Pandemics and wars have woken up countries and companies to the strategic vulnerabilities in their infrastructure dependencies, with digital sovereignty now being a top concern, especially in Europe.

In this short talk, Thierry Carrez, the General Manager for the Open Infrastructure Foundation, will explore the critical role that open source has to play in general in enabling digital sovereignty. In particular, he will explore how Open Infrastructure (open source solutions for providing infrastructure), with its interoperability, transparency and independence properties, is essential to to reach data and computing sovereignty.

Over the past 12 years, OpenStack has become the de-facto standard for providing cloud infrastructure using open source solutions. But in the past 6 years, the ecosystem focus has shifted higher in the stack onto cloud-native solutions, which run on top of an existing cloud infrastructure. Does that mean that open source cloud infrastructure solutions, like OpenStack, are no longer relevant?

In this talk, Thierry Carrez, the General Manager for the Open Infrastructure Foundation, the non-profit hosting the OpenStack project, will explore this question. After examining the motivation and history of OpenStack over the past decade, we will explore what makes OpenStack relevant in the next decade, with a special attention to the European context. While it is not for everyone, new use cases like Digital Sovereignty or Edge computing are driving renewed adoption of OpenStack, especially in combination with Kubernetes (what is called the Linux OpenStack Kubernetes Infrastructure, or LOKI).

A lot of open source developers choose to deploy their software on infrastructure based on proprietary software. Behind this apparent paradox is the need to adapt to changing environments, adopt new technologies fast, and use increasing amounts of computing power. Open infrastructure (computing, networking and storage infrastructure based on open source software) has a lot to offer, but it's easy to overlook if you don't take the time to take a step back and analyze the situation rationally. In this talk, Thierry Carrez, VP of Engineering at the OSF, explains all the reasons why open infrastructure matters, and why it makes sense for you to adopt it today.

Outline of this talk:

• Infrastructure (what do we mean by infrastructure, and why it matters in the general evolution of computing)
• Open (key benefits of using open source software in general, and openly-developed community-led projects in particular)
• Capabilities, Compliance and Cost (extra benefits of using open source software for providing infrastructure)
• Interoperability (benefits of using the same open source projects across providers)
• Future-proof (open source allows to invest in adaptive communities rather than static products)
• Enabling innovation everywhere (infrastructure should not be only provided by a couple of Internet giants like Amazon and Google)

Today, the task of running containers involves a lot of technologies and levels of abstraction, and it can be difficult to understand, or just to keep up. How do CRI-O and containerd overlap ? Does Kata containers compete with Firecracker ? Is there any relationship between OCI and CRI ? How many different meanings can "container runtime" have ?

In this talk, we will navigate this treacherous sea of overlapping technologies and acronyms that take care of running container workloads, below Kubernetes all the way down to the Linux kernel. We will present at a high-level how these technologies, interfaces and levels of abstraction combine and overlap, and hopefully clarify which are spec vs. implementation, which are complementary, and which are alternative solutions.

This talk will cover the following points:

• The world used to be simple: the case of Docker
• Interfaces: OCI and CRI
• More puzzle pieces: Podman, Containerd and CRI-O
• Workload isolation: Kata Containers, GVisor and Firecracker
• Q&A

A presentation of original open source tools created for (and used by) the OpenStack project infrastructure.

Last year at FOSDEM I gave an overview of the OpenStack project infrastructure, a Puppet-driven collection of free software tools which ensure continuous integration at the crazy pace of the OpenStack projects.

While a number of these tools are well-known (Puppet, Jenkins, Gerrit), we also created our own free software tooling to support our unique needs, and those are potentially useful for any software project development infrastructure.

Come one, come all. Step right up and prepare to be amazed! Learn more about Zuul, our fearless pipeline-oriented gatekeeper. Be surprised by jenkins-job-builder, our YAML-driven err... Jenkins job builder. Make Gerrit saner with git-review, JeepyB or gertty. And don't leave without discovering StoryBoard, our amazing future task tracker.

OpenStack is a large infrastructure software stack openly developed by hundreds of developers across the world, producing hundreds of changes per day. How do we stay sane, make sure this complex software stack works, and produce releases every 6 months like clockwork?

In this talk, we'll look into the principles behind the OpenStack gate, which ensures that every proposed change goes through rigorous automated testing before being merged. We'll look into the implementation details of our cloud-based solution, which involves Jenkins, Gerrit and a set of homegrown open source tools. We'll explore the unique set of challenges created by running such a strict gating system while maintaining our development velocity. And best of all, we'll see how this whole system setup is entirely automated by Puppet with open-sourced configuration everyone can contribute to.

This talk should appeal to anyone interested in successfully applying testing and automation principles in large open source projects. No previous knowledge of OpenStack is necessary.

This talk should appeal to curious developers interested in learning about OpenStack development and why contributing to it is a smart, interesting, and simple move. Although familiarity with open source development is assumed, no previous knowledge of OpenStack itself is necessary.

OpenStack is a software stack written in Python that you can use to deploy public and private "Infrastructure as a service" providers, potentially at massive scale. This talk will look into why contributing to OpenStack should be interesting to you personally, where in the various pieces and teams of OpenStack you should consider helping, what various shapes your contribution to OpenStack may take, and finally deep dive in the details of our development infrastructure and how you can actually make your first contribution.

The 30-month-old OpenStack project arguably created the hottest job market for open source Python developers. Plenty of us make a very decent living working all day long writing Python for an open source project, why not you ?

In this presentation, we will introduce what OpenStack is about, what Python libraries we use, how our meritocratic governance places the individual technical contributors in control, how to contribute and become a visible (and desirable) member of our community, and where to look for Python OpenStack jobs.

What changed in the OpenStack world over the last year ? Growth, governance transition to the OpenStack Foundation and Technical Committee, addition of new projects, adoption everywhere...

We'll look back at what happened since last year presentation at FOSDEM, then present the key new features that should be delivered in the upcoming Grizzly release in April.

The OpenStack developers ecosystem consists of OpenStack core developers, but also upstream project developers and downstream distribution packagers, producers of compatible tools... In this town hall meeting, we will all gather for an informal workshop where we'll openly discuss issues and how we can solve them as a community. In particular, we'll have a panel discussion with packagers from various distributions, but we also expect themes like project policies, QA or governance to be addressed. Come and join us !

OpenStack is a common effort to produce open source software to implement scalable Infrastructure as a Service providers. What happened in the project since FOSDEM 2011 presentation ? This talk will quickly introduce what OpenStack is about and the changes over the last year: Growth, new core projects, continuous integration changes and what's coming up in the Essex release.
