Things like automatic failover and high availability in general are cool, but your SLOs should be set according to your business model, e.g. they need to make business sense.
I do understand how people like VPSs at $5 or $10/month (I've used one like that myself for years), and I do understand why companies that need massive scalability use AWS. But I do not understand why people in the middle (which I think includes a significant fraction of this audience) assume that a provider like AWS is the best solution.
Anyway, those are just my thoughts. I've been running a business on Hetzner servers for years now. And this is not necessarily a recommendation to use Hetzner: there are many providers which will offer low-cost physical servers. I think in spite of the cloud hype, these make sense for many applications.
