Blaming in a Blameless World

Attribution of reliability in a microservice architecture can be solved, and has been solved, in very different ways due to how services are cataloged across the industry. Our hypothesis at Lyft was that service catalogs can become stale, but ownership derived from an on-call rotation will be significantly more reliable for attribution. We’d like to share our journey through combining Envoy, Pagerduty, and an organizational hierarchy to identify reliability concerns across Lyft through standardized SLOs and Director-level rollups.
