Efficient Kubernetes scaling using Karpenter
2023-02-06, 16:45–17:35, C.1.155

Kubernetes doesn’t come with a built-in node autoscaling out of the box and as many other things it leaves it to the platform team to implement the appropriate strategy. Efficient node autoscaling is essential for ensuring that Kubernetes clusters can handle dynamic workloads and environments. In this talk, I will cover how Karpenter (an open-source node provisioning project) can be used to automate and manage Kubernetes nodes lifecycle by trying to make smarter decisions when it comes to right sizing your compute. It should result in improved resource utilization, reduced costs, and the ability to quickly and easily scale up or down based on workload demands compared to similar battle tested solutions. So does this really addresses all the scaling problems, what are still the gaps and how does it work in practice? I’ll also run a live demo to show how to use it and what to expect.
