I don't understand why it should be called "serverless" when using cloud infrastructure. Fundamentally you're still creating software following a client-server model, and expecting a server to run somewhere so that your users' clients work.
To me, "serverless" is when the end user downloads the software, and thereafter does not require an Internet connection to use it. Or at the very least, if the software uses an Internet connection, it's not to send data to a specific place, under the developer's control, for the purpose of making the software system function as advertised.
