CFP for CNCF-hosted Co-located Events


CNCF-hosted co-located events are masterfully designed to foster discussion, collaboration, and knowledge-sharing in a vendor neutral space with participants just like you!  Connect with fellow attendees interested in Argo, Cilium, Telco, Web Assembly, Kubernetes Batch + HPC, Kubernetes on Edge, Istio, Linkerd, OpenTelemetry, Prometheus and more. From technical sessions to lightning talks, CNCF-hosted co-located events support the future of cloud native computing.

Please review this page in it’s entirety and if you are unable to find an answer to your questions, please email cncfcolocatedevents@linuxfoundation.org.

If you have not yet used the CFP system, you will be required to register and create an account before submitting.
Please CREATE YOUR ACCOUNT before submitting for the first time. Thank you!

First Time Submitting? Don’t Feel Intimidated.

CNCF-hosted co-located events are an excellent way to get to know the community and share your ideas and the work that you are doing. You do not need to be a chief architect or long-time industry pundit to submit a proposal, in fact, we strongly encourage first-time speakers to submit talks for all of our events.

Our events are working conferences intended for professional networking and collaboration in the CNCF community, and we work closely with our attendees, sponsors and speakers to help keep CNCF events professional, welcoming, and friendly. If you have any questions on how to submit a proposal or the event in general, please contact cncfcolocatedevents@linuxfoundation.org.

If you aren’t ready to submit, view the submission form to help you prepare.

We also recommend first time speakers review this talk “Getting Over Your Imposter Syndrome to Become a Conference Speaker – Dawn Foster, VMware”.

Requirements + Considerations

  1. Any platforms or tools you are describing need to be open source.
  2. You may only be accepted to speak on one panel and one non-panel accepted session per CNCF-hosted co-located event.
  3. All panel submissions with 3–5 speakers are required to have at least one speaker that does not identify as a man, and the speakers must not all be from the same company. Cloud Native Computing Foundation does not accept submissions with all-male panels in an effort to increase speaker diversity. Additionally, panel submissions must include the names of all participants in the initial submission to be considered.
  4. We will not select a submission that has already been presented at a previous CNCF or Linux Foundation event within the last year. If your submission is very similar to a previous talk, please include information on how this version will be different.
Consider the Following as You Write Your Proposal
  1. What do you expect the audience to gain from your presentation?
  2. Why should YOU be the one to give this talk? You have a unique story. Tell it.
  3. Be prepared to explain how this fits into the Cloud Native and overall Open Source Ecosystem.

We definitely do not expect every presentation to have code snippets and technical deep-dives, but here are two things that you should avoid when preparing your proposal because they are almost always rejected due to the fact that they take away from the integrity of our events, and are rarely well-received by conference attendees:

  1. Sales or marketing pitches
  2. Unlicensed or potentially closed-source technologies

There are plenty of ways to give a presentation about projects and technologies without focusing on company-specific efforts. Remember the things to consider that we mentioned above when writing your proposal and think of ways to make it interesting for attendees while still letting you share your experiences, educate the community about an issue, or generate interest in a project.

How to Submit Your Proposal

We have done our best to make the submission process as simple as possible. Here is what you will need to prepare:

1. Choose a submission format:

  • Presentation: 25 minutes, 1 or 2 speaker(s) presenting a topic
  • Panel Discussion: 35 minutes of discussion amongst 3 to 5 speakers
  • Lightning Talk: A brief 5-minute presentation, maximum of 1 speaker

Note: Note: All submissions with 3–5 speakers are required to have at least one speaker that does not identify as a man and the speakers must not all be from the same company.

2. Select the level of expertise intended for the audience.

  • Any: Anyone can attend, no domain, content familiarity, or specialty specialty experience necessary
  • Beginner: Very basic information requires junior domain, content familiarity, or specialty experience at a minimum
  • Intermediate: Mid-level experience
  • Advanced: Expert-level experience

3. Choose a CNCF-hosted co-located event.

4. Choose your topic. Topics per CNCF-hosted co-located event are listed within the CFP application.

5. Provide a detailed and focused description with a max of 1,000 characters. This is what will be used on the online schedule if your talk is accepted.

6. Provide more in-depth information in the “Benefits to the Ecosystem” section. This is your opportunity to elaborate on your content and share more details with the program committee with a max of 1,000 characters.

7. Provide a biography for all speakers, including previous speaking experience.

6. Provide resources to enhance your proposal. These can be videos of you or your speakers presenting elsewhere, links to personal websites (including LinkedIn), links to your open source projects, or published books.

Sample Submission

Your session description will be the cornerstone of your proposal.

This is your chance to *sell* your talk to the program committee, so do your best to highlight the problem/contribution/work that you are addressing in your presentation. The technical details are still important, but the relevance of what you are presenting will help the program committee during the selection process.

This is the description that will be posted on the website schedule, so please ensure that it is in complete sentences (and not just bullet points), free of typos and that it is written in the third person (use your name instead of “I”).


OCI, CRI, ??: Making Sense of the Container Runtime Landscape in Kubernetes – You’ve probably heard about the OCI—a standardization effort to share a common definition for container runtime, image, and image distribution. Add to that the CRI (container runtime interface) in Kubernetes—designed to abstract the container runtime from the kubelet—and you may start to wonder what all these standards and interfaces mean for you in a Kubernetes world.

As of this year, a long list of runtimes, including CNCF projects containerd and cri-o, all implement the CRI. But did you know there are quite a few others? The unique number of CRI combinations is growing, all of which use the common OCI definitions for runtime and image interoperability.

But how would you decide which container runtime is right for you? Clearly each one has tradeoffs. This talk will help describe the current landscape and give you details on the why and how of each CRI implementation available today.

Benefits to the Ecosystem

This is your chance to elaborate. Tell us how the content of your presentation will help better the ecosystem, or anything you wish to share with the co-chairs and program committee. We realize that this can be a difficult question to answer, but as with the description, the relevance of your presentation is just as important as the content. Max of 1,000 characters.


It is a repeating comment across the CNCF ecosystem that the number of choices for container runtime is confusing, especially for those who are newer to our ecosystem. Even for those who many have heard the names–Docker, containerd, cri-o–even they are curious as to the reasons why there are many varied runtimes available to implement the CRI interface for Kubernetes, and what is the history that brought us to this point.

This talk helps bring clarity to the container runtime landscape, and especially shows the interesting work being done in additional isolation technologies like gVisor, AWS Firecracker, and Kata containers and why that may be of value to consider for certain security or workload constraints.

In the end, especially as we have two major runtimes as CNCF projects, this talk hopefully brings a level of insight to practitioners, developers, and operators as to why clusters may choose various runtimes and how new features in Kubernetes like RuntimeClass are making it easier to support mixed clusters that can support the needs of workloads with different isolation features or requirements.

Scoring Guidelines

To help you further understand what is considered while the program committee and co-chairs are reviewing your proposal, please review the Scoring Guidelines and Best Practices page.
