That's not what serverless means. It means that your code isn't running on a specific server, and between requests it isn't in any kind of running state whatsoever. It's effectively in cold storage until it's needed, then it's pushed to a frontend/edge server and run. Serverless doesn't mean that there's no servers anywhere, but rather that you don't have a webserver or set of webservers that your code is on; it goes onto a webserver when it's needed, and not before.
