Scaling capacity while saving cash

There was a very interesting release engineering summit this Monday held in concert with LISA in Seattle.  I was supposed fly there this past weekend so I could give a talk on Monday but late last week I became ill and was unable to go.   Which was very disappointing because the summit looked really great and I was looking forward to meeting the other release engineers and learning about the challenges they face.

Although I didn't have the opportunity to give the talk in person, the slides for it are available on slideshare and my mozilla people account   The talk describes how we scaled our continuous integration infrastructure on AWS to handle double the amount of pushes it handled in early 2013, all while reducing our AWS monthly bill by 2/3.

Cost per push from Oct 2012 until Oct 2014. This does not include costs for on premise equipment. It reflects our monthly AWS bill divided by the number of monthly pushes (commits).  The chart reflects costs from October 2012-2014.

Thank you to Dinah McNutt and the other program committee members for organizing this summit.  I look forward to watching the talks once they are online.
