This document summarizes the transformation of Comcast's infrastructure and development processes using cloud metrics and open source tools. It discusses moving to a cloud-native approach using Cloud Foundry, consolidating monitoring tools including InfluxData, and partnering with development teams. This enabled transparency into infrastructure and application metrics, identified efficiencies, and helped deliver products faster while removing heavy lifting for developers. The results included supporting over 2,000 developers and 1,000 unique applications on a significantly larger cloud infrastructure.
