Costs and general complexity. It is quite easy to accidentally reduce a system's uptime by introducing extra complexity involved with higher availability

  Oh yeah, there are definitely additional costs and complexity involved. Im just saying that these cloud service providers offering managed services should be covering all that - they certainly charge as if they do! And in the case of heroku - and their specific architecture - it is not that complex. Im aware that other cases may vary.

    No particular love for Heroku, but you can pay for multi az failover if you want it. https://devcenter.heroku.com/articles/heroku-postgres-ha https://devcenter.heroku.com/articles/heroku-postgres-ha If you don’t pay you won’t get the feature. Given that multi az failover directly impacts their cost that seems pretty fair.

      Yeah, I suppose in some circumstances their offering is OK. I don't think i have ever worked on a system where 10 mins of data loss is anywhere near acceptable though. I guess for mostly static pages, or self hosting a blog its ok, although id be pissed if i had to rewrite an article. Makes you wonder who their target market is.
