I currently have a small problem that I would like to solve. My small mail server is on the free tier of Oracle Cloud. I would like to set a PTR, but need access to support for it... so Pay as you Go.
Now I would like to avoid additional costs though, as it is just a small hobby project. I don't get along with the metrics of the cloud. Partly I see negative transfer rates and the like.
Could someone explain me a way how my ARM server shuts down automatically... should it ever reach the free 10TB due to an attack or misconfiguration. Would love to switch to the pay version with a safety net to reach support, but just not much more.
Thanks in advance for your help
