Someone else has a server and their infrastructure is set up so you can upload a zip of some executable and they’ll figure out how to make it run. You don’t worry about any details except your code and whatever API is require to be compatible, and they worry about hosting it, making sure it has memory, CPU time, disk space, DB, etc.
So it’s essentially the same as shared web hosting, just masquerading as a new concept. 15 years ago I’d deploy PHP sites by uploading them via FTP to some free web hosting company.

Except it’s not quite shared but “containerized”
Yep. But you pay only for the CPU time you use and very often the only IO you can do is HTTP due to the runtime.
