Modularity brings multiple versions of applications and language stacks to Fedora — so you can choose the right version you need for your application. Multiple versions allow for life cycles that go beyond a single release of a distribution. This could allow you to stay on older versions across major versions of the underlying operating system. Fedora 28 Server is the first deployment ready Fedora release including Modularity. Come and learn what it means and see how you can benefit from a server OS that gives you the ability to move both fast and slow at the same time. Containers included, but not required.

4 . Benefits of Linux distributions

5 . Packaging makes software integrated, tested, updated, and easily installable.

6 . Lifecycle brings an over-time stability to the diverse open source world.

11 . Lifecycle differences are very useful, because different people have different needs

12 . Lifecycle quotes Quote 1: “Fedora is too fast for me.” Quote 2: “Fedora is too slow for me.”

13 . Can Fedora be fast and slow at the same time? “Fedora is too fast for me.” “Fedora is too slow for me.”

14 .Fedora Modularity

15 . Packages are the core building blocks of Linux distributions.

16 . Modules are logical groups of packages representing an application, or a language runtime.

17 .Module benefits: • multiple streams • lifecycle independence • use case-driven installation

18 . Modules in Fedora 1) Traditional releases before Modularity Fedora 26 Fedora 27 nodejs-6.rpm nodejs-8.rpm

19 . Modules in Fedora 2) Fedora 28 introduced Modularity Fedora 28 nodejs-6.rpm nodejs-6.rpm nodejs-8.rpm nodejs-8.rpm nodejs-10.rpm nodejs-10.rpm Fedora 26 Fedora 27 nodejs-6.rpm nodejs-8.rpm nodejs-8.rpm

20 . Modules in Fedora 3) Modules have multiple streams Fedora 28 nodejs-6.rpm nodejs-6.rpm nodejs-8.rpm nodejs-8.rpm nodejs-10.rpm nodejs-10.rpm nodejs-8.rpm

21 . Modules in Fedora 4) Modules have independent lifecycles Fedora 28 Fedora 29 nodejs-6.rpm nodejs-6.rpm nodejs-8.rpm nodejs-8.rpm nodejs-10.rpm nodejs-10.rpm nodejs-8.rpm nodejs-10.rpm

22 . Thanks to modules, your system can move fast and slow at the same time.

23 . Thanks to modules, your system can move fast and slow at the same time. Packaging + lifecycle benefits included.

24 . Defaults mean that you can choose a specific version only when you want to.

25 . Updates will respect your choice and won’t upgrade to a different stream.

27 . Modularity and Containers

28 . Containers make applications more portable by containing their dependencies.

29 . Containers are so simple, it is sometimes tempting to just find one and run it.
