Many teams unknowingly introduce observability vendor lock-in by instrumenting apps directly for Prometheus, Elasticsearch, or others.
In this hands-on article, I walk through how to solve this using OpenTelemetry — a vendor-neutral standard for metrics, logs, and traces. You'll learn:
- The cost of vendor lock-in (with working Prometheus/Elasticsearch examples)
- How OpenTelemetry simplifies observability architecture
- Step-by-step setup using Docker and Python
- Easily switching backends from Elasticsearch to Prometheus (without code change)
