High Availability at Heroku

YOW! 2012 Sydney

This presentation discusses high availability at Heroku, the cloud application platform. We motivate the discussion with specific examples from our experience designing, developing, and operating highly available cloud services at scale. We emphasize that high availability depends critically on the interaction between development and operations, and highlight several patterns that we’ve found useful in our systems work at Heroku.
