Culturing Resiliency with Data: A Taxonomy of Outages

This talk provides an overview of the categorization of outages that happened in Uber in the past few years based on root cause types. We'll start with some background information, including definitions, incident management framework, and existing preventive techniques, aka best practices. Followed by details and rationale around individual categories, sub-categories, and their relative distribution. Then we'll deep dive into two of the biggest categories: deployment and capacity with a focus on time series based data ming techniques to assist detection and simulation of some of the common root causes. Finally, we'll discuss the propagation of lessons learned in terms of policy and process changes based on these insights.
