A Linux distribution that updates itself. That’s the idea behind the new commercial Linux product from CoreOS, called CoreOS Managed Linux.The service will begin at $100 a month for up to 10 servers, and, as co-founder and CEO Alex Polvi told news media, enterprise users should think of the new service “as the last migration they will ever need.” As with other open-source companies that provide additions and services around open-source software , the CoreOS fee is intended to cover fixes, updates and tech support, not the free core software. CoreOS runs from the cloud or can be managed on-premises.

CoreOS is a fork of Chrome OS, using it as a base while adding new functionality and customizing it to support hardware used in servers. As of February 2014, CoreOS is actively developed, primarily by Alex Polvi, Brandon Philips and Michael Marineau.

CoreOS provides no package manager, requiring all applications to run inside their containers, using Docker and its underlying Linux Containers (LXC) operating system–level virtualization technology for running multiple isolated Linux systems (containers) on a single control host (CoreOS instance).
