I’m using IPS now. Before that, I managed my own AWS instances and before that, I had a VPS from KnownHost.
I moved my site to IPS as I was tired of worrying about managing servers, etc. It was also part of ensuring the site survival. Most of the people in my site’s community know nothing about hosting accounts or servers or what it takes to keep a site online. By having IPS take care of software and hosting, if something happens to me, one of the other admins can take over the bill and just keep running the site as it is today without needing to learn a bunch of new stuff.
