All cloud providers will support budget notifications. That doesn’t do much good when you shoot past the budget in a short timespan. I set a Google cloud budget of $20/month and enabled a Tensorboard instance, which had no observable indication that it cost anything except the base cost of the VM, and got notified that I was $280 over budget the next day. Apparently there was an upfront $300/month/user fee for Tensorboard. (Several months later they changed the pricing model to $10 GiB/month with no user fee.)
