Fedora 27 - Modular Server

Interesting development.
Fedora = the basis for Rhel and thus the upcoming new CentOS.

Building a modular Linux OS with multiple versions of components on different lifecycles.



Summary
The Fedora Project just released the beta version of Fedora 27, including Fedora Workstation and Fedora Atomic Host. Since Fedora ships with three editions, you may be wondering: where’s Fedora 27 Server beta?

The short answer: it’s coming soon. Remember Boltron, the Modular Server Preview from a few months ago? The Fedora Server team has been building on feedback from that preview and plans to make the next Fedora Server release based on this technology. But, the team also wants to make sure it would be actually useful to you, not just another preview. And, when it came time to make the general beta release, the team decided it wasn’t ready yet.

Waiting For Fedora Modular Server
The Modularity project was designed to allow shipping different parts of the projects on different timelines. So, the Server team is starting that now — expect a Fedora 27 Server beta powered by Modularity in a few weeks. The general Fedora 27 release will come in early November, and then Fedora 27 Server will arrive in final form about a month later.

Once all of the planned content is in place, Modularity will allow users to choose different streams of runtimes and applications, allowing base operating system updates without disruption to workloads.
