3. Rings proposal
Fedora.next & Fedora Rings

4. Starting the solution
Don't forget about cloud-atomic
Fedora Editions

5. Rings Don’t work
Different user scenarios have different risks

6. What we are doing and how
Aleph: Kind of rings (sets really) for numbers a-0 = integers, a-1 = ordinal numbers, etc
What we are doing and how

7. What is a module? A thing that is managed as a logical unit
A thing that promises an external, unchanging, API
A thing that may have many, unexposed, binary artifacts to support the external API
A module may “contain” other modules and is referred to as a “module stack”

8. Base Runtime (Module Stack)

9. modulemd: Describe a module

10. Progress
Established the Modularity WG, subsumed Envs & Stacks and Base WGs
Implemented a dnf plugin
Implemented an alpha version of the module build pipeline
Implemented an alpha of the pipeline visualization
Ability to “coalesce” modules for testing
Kicked off Base-Runtime
