Run Ordinary Rails Apps Globally (2021)
Alas, I feel like the word &quot;Ordinary&quot; is doing a lot of heavy lifting in this title!<p>The upshot is, so long as your postgres + rails app isn&#x27;t doing some kind of DB write with every request, and doesn&#x27;t do much - or ideally anything -  with Redis, and you want 200ms time-to-first-byte globally (or at least, in multiple locations across the world) then you can easily get better performance with Fly.io than most other solutions.<p>It&#x27;s a really clever solution, and one day I&#x27;d love to work on a project that fulfils all of those constraints. Haven&#x27;t found one yet though.
