Kubernetes has become the go-to platform for deploying applications in recent years. And while it offers a multitude of impressive features, it also comes with a set of responsibilities and potential challenges – specifically around running scalable and resilient workloads without losing track of costs.
In this Observability Clinic with Andreas Grabner @andreas_grabner we have Henrik Rexed @@HenrikRexed, Cloud Native Advocate at Dynatrace and host of IsItObservable, giving us insights with live demos on:
Measuring the Cloud Costs of your K8s Clusters
The Impact of non-optimized K8s resource allocations
The latest K8s features in Dynatrace
How to leverage HPA (Horizontal Pod Autoscaler) with any metric from Dynatrace
Henrik also educates on how to best observe and monitor your K8s workloads, covers essential metric best practices, and how to identify side effects of improper auto-scaling.
