The American Express mobile apps support many customer journeys, in many different markets, implemented by many disparate developer teams. That complexity makes it extremely difficult to develop consistent instrumentation throughout the applications. After testing out numerous tools, none of which seemed to fit right, the Mobile SRE team reframed the problem—focusing on the developer perspective— and developed an event-based telemetry pattern that greatly reduces the cognitive load on developers during instrumentation implementation. This talk will show how the Mobile SRE team rearchitected their instrumentation platform in a way that allows feature developers to communicate their business logic, without having to be an expert in any particular instrumentation technology. The team will demonstrate how an event framework can be placed in front of a framework like OpenTelemetry to streamline development. And finally, we’ll present how our codebases became cleaner, easier to reason about, and more testable as a result of this pattern.
