And then there was k8s
summary
Presents a historical lineage from IBM OS/360 through virtual machines (KVM, Xen, VMware, Hyper‑V) and Linux kernel features (cgroups, namespaces, overlayfs, btrfs, zfs) to Docker (dotCloud) and Kubernetes. Argues that cloud evolution relied on efficient virtualization hardware, that Kubernetes drew on Borg/Omega ideas, became a practical standard for deployment and lifecycle (GKE in Nov 2014, on‑prem in Apr 2015) and by mid‑2018 had widespread managed offerings, exposing operations consistently via kubectl.
