> I beg to differ. > In my experience, the complicated setups that are justified by the argument of "reliability" have more downtime then a single VPS. The reason is probably that there are more moving parts and more has to be maintained / can go wrong. > These days, a single VPS in the right datacenter has excellent uptime. Again, maybe in your experience but that's not universal. There's literally no redundancy with running everything off a single VPS and if that datacenter has network or hardware problems, then your service is down. Is redundancy necessary for the scale of OP's app considering it provides 0 income? Most likely not, but that's a decision they've decided on and there's nothing wrong with that. What does excellent uptime mean in your book? With Digital Ocean's AM2 region I had regular downtime every few weeks and while I'm alright with it, if I had another VPS in another datacenter it would've had next to no effect on the customer experience. But an hour or more of downtime every two weeks isn't excellent.
