About DevConf

DevConf.CZ 2021 is the 13th annual, free, Red Hat sponsored virtual community conference for developers, admins, DevOps engineers, testers, documentation writers and other contributors to open source technologies. The conference includes topics on Linux, Middleware, Virtualization, Storage, Cloud and mobile. At DevConf.CZ, FLOSS communities sync, share, and hack on upstream projects together.

While we are disappointed that we won’t be able to see you all in person, we're shifting to an awesome virtual event in 2021!

There is no admission or ticket charge for DevConf.CZ events. However, you are required to complete a free registration. Watch this site for updates about registration.

We are committed to fostering an open and welcoming environment at our conference. We set expectations for inclusive behavior through our code of conduct and media policies, and are prepared to enforce these.

Session formats

We are switching to a virtual format in 2021 and we want to make sure all CfP submission types are clearly defined and adjusted to the virtual environment. Have a look at the detailed descriptions and as always, we’re open to new ideas!


A talk is where you talk using slides and demos to an audience that listens. A talk is either 20 or 40 minutes long, make sure you reserve time at the end for Q&A. If speakers wish to continue with the Q&A after their time slot, there will be a dedicated place for it. Feel free to recruit your colleagues to interact with people in chat while you are talking. A talk has one primary speaker, optionally another (secondary) speaker.

A talk should be bite-sized and focused on a certain topic. This means that you should not expect to be able to cover multiple broad areas in one talk. You can submit more than one proposal, to cover a set of topics, but we cannot guarantee their final scheduled order. Therefore, we recommend topics be structured in a way so as to minimize their interdependence so that they do not need to be presented in a specific order.

We give speakers a choice to speak live or send us a pre-recorded session. We understand pre-recording your session requires extra time and extra set of skills and we are currently considering ways to make it easier for you. If you choose to pre-record your session, remember it only needs to be as good as you would do live. This is not a Hollywood movie :)


A discussion is a bit where you lead/moderate a discussion with a group of knowledgeable panelists where they answer prepared questions or questions from the audience as selected by you for appropriateness to your topic and session’s goal. It is more interactive than a talk because you could engage with the audience during the session. If you are willing to open the discussion to attendees, consider holding a fishbowl discussion where you start with a group of speakers and an empty “seat” which could be filled by active audience members in the course of a discussion.

A discussion is 40 minutes long. If speakers wish to continue after the 40-minute slot, there will be a dedicated place for it. A discussion has a dedicated moderator and up to 5 active speakers.

Discussions are delivered live. We do not accept pre-recorded discussions.


A workshop is a hands-on demo where you and other workshop leads interact among each other and with audience members on chat, sharing your knowledge and experience on a particular bite-sized topic. The goal of a workshop is to teach or practice a skill. You should not expect the audience following each step of the worksop live, however, they should have all necessary instructions if they wish to. As a result workshops should be actionable and goal oriented.

A workshop is 40 minutes long, although we will consider exceptions. The number of attendees is not limited like it would be in an in-person event.

We allow up to 3 active presenters in a workshop. You must designate one of them to be the primary session leader. Feel free to recruit your colleagues to interact with people in chat while you are talking.

All workshops are conducted live. We do not accept pre-recorded workshops. However, you may find it useful to pre-record demo components of your workshop.

Meetups, Booths and Contests

Meetups and booths are open to all participants, they serve as a place for open discussions, sharing the latest project developments and interaction with contributors and attendees.

We recognize that adjusting booths and meetups to the virtual environment is very challenging and we are considering steps we can take to ensure high meetup and booth traffick. We are working on a list of suggestions for virtual booths and meetups. We are open to working together with booth staff and meetup organizers in order to find the best possible solution in the virtual environment.

Contests are easy to set up, there should be an intro meeting for those who want to join and then they can work on their own. We will provide a chat channel to help and monitor the contest.

  • Agile, DevOps

    The Agile, DevOps track is intended to address the practices, methods and tooling that technical audiences need to deliver increased business value and responsiveness through rapid, high-quality delivery. Topics include engineering best practices, defining and building Agile & DevOps cultures, Open Source tools to make Developers and Operations successful, and many more.

    Cloud and Containers

    Cloud, containers, clusters. Buildah, CRI-O, Docker, Kubernetes, Skopeo. Hybrid cloud and other buzzwords - your cloud and container topics go here. Daemons of all sizes and shapes.

  • Community

    Building open source software is more than just about coding. Learn about the many aspects of creating and maintaining healthy, robust, and diverse open source communities.

    Debug / Tracing

    Developer tools for debugging and tracing your application and its enviroment. Kernel level to userland application level.

  • Desktop

    Traditional and new package management tools, GUI applications, optimizations for the desktop, anything desktop-related goes here.

    Developer Tools

    Developer tools for planning, creating, compiling, running, and analyzing code. Including all programming languages, frameworks and online development environments.

  • Documentation

    Guides, manuals, howtos, articles, and other kinds of help content. New ideas, documentation workflows, user-story focus, modularity, and automation.


    All things Fedora!

  • Frontend / UI / UX

    The Frontend/UX/UI track is intended to address user experience design, user interface design, and front end development. Topics include: processes and tools related to design and frontend development, approaches to research and collecting user feedback, and strategies towards increased transparency for design and development across teams.


    All things Linux Kernel

  • Immutable OS

    Everything from the previous CoreOS and Atomic operating systems to the new Fedora CoreOS, an automatically updating, minimal, monolithic, container-focused operating system, designed for clusters while also operable standalone. Server-related topics around rpm-ostree too.

    IoT (Internet of Things)

    Data crunching applications, microcontrollers, protocols and embedded software. Development and testing tools. Deployment and maintenance techniques. Security challenges and interesting use cases.

  • Microservices

    Microservices architecture, design, challenges, patterns and testing. Including RHOAR based technologies (Vert.x, Spring Boot, Node.js, Thorntail, MicroProfile, Fuse) and other platforms, including development & production related topics.


    Infrastructure exists to run applications, and applications are built on Middleware. Red Hat has several runtimes and services designed to integrate with our platforms for efficient performance and rapid development.

  • ML / AI / Big Data

    Development tools for data engineering and data science, model development and deployment, interesting models to solve problems, e.g., in software engineering, system/cloud administration.


    What is on the horizon for the next 3-12 months for networking. What is work in progress and will land in next few months. What are the directions we would want to take things in. How can networking solve some of the existing problems for our customers, our layered products. How can networking solve the bottlenecks in layered products.

  • Platform / OS

    Anything related to GNU/Linux base operating system - when it does not better fit to other tracks ;)

    Quality / Testing
