You get a generic VPS and you can do whatever the hell you like, not paying bigG for some "obvious reasons" like outbound traffic.
And a small business will never need 5 nines availability, that's just the propaganda from big tech to over engineer and pay them for that. You can run a small/medium business and be offline for 1 hour every day (makes it 95.8%) and still be fine. It's when you're worldwide and not that small that you want better availability.
Also, you know all those AWS outages? My VPSs were never impacted to the slightest!
