload your code and the provider runs it. Example: Cloudflare Pages, which hosts this page.

SaaS

Software as a Service

You simply use finished software in the browser. Example: Microsoft 365, Gmail.

Serverless

Functions as a Service

Code runs only when it's called. Example: Cloudflare Workers, which powers the live panel.
