The minute gens/solar/wind/batteries combo becomes less expensive than public utility I'll switch. For now it makes no financial sense.
With the clouds it is the other way around. My dedicated servers running my software kick the shit out of AWS performance wise for a fraction of the price. And no I do not spend my days "managing" it. I can order new dedicated server and the same shell script will reinstall all prerequisites, restore data from backup and run it in few minutes add (however long it takes to import database from backup). Where needed I also have standby up to date servers.
Other than running this script to test restoration once a month my management overhead is zero.
See... anyone can pick <random thing>, and describe how people don't do it. Of course, you cite a generator, others use solar cells, right?
Looks like sensible/nonsensical based on who you are and what are your needs. Not everybody needs cloud, not everybody can self host.
Yes.
The opposite is also true though: Imagine not wanting to pay for that and needing it!
There's a reason why most homes connect to the power utility companies. Yes, we can run generators ourselves. Does it make sense to do that? Not usually.
Same thing with this server. If it makes sense for your use-case, outstanding. In many cases, people are better off offloading this to another company and focusing on their strengths.
