That limitation (spinning up an instance) only exists if you don't put a payment card in. If you put a payment card in, it goes away immediately. You don't have to actually pay anything, you can provision the always free resources, but obviously in this regard you have to ensure that you don't accidentally provision something with cost. I used terraform to make my little kube cluster on there and have not had a cost event at all in over 1.5 years. I think at one point I accidentally provisioned a volume or something and it cost me like one cent.
