If you put several of these ultra cheap VPS behind something like Cloudflare, doesn't that mostly solve the problem with them being down every now and then?

- tomxor 4y agoSure, if it's simple to horizontally scale your service. But unless it's a simple static site it's usually not, and it's usually a source of a lot of complexity and pain. Which unless you really are doing something twitter scale, is not worth it. By the time you've bought a handful of tiny VPSs and put in the work to horizontally scale your service, you could have put the same money with zero effort into a very reliable dedicated server. Spend the effort elsewhere and save your sanity (and probably improve your reliability). Yes I'm biased against horizontal scaling.

- _cenw 4y agoCloudflare isn't going to do load balancing for free, neither do most VPS providers (if at all), and you're likely making some network admin angry trying to run something like keepalived, but it sure is true that building your systems to be fault tolerant comes with the option of using cheaper "base resources".
