I do not think so. What you are talking about is managed hosting, not cloud.

Cloud means the providers are running their code, not yours. In most cases
they will not share it and you are lucky if they allow selected partners to
access their proprietary API. Anybody who wants to provide a similar service
can start programming it from scratch.

If you just want to build a HA-pair of 2 devices: It does not help you much.
Your next single point of failure is your internet connection. The next is
other people kidnapping your devices. You also have to deal with stuff like
the split-brain problem. A better may would be a P2P network which can cache
your content, like GNUnet does. But this requires every client to support the
protocol. While certainly desireable, I do not think this is feasible. That is
unless you do not mind having many people who are unable to access your
