Zero downtime deploys for Rails apps
Presenter: Pedro Belo
Hailing from Brazil, Pedro moved to the US and A and joined Heroku back in 2008, taking projects ranging from Node.js support to organizing Starcraft nights. Today he works on the API team, focused on making the Heroku public APIs smoother.
What does it take to deploy an application without any downtime?
More than most Ruby developers would expect, turns out; what is aggravated by the lack of documentation and other resources on this topic.
In this talk we'll dive into both development practices (hot compatibility, database migrations, caching) and deployment setup (Heroku, Unicorn, HAProxy), covering everything you need to know in order to ship code without affecting a single customer.
