In previous blog posts, my colleagues and I have introduced and explored the Calico eBPF data plane in detail, including learning how to validate that it is configured and running correctly. If you have the time, those are still a great read; you could dive in with the Calico eBPF Data Plane Deep-Dive.

Amazon’s custom-built Graviton processor allows users to create ARM instances in the AWS public cloud, and Rancher K3s is an excellent way to run Kubernetes in these instances. By allowing a lightweight implementation of Kubernetes optimized for ARM with a single binary, K3s simplifies the cluster initialization process down to executing a simple command.
