on the one hand, hosting is hard, you should pay people to host, especially distributed systems.

on the other hand, deno land folks stole from (used open source from) the best. the coordination layer/control-plane is all S3 CAS of dumb json files, which is a fantastic common-mode infra requirement for most orgs anyways, & perhaps a durable control-plane substrate you'd feel comfortable having someone else run (such as aws or others), while you run the data-plane (workers) yourself. and then for the durable objects themselves, they used litestream, which is a pretty top pick, excellent way to get radical distribution (but actual topology not included, some assembly required)! https://hn.algolia.com/?q=litestream

there's no reason this wouldn't run fine on most hosting, you definitely don't need bare metal. the virtues of v8 sandboxing / isolates! no need for vm's at all, no nested vm difficulties if you are trying to host on a shared host! but if you're asking questions like this, i want to again point you back to my top point.
