Rude tone apart, this is absolutely true. Nobody thinks satellite Internet is meant to compete with fiber to the door.

Is that an issue with the format or the currently available tools though?

Fdroid is a secure repositorie and the applications are reviewed before being made available for end users.

Reviewed by who though? Malicious apps even get through apple and Google’s screening. I can’t see how fdroid can match the capabilities of those guys.

Any brands you would recommend?

I’m curious which part you think is overkill and how you would redo this? I have a proxmox cluster and run docker amongst other things, but haven’t set up any sort of high availability.

I don’t need live migrations, but something that could help with load balancing and reducing any potential downtime if a host fails would be great.
