Zero downtime deploys for Rails apps - slides

Here are the slides for my talk on zero downtime deploys for Rails applications, presented at RailsConf 2012.

Really glad I had the opportunity to present here; hoping this will get people motivated to start thinking about the topic, and change the way we address the issues described there.

Reference:

• Asset Resource
• Table migrator - Rails 2 plugin to migrate MySQL databases without downtime
• Random benchmark of schema migrations both in MySQL and Postgres
• The pull request bringing assets:clean:outdated into Rails
• Nuts & Bolts: Good intro to HAproxy

This was obviously heavily inspired by two blog posts I wrote in the past:

• Hot compatibility beyond databases
• Rails migrations with no downtime
