You say that the question you intended to ask was "How is it possible to set up a server that runs less than 24 hours a day?". It's not my job to speak for the community, but my gut feeling is that such a question would be on-topic for SF (I definitely have a concrete answer for it, since I do that very thing quite a lot).
To my mind, the problem is that your original question only asks that as a rhetorical flourish ("How does one even do that?"), and it asks a lot of other stuff that, at least to my mind, is definitely off-topic. This is because most of it relates to a commercial entity's billing practices and the oddities of Google Cloud's billing calculator (is not about ... working with a service provider's management interface)
In this specific case, if I were you, I'd delete my original question (before it accumulates any more close votes or downvotes) and ask a new, tightly-focussed one.
