It's been one year since Action Cable debuted at RailsConf 2015, and Sophie DeBenedetto is here to answer the question in the minds of many developers: what is it really like to implement "the highlight of Rails 5"?

Deployment That Just Works

Last week I talked a bit about why instant deployment matters . A few people have since commented that it’s not instant deployment that matters to them, but rather deployment that just works every time.

Of course, what we’re really talking about is both. Part of achieving deployment that just works is decreasing complexity and removing steps – each a point of possible failure. We are working toward deployment that’s both instant and completely reliable, because we think those things are tightly linked.

We’ve rolled out some new content today explaining more about how our platform works , including some more detailed…
