Linux Top 3: CoreOS, Oracle Enterprise Linux 7 and Ubuntu 14.10
1) CoreOS Gets Managed
CoreOS is a different type of Linux operating system in that it is purpose built for Docker container virtualization and high-availability. CoreOS leverages a double-buffer approach to system deployment.
CoreOS provides high availability is by including two root file systems as part of a default installation. When a system update is required, the update is first applied to the root file system that is not currently running. Going a step further, CoreOS announced its Managed Linux offering on June 30th, including a feature called CoreUpdate which is a dashboard for full control of rolling updates.
2) Oracle Linux 7
Oracle is now racing forward to release its Enterprise Linux 7 release, which is base on the recently released Red Hat Enterprise Linux (RHEL 7) release. Oracle Linux is currently at its release candidate stage.
While Oracle Linux 7 is based on RHEL 7, there is an optional difference that users can choose. There is the default Linux kernel, which is the same one that Red Hat ships, then there is the Unbreakable Enterprise Kernel Release 3 Update 2, which is actually the default choice.
The Oracle Linux RC is freely available to download now at: http://www.oracle.com/technetwork/server-storage/linux/downloads/oracle-linux-7-2170224.html
3) Ubuntu 14.10 alpha
The first alpha of Ubuntu 14.10, the Utopic Unicorn was released on June 27. This is still very early on in the process, but 14.10 is widely expected to further Mark Shuttleworth's vision of a fully converged mobile, server and desktop operating system.
