This document summarizes a presentation about Arm and multi-architecture Kubernetes. It discusses the history and trends driving Arm, including sustainability and the end of Moore's law. It outlines the Arm ecosystem and how Arm CPUs provide power efficiency, performance, and customizability. It notes that Arm is now in all major clouds and everywhere. The goal of multi-arch infrastructure is allowing workloads to run on the best hardware without developers considering architecture. Running Kubernetes on Arm provided better performance, lower costs, and significant power savings. The main reasons for using Arm infrastructure are cost savings of 20-40%, and that Arm is crossing the chasm in adoption.
