For the past year I held the unelected position of “Cloud Cost Czar.” I have written about the duties such a role entails in A Day in the Life of a Cloud Cost Czar. Recently I handed over the cost czar responsibility to a colleague who will carry on the daily routines and continue to improve our cloud cost management endeavors. In the handoff process, almost a year to the day of assuming the czar’s responsibilities, I reflected on the previous twelve months and all the accomplishments the company made as a united team to “tame the cloud.”
I created a graph to visualize the dramatic change over one calendar year. To the right is an area graph that shows subscriber seats (in green) overlaid on subscriber costs (blue, orange and red; our principle costs are cloud compute and two types of cloud storage.) As subscriber growth increased, costs went up, peaked, and then went down over the course of one year. The rise, peak, and subsequent decline all map to various cost cutting efforts initiated by Sonian engineering and support groups.
Throughout the year we got smarter on how to “purchase” compute time for less than retail, how to store more customer data while consuming less cloud storage, and how to process more customer data using fewer CPU hours. In the cloud, we re-affirmed with a high-five on each improvement, we were in control of our cost destiny. This is when the phrase “infrastructure as code” really means something.
