Oracle have a great free tier. For free (not a trial, but forever free), you can get a virtual machine with 24gb RAM, and storage of 200gb. you might wanna consider that.

If you do choose to use oracle, I’ll note you that you do need a credit card, tho it’ll not be charged unless you manually upgrade your account to paid account.

I’m not advertising them, I just really think they’re great and I’m using it myself.

I’ve been at Contabo for years before moving my server home, was always happy with them. Just for something like Nextcloud you want a lot of storage space which gets expensive fast with a VPS…

Linode, Digital Ocean. I’ve worked with both in the past, but that was years ago so I don’t know how things are now.

If all you want is Nextcloud, you are probably better off getting a managed service like this: https://www.hetzner.com/storage/storage-share/
