Observability Summit North America 2026

Enterprises often struggle with the "black box" nature of proprietary APM tools and the high cost of distributed tracing at scale. In this session, we will demonstrate how Comcast tackled this challenge by migrating 350 critical applications from AppDynamics to a cloud-native OpenTelemetry (OTel) stack, achieving a truly unified end-to-end observability experience.

We will pull back the curtain on the architecture that powers this migration. Specifically, we will show how we leveraged the OpenTelemetry Collector to generate Request, Error, and Duration (R.E.D.) metrics from trace data using the SpanMetrics connector. A key highlight will be our unique deployment of Conduit, which serves as a resilient transport layer to ensure data integrity and effective load balancing in a high-volume environment.

Attendees will leave with a blueprint for breaking free from APM vendor lock-in. To help the community fast-track this transition, we will also be sharing and walking through our reusable, battle-tested Grafana dashboards that can be leveraged by any enterprise.
