almalino Lightsail has all mandatory bare bones for EC2/RDS = easy server start with multiple OSes, elastic IP, snapshots, SSH etc. It is more than enough to host Flarum.

It's like docker-compose then, but without the files and just a ux for easier management? Thanks for the clarification.

    luceos It is sounds like docker compose but at the end of the day you get virtual EC2 Linux server where you can do whatever you want. You have full access rights to it. And UI allow to attach IP/Domain to it and make snapshots/recover/reboot

    I do most of the stuff by SSH to the EC2 instance on lightsail.
