The Lightweight Cloud Servers War Begins
summary
Claims that CoreOS, Atomic Host, Snappy Ubuntu and VMWare Photon replace RPM/DPKG with transactional image updates that can roll back; they compose common components like etcd + fleet / Kubernetes and cloud-init for service discovery and provisioning; Atomic uses rpm-ostree to build layered OS images, CoreOS forbids host package installs (uses a toolbox), RancherOS is ultra‑minimal and runs Docker inside Docker, and Photon is a Fedora‑based tech preview — many projects already run and interoperate, security relies on SELinux/AppArmor.
