Living without scheduled maintenance

An ignite talk I gave at DevOpsDays Chicago 2014. Here's 4 strategies for avoiding scheduled maintenance.

Note: this is a slight variation from my ignite format, because the chat format is annoying to glance through.

Video of the talk is available on youtube: https://www.youtube.com/watch?v=01Qfk7d8CMg&feature=youtu.be&t=21m36s
