But the article starts with "I run a Dokku server on a $7/month VPS", so author meant something else (probably just wrong usage). Maybe Dokku has 2 modes, where you can launch it on classic server (fixed price per month) or deploy on pay-as-you-use platform (https://www.cloudflare.com/learning/serverless/what-is-serve...). Calling something serverless without trying it first is deceiving.
