Observable Event-Driven Autoscaling with KEDA, OpenTelemetry, and Dash0
Blog post from Dash0
KEDA (Kubernetes Event-Driven Autoscaling) enhances Kubernetes by allowing workloads to scale based on events and external signals, beyond the traditional metrics like CPU and memory used by the Horizontal Pod Autoscaler (HPA). By integrating with OpenTelemetry and Dash0, users can gain insights into KEDA's internal metrics, improving observability and enabling more efficient workload autoscaling. KEDA operates by monitoring defined triggers and adjusting workload replicas accordingly, even scaling down to zero when no work is pending—a feature the HPA alone cannot achieve. The integration with OpenTelemetry offers visibility into KEDA's decision-making processes, allowing users to diagnose scaling issues effectively. Additionally, KEDA's capability to scale based on various event sources, such as message queues and scheduled events, makes it a versatile tool for managing dynamic workloads. With Dash0, these metrics become accessible and actionable, providing a comprehensive solution for event-driven scaling in Kubernetes environments.
