50 Shades of K8s Autoscaling #CDS23

Elasticity and unlimited scalability are the holy grail for any cloud-native application. Now you might think: “That’s easy!!! I just run my containers on a Kubernetes cluster and I am done.” But is it really that simple?

Turns out it’s not! Your application as well as your cloud infrastructure and K8s cluster need to address and support these non-functional requirements.

This session will have a detailed and also practical look at the different ways of autoscaling in Kubernetes. We will give an overview of the technical foundations and prerequisites, and then showcase several frameworks and technologies that can be used to flexibly autoscale your cluster and your cloud-native workloads.
