This works, I can confirm as of Dec 2022. The signup process is a bit maddening, as is the way of Oracle, but the service is legit. Does require a CC# to get going, but the service is using the free tier. I have not been charged.
The future is cloud based computing for sure. Some of us sticks in the mud will still roll our own, but even then you will likely need a cloud based computer. Might as well get on board.
The Oracle platform offers a few operating systems including Ubuntu. One would be hard pressed to find a linux distribution with more community support than Ubuntu (which is Debian based), and it is really easy to use for general computing needs while still being a full linux box with direct Internet access. Host your own sites, wp blog or application if you want, or just use it as a access anywhere desktop. No charge.
