I using this from start when this is all free. Okay, it´s free, but these mobile processors horrible. And not all software working (like in aaPanel can´t install OpenLiteSpeed, Mailserver and so on...). Best panel for this is Hestia.
With MasterCard you can register without problems.
I have 3 free Oracle accounts and you can use it like Remote Desktop:
In the video don´t see how secure the RDP port with Fail2ban and most time the Remote Desktop is very slow (get auto-attacked with bots what trying to login).
For webhosting is not much good, like few WP sites without loads(4 arm core). The 2x1/8 core x86 running OpenLiteSpeed and anything, but power from 1/8 core is not too much... Think for it like other FREE webhosting services.
SMTP is TOTALLY BLOCKED, no 1 email can go out (all people spamming). Only when you pay can get STMP (but you can set external SMTP for own use like Mailgun, Mailjet...).
VPN very fast forget, big companies like Amazon prime, Netflix, Google knows the Oracle IP addresses, nonstop blocked or Google captcha "are you human?" pictures (not only checkbox).
You can get 1 dedicated IP address, others IP can changed anytime. Few months ago get Oracle a big hardware failure:
And you can´t access the 2 VPS from 3... Must add a new IP for instances.
A good tip: Before create choose
Ubuntu version and SSD boot set to free
200GB (automatically is set to only 50GB pieces when you click next).
Beware of not overuse, I only use 4 core and 20GB ram. My friend used 6 core (in 30 day trial is okay, you get free credits) but after 30 days Oracle delete all your instances over limit, or get charging 0,06 cents every hour or so...
