If you’re lucky enough to successfully create an account on Oracle Cloud, you can also try Oracle Cloud Free Tier. You can have free ARM64 x4 CPU and 24 GiB RAM totally free of charge. There might be problems with availability during VM registration, but there are scripts that automate spamming for checking every 80 seconds.
I’ve been using it for 2 years and it’s great. However be aware that your VM might get erased if you have a free account. That too can be remedied if you update to a premium subscription (You still get Free Tier resources without a charge). Nobody has reported an erased VM on a premium plan yet.
Still, I am pretty sure they can erase it if you do illegal stuff with it. I’ve been using it only to host Minecraft Server, as well as other services using Docker. So far so good.
