The price of storage has dropped so precipitously in the last 10 years that ANYONE can have their own personal home cloud. I recommend Synology’s product line. They’re Taiwan-based, but if you strip out the “one-click” and “ease-of-use” stuff, you can set up a decent cloud stack in your home.
The advantage of cloud, as I see it, is not for storage but for compute. I run an enterprise server in my home, to my wife’s chagrin, but it’s not light on the electric bill. I’ve tried to cram as much as I can into the hypervisor, and now I’m fighting resource constraints. I’ve offloaded a couple of minor Linux workloads to Microsoft’s Azure stack, and it handles those loads very well and at a low cost; but there’s always the risk of a memory leak or something similar, and my information is suddenly not so private anymore.
I may hit you up for some advice later in the coming months.
