You switch vendors after instrumenting with OTel. What changes?
- AThe exporter configuration — the instrumentation itself stays put
- BEvery call site — the instrumentation names the vendor
- CThe whole SDK — each vendor ships its own implementation
- DNothing at all — a vendor reads OTLP straight from the application
Why this is the answer
Vendor neutrality is the point of OTel: code is written against its API, so swapping backends means pointing the exporter (or the Collector) somewhere new. Call sites never name a vendor, the SDK is the upstream implementation rather than a per-vendor one, and something still has to be told where to send the data.
