Episode notes
Vendor-Neutral Observability Standard
- OpenTelemetry creates a vendor-neutral standard for metrics, logs, and traces that lets you instrument once and change backends later.
- That standard reduces vendor lock-in and increases optionality for teams and observability providers.
Keep Vendor SDKs Out Of Business Logic
- Use OpenTelemetry as an abstraction layer to avoid sprinkling vendor SDK calls through your business logic.
- Instrument with Otel and inject vendor exporters at the collector or DI layer to keep code portable.
Otel's Rapid Cloud-Native Adoption
- OpenTelemetry is the second most popular Cloud Native Foundation project after Kubernetes, showing rapid adoption.
- Its rise reflects industry consensus that a common observability standard was needed.
