I agree about being too scared to do business with Google. FWIW, I have a project that monitors an AWS S3 hosted web site every minute and takes it down if the charges exceed a quota. It ends up costing me 44 cents a month to run it as a lambda function but I think of it as insurance. Pull requests are welcome from whoever understands Terraform better than me because I couldn't figure out how to automate everything about the deployment.
