The article misses one important point about free dynos. After a period of inactivity, your dyno will be come idle. This simply means that the next request will have significantly higher latency as the dyno restarts. This latency becomes even worse if you're waiting for 10 different services to start.
Of course, this isn't a problem if your app gets a reasonable amount of traffic but at that point there's a good chance you're paying for multiple dynos anyway.
- rdegges 12y agoAuthor here -- this is correct. I think it's a pretty good tradeoff though! At OpenCNAM we handled billions of API requests, and some of our internal services actually ran on a single dyno (async stuff, mainly) -- but still, it was pretty awesome.
- michaelmior 12y agoDefinitely if you have sync stuff running on the free tier, you can mostly stop caring about idling :)
