Mmm yes, this one reminds me of the microservices debacle from a few years ago about when does your monolith technically become a microservice. I can't find the link, but I think we were unable to clearly define at which point your monolith has become a true 'SoA' group of microservices.
The generous interpretation of what op said is that you don’t have to maintain a server in any way or shape which is indeed the case. You only write business logic while the infrastructure automatically connects it to handle inbound requests.
