keda also works for this and supports many backends

I looked into how to wire the Horizontal Pod Autoscaler for Kubernetes to Dash0, the OpenTelemetry-native observability tool I am working on, and it turned out to be surprising simple.

While useful, this is a more fragile autoscaling solution that HPA out of the box. It requires your otel metric to Prometheus pipeline to be up AND your Prometheus server to be up.

Compare that to the vanilla HPA which is entirely cluster local, and “simple”.

Generally the simple approach is the most stable approach.
