Setting Up Cost Control with Quota
On my first attempt it appears that the quota changes did not take effect, therefore the quota was not exceeded. I tried correcting that, but even after receiving the error message I could not get to 100% completion. Why not keep it simple and just change the quota on VMs in a specific region? BigQuery is perhaps overly complicated (adjust cache, etc.) when just trying to teach someone about the concept of quotas.
It seems I'd done everything right in the first time, but it hadn't worked. In the second time, I don't know what changed, but it worked.
