| - title: "Offered CentOS Infra services for SIGs" |
| youtube: P5mW1Hc3w9Y |
| speakers: |
| - name: Fabian Arrotin |
| desc: | |
| In this talk, we'll do a quick recap about which kind of services (from git |
| hosting to building and cdn delivery, as well as CI testing) the CentOS Infra |
| team is offering and maintaining for the Special Interest Groups |
| - title: "MirrorManager and CentOS Stream 9" |
| youtube: ZCnhKL1UycM |
| speakers: |
| - name: Adrian Reber |
| desc: | |
| <p>Fedora relies on MirrorManager since 2008 and with CentOS Stream 9 CentOS |
| mirrors are now also managed by the MirrorManager instance.</p> |
| <p>For the CentOS community I want to use this session to give an overview how |
| MirrorManager works. I want to give an introduction about all the different |
| parts that are necessary to make MirrorManager work as well as how the Fedora |
| instance is set up. I also want to highlight how MirrorManager differs from |
| the traditional CentOS mirror infrastructure.</p> |
| <p>In addition to the introduction for the CentOS community I also want to present |
| what has changed in the last 6 years and how and why we rewrote core components |
| in Rust.</p> |
| - title: "One year on: Experiences using ebranch to bring over Fedora packages to EPEL" |
| youtube: 0oxHgY2SgVk |
| slides: "https://gitlab.com/CentOS/promo/centos-events/-/raw/main/2023-02-connect/ebranch.pdf" |
| speakers: |
| - name: Michel Salim |
| desc: | |
| <p>At this event last year, I described a WIP tool called ebranch |
| (https://pagure.io/epel/ebranch) that is meant to simplify the workflow |
| of branching a specific package for an EPEL release, together with all the |
| missing dependencies needed to build it.</p> |
| <p>One year on, this tool has been used for bringing over various sets of new |
| packages to EPEL, in different programming language stacks (from Python to |
| Perl to Rust); this talk discusses the current state of the tool, how features |
| are added to address specific needs, the experiences gained in writing and |
| using the tool, and the pros and cons of how different language stacks are |
| managed in Fedora when it comes to branching to EPEL.</p> |

| - title: "Introducing CentOS Stream CoreOS and OKD Streams" |
| speakers: |
| - name: Christian Glombek |
| - name: Alessandro Di Stefano |
| desc: | |
| <p>CentOS Stream CoreOS (SCOS) is a Linux distribution built from CentOS |
| Stream RPM packages, and focused on running container-based workloads |
| with Kubernetes. It is part of the SCOS Stream of OKD, the Kubernetes |
| community distribution of OpenShift, co-maintained by the CentOS Cloud |
| SIG and the OKD Working Group.</p> |
| <p>In this presentation, we'll present the technologies and methodologies |
| driving the CentOS Stream CoreOS (SCOS) release engineering, and the |
| Cloud-Native architecture we leverage to package the operating system |
| that runs Kubernetes/OKD.</p> |
| <p>We'll show how this framework, powered by Tekton pipelines and operated |
| via GitOps, can enable, thanks to rpm-ostree, the CoreOS Assembler and the |
| Layering model, delivery scenarios for different OSes beyond the Cloud-Native |
| ones: IoT, multimedia, automotive, thin-client-based environments. Users can |
| derive their own purpose-driven variants by maintaining a common multi-arch |
| base OS, distributed as a bootable Open Container Image (OCI).</p> |

| Rocky Linux to simplify the process of maintaining a downstream fork of |
| Red Hat Enterprise Linux. Discover how Peridot can be used to patch and |
| rebuild RPMs, modify upstream RPMs, or package your own software, and how |
| Rocky Linux uses it to manage the rebuilding of all packages in Enterprise |
| Linux and help drive upstream contributions while enabling Rocky's unique |
| special interests. This presentation is ideal for users of RHEL-like |
| operating systems who want to improve their Linux deployment and management |
| processes. Join us to learn about the benefits of Peridot and Rocky Linux |
| and how you can use them to optimize your Linux system and streamline your |

| - title: "From code to cloud - the journey of Openstack package" |
| youtube: jaoIph_mEqM |
| speakers: |
| - name: Karolina Kula |
| desc: | |
| OpenStack is a huge cloud computing project, which does not provide |
| packaging for platforms – RDO does it for rpm-based Linux distros. |
| Delivering packages for such project with new release every half a |
| year is a challenging task. In this talk I’d like to bring closer to |
| audience our continous-delivery approach to package delivery – starting |
| from creating and adding new packages, through updates and managing all |
| packages already delivered, share our practice in automation and tips |
| how to not get drown in dependencies of dependencies. The journey will |
| also have quick stop in building tools we are using in RDO and continuous |
| integration to ensure stability and compatibility, to finally reach the |
| point of having new OpenStack release. This talk is intended not only for |
| those, whose daily duties are connected with cloud or continous-delivery |
| technologies, but also for anyone interested in topic of delivering |
| packages at great scale in open source cloud project, or would like to |
| contribute to RDO. |
| - title: "A year in review 2023 - CentOS Automotive SIG" |
| youtube: YXEx83_y9VU |
| speakers: |
| - name: Eric Curtin |
| desc: | |
| A review of what's going on in our CentOS Automotive SIG, our AutoSD |
| image, how to run an AutoSD VM to try AutoSD, PREEMPT_RT kernel. Similar |
| in ilk to "Fedora: The Vehicle for Automotive Linux" presented by Stephen |
| Smoogen and Allison King at "Nest with Fedora 2022". |

| Running Cloud Native Applications on CentOS on a Cloud Native Processor; |
| Setting up and running a Mastodon Server on Arm servers in the cloud |
| youtube: rTepNBWgySo |
| speakers: |
| - name: Aaron Williams |
| desc: | |
| <p>In recent months, Mastodon has garnered a lot of attention, and seen a huge |
| influx of new users. Mastodon is a social network built on ActivityPub, a |
| protocol for federated social media. In early December, the network broke 8 |
| million users, and had 2.5M active daily users in one week.</p> |
| <p>That influx of new users and interest has led to many new Mastodon instances |
| being added, some with a very broad appeal, and others targeting smaller |
| groups and niche interests. It has also led to some of the more popular |
| instances of Mastodon struggling to scale with the new demand.</p> |
| <p>In this talk, we will walk you through how Mastodon’s federated architecture |
| is designed for the cloud and how easy Mastodon is to set up and run on a |
| CentOS instance on AArch64 cloud instances for free. And since Mastodon’s |
| backend is written in Ruby on Rails, using Redis and PostgreSQL, we will |
| show how easily they run on an AArch64 processor.</p> |
| <p>In addition, we will look at how well the Ampere Altra processor handles |
| cloud native workloads on CentOS. We will show you not only how to run |
| Mastodon on AArch64, but how to do it for free, without having to worry |
| about getting a large cloud bill. Recent events at Twitter gave us the |
| fun idea of how to combine all of this: create and run a Mastodon server |
| on Oracle Cloud’s (OCI) Always Free tier using Ampere A1 and CentOS.</p> |
| <p>We will also talk about some of the scaling issues that Mastodon runs |
| into, and how Ampere cores designed for cloud native workloads like |
| Mastodon are uniquely able to give you predictable throughput and |
| scaling as your server grows in popularity. All while doing this on a |
| processor that is more efficient (i.e. greener) than other processors |
| out there.</p> |
