I provided my credit card for the trial. I was notified of the impending end of the trial, and was billed no further.
I do agree that the inability to set hard limits on usage is frustrating and somewhat concerning, however. Especially as they're apparently able to do so through the aforementioned trial termination mechanism.
And I further agree that, outside of this trial period, this policy does discourage experimentation. And that it is somewhat un-Google-like; somewhat surprising as I believe they're considered an underdog relative to AWS; and a bit disappointing.
I think that's ridiculous. It should deal-breaker problem for anyone running on a side project.
What has become abundantly clear however is that CC gating is a fast way to reduce your malicious traffic _exponentially_; and especially if you're enterprise focused, this doesn't even impact your core strata much.
As a non-corporate-techie in my off-work-time, I absolutely understand the frustration at this inflexibility. During my day job where I'd have to clean up the fires that result from a fully open door policy however? I'd have a somewhat different take.
It's not 100% clear cut "the CC is all just to add spurious friction", is all I mean to say :)
I totally can't tell how much this could cost me; I'm pretty sure I'm still under the free quota limit, but I can't see how far I'm into it. I see that there are requests being logged in the API metrics, but the billings pages show 0 usage across all the same metrics.
You would not be charged more but then would maybe be in breach of the contract passed with Google (?)
We're here to help on that one. :) We strongly believe development and educational use should be painless, so testing locally (just use the right link!) or signing up for the free tier is as simple as possible.
E.g. I'd put up an experimental site which uses google maps free qouta only and I don't want to pay anything, since it's only an experiment, I'd be happy with my access blocked automatically for the rest of the month after the free quota is exhausted.
But AFAIK it cannot be done. You have to track you spendings and shut down the site manually when you are near the end of the free quota.
Google in the past helped people experimenting with its platform. This is not the case anymore with google maps.
