Yes, and i'm not cheap. I have 2 HA clusters with 2 different providers, with sync and failover between the 2 sites. I also have DO as an emergency fallback / overflow. I manage and maintain everything for our clients. My cost is about $500 per month for 6 machines in total, 16CPU/64GB RAM/25TB SDD per machine.

My minimum monthly charge for hosting a site is $150 for a simple site, $300 for something more complex, and most of my clients are at $500. This includes 1/2/3 hours support/site changes respectively, and dealing with security, patching, speed, uptime etc.

If you can build something like above and keep it running, it is a nice money-maker.
