Autoscaling Your Kubernetes Apps with Dash0: Beyond CPU and Memory
This blog post demonstrates how to leverage Dash0 for automated scaling of Kubernetes applications. While Kubernetes simplifies scaling, manual replica adjustments are inefficient. Dash0 automates this process by monitoring application telemetry. The post explores three Kubernetes autoscaling types: Horizontal Pod Autoscaling, Vertical Pod Autoscaling, and Cluster Autoscaling, focusing on Horizontal Pod Autoscaling. It explains its mechanics and how to utilize custom metrics (like latency) instead of solely relying on CPU and memory utilization for optimal scaling strategies. Dash0 integrates with the Prometheus Adapter, enabling PromQL queries against Dash0 data to drive HPA, resulting in automated scaling based on application performance and improved user experience.
