One of the greatest out of the box features of K8s is its auto-scaling capabilities, which has a naive implementation or more advanced scheduling capabilities through native tooling. However, both of these models are reactive and not proactive in nature. What if we could employ proactive event-driven scaling of our clusters?! Over our many years of cloud native operations at scale, with the right tools we could! Enter KEDA (AKA Kubernetes Event-Driven Autoscaling). KEDA was built to make just this type of intelligent auto-scaling possible - this includes everything from event-driven and predictable actions like scaling up and down for predictable bursts of usage or shutting down dev clusters during specific and non-working hours, to managing scaling based on your workloads and message queues, or even your APMs and based on the metrics it ingests. In this talk we’ll walk through auto-scaling on steroids with KEDA, how it can be supercharged through CRDs, and in particular the cluster-API which now makes it possible to provision, update, customize and delete K8s clusters declaratively––that together are a game changer when it comes to the infinite scale K8s makes possible.
