Adopting OpenTelemetry does not have to be hard for common use-cases. On Kubernetes, the Dash0 operator (https://artifacthub.io/packages/search?repo=dash0-operator) automatically instruments Node.js and Java workloads (and soon other runtimes) with just a custom resource created in a namespace. It works with all OpenTelemetry backends I know of.

Disclaimer: I am one of the authors of the Dash0 operator and work on Dash0 (https://www.dash0.com/), an OpenTelemetry-native observability platform.

Automatic instrumentation on Kubernetes is also provided by the community OpenTelemetry (https://github.com/open-telemetry/opentelemetry-operator).

I am certainly biased here because OpenTelemetry and Prometheus have been at the core of my professional life for the past half decade, but I think that the biggest challenge, is that there are many different ways to get you to a good setup, and people get lost in the discovery of the available options.
