Who is using Cilium?
====================

Sharing experiences and learning from other users is essential. We are
frequently asked who is using a particular feature of Cilium so people can get in
contact with other users to share experiences and best practices. People
also often want to know if product/platform X has integrated Cilium.
While the [Cilium Slack community](https://cilium.herokuapp.com/) allows
users to get in touch, it can be challenging to find this information quickly.

The following is a directory of adopters to help identify users of individual
features. The users themselves directly maintain the list.

Adding yourself as a user
-------------------------

If you are using Cilium or it is integrated into your product, service, or
platform, please consider adding yourself as a user with a quick
description of your use case by opening a pull request to this file and adding
a section describing your usage of Cilium. If you are open to others contacting
you about your use of Cilium on Slack, add your Slack nickname as well.

    N: Name of user (company)
    D: Description
    U: Usage of features
    L: Link with further information (optional)
    Q: Contacts available for questions (optional)

Example entry:

    * N: Cilium Example User Inc.
      D: Cilium Example User Inc. is using Cilium for scientific purposes
      U: ENI networking, DNS policies, ClusterMesh
      Q: @slacknick1, @slacknick2

Requirements to be listed
-------------------------

 * You must represent the user listed. Do *NOT* add entries on behalf of
   other users.
 * There is no minimum deployment size but we request to list permanent
   production deployments only, i.e., no demo or trial deployments. Commercial
   use is not required. A well-done home lab setup can be equally
   interesting as a large-scale commercial deployment.
