CentOS Stream is where RHEL development happens in public. You can preview content coming to RHEL, test your things on top of it, and even participate! We'll show you how it works, highlight the key differences between Fedora ELN, CentOS Stream and RHEL, and see where it's all happening.

While showing some level of technical detail, this talk will be high-level, intended for anyone curious about Linux distributions. You'll learn about possible use cases of CentOS Stream, about how code flows into RHEL starting with Fedora, and how you can potentially influence goes into RHEL.

Deploying software has lots of solutions, but what gets deployed often plays out as a fight between developers and operators. Developers want the latest (or at least later) code. Operators want things in nice packages, certified, and with a known period of support. What we need is a catalog of software with the variety of versions the developers need, with the qualities expected by the operators. Come and learn how various projects within Fedora approach this problem from different perspectives, including Fedora Modularity, containers, Fedora CoreOS, and Fedora Silverblue.

This session contains a high-level overview as well as a live (or recorded) demo of Fedora Modularity — a project bringing multiple versions of packages in Fedora with the qualities expected from a Linux distribution: transparently built and delivered, actively maintained, and easy to install. In other words, having the flexibility that developers need and the qualities operators need.

Followed by a demonstration of why building containers using Linux distributions' packages makes your life easier. And now with Modularity there's more versions of software to choose from.

Ending with a quick intro into container distributions for the server (Fedora CoreOS) and for the workstation (Fedora Silverblue) — demonstrating the benefits of having an immutable small OS which is possible thanks to applications in containers.

Expected audience: system administrators and developers

Come and learn how developers and operators can be friends by using packaged software from Linux distributions, and what Fedora has to offer to both!

Following the progress of the Modularity initiative and Factory 2.0 developments in Fedora, it's about time we define what the next, modular operating system should look like, focusing on the developer’s point of view.

This first half of this talk will present the main concepts of Modularity, explaining in detail what modules are, how they get built, composed, distributed and kept updated once deployed on the target system.

The second half of the talk will explore the idea of the so-called Generational Core, often also referred to as Base Runtime — a modular platform base on top of which application modules can both be built and executed.

Both these topics cover ongoing efforts and we don’t yet have definitive answers to all the questions. We’ll talk about what we learned in the past year, what problems we’re trying to solve and our plans for the future.
