OpenTracing and OpenTelemetry primarily operate in which layer of a software system?

• A. Infrastructure
• B. Application
• C. Networking
• D. Data plane

Answer: (B)

OpenTracing and OpenTelemetry are about instrumenting the code itself to produce telemetry data as a program runs. They provide APIs and libraries you embed in your application to create spans around operations and to propagate trace context as requests move between services. Because this instrumentation lives inside the application code and follows the flow of a request through your services, it operates at the application layer. It’s not about configuring infrastructure, networking hardware, or data forwarding paths, which would be the realm of infrastructure, networking, or data plane concerns. By instrumenting the application, you get distributed traces and metrics that originate in your code and travel across service boundaries to observability backends.
