Can I set a hard limit to Google Cloud Platform spend? if yes, how?

Question

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.

Answer 1

It is possible to cap costs and stop usage for a Google Cloud project. You need to

• setup up a budget to monitor project costs,
• enable budget notifications
• and then configure a Cloud Function to call the Cloud Billing API that disables billing for the project as described in GCP documentation.

Answer 2

There isnt ~currently~ a way to centrally cap spending on most of the functionality in GCP - its been mentioned a few times on https://googlecloudplatform.uservoice.com/ and they do seem to be putting some work in on this side of things.

You can get alerted via this though https://cloud.google.com/billing/docs/how-to/budgets
