I'd like to make sure I don't spend too much money in GCP (Google Cloud Platform) usage, but I'm not sure of the way to do so, if such a way exist.
So I tried creating budgets in GCP, but I doubt these are hard cap, since the documentation and this question (though asking about google developer console, therefore my question isn't, I think, a duplicate) seem to suggest Google budgets are simply sending notification, but don't put hard cap on your GCP usage.
Thank you for your help.
