Especially in combination with content addressed file systems like IPFS (which gives you additional features like built-in checksums, immutability, de-duplication and storage resilience) you can have a Deno instance running and as the deployment step simply send it a file hash or URL to execute (of course with the appropriate security precautions like a signature or encryption on top). I built a prototype to see how it could work and a full Deno app deployment to my own VPS took less than 2 seconds. No git pushes, no container build pipelines, no proprietary cloud services.
