+- The agent server for Kubernetes [is enabled by default](https://about.gitlab.com/releases/2022/02/22/gitlab-14-8-released/#the-agent-server-for-kubernetes-is-enabled-by-default)
+  on Omnibus installations. If you run GitLab at scale,
+  such as [the reference architectures](../administration/reference_architectures/index.md),
+  you must disable the agent on the following server types, **if the agent is not required**.
+
+  - Praefect
+  - Gitaly
+  - Sidekiq
+  - Redis (if configured using `redis['enable'] = true` and not via `roles`)
+  - Container registry
+  - Any other server types based on `roles(['application_role'])`, such as the GitLab Rails nodes
+
+  [The reference architectures](../administration/reference_architectures/index.md) have been updated
+  with this configuration change and a specific role for standalone Redis servers.
+
+  Steps to disable the agent:
+
+  1. Add `gitlab_kas['enable'] = false` to `gitlab.rb`.
+  1. If the server is already upgraded to 14.8, run `gitlab-ctl reconfigure`.
