I want to know if there are any good solutions for autoscaling dynos AND workers on Heroku in a production environment (probably a different solution for each of those, as they are pretty unrelated). What are you/companies using, regarding this?
I found lots of options, but none of them seem really mature for a production environment. There is Heroscale, which seem to introduce some latency as it does not run locally, and I also heard of some downtime. There are modifications of delayed_jobs, which have not been updated for a long time, and there are some issues with current bundlers. There is also some alternatives related to reque, which seem not to handle very well some HTTP exceptions, which results in app crashing, and others which seem to need an always-running worker to schedule other workers, and may also suffer from some HTTP exceptions problems.
Well. In the end. What is being used, nowadays, for autoscaling Heroku's dynos and workers on a production environment with Rails3?
Thanks in advance.
