Clusters is a Buildkite feature used to manage and organize agents and queues, which:

• allows teams to self-manage their Buildkite agent pools,
• allows admins to create isolated sets of agents and pipelines within within a single Buildkite organization,
• helps make agents and queues more discoverable across your organization,
• gives you more control over your agents and queues like pausing them, and
• provides easily accessible queue metrics.

All existing agents can now be accessed through Unclustered grouping on the agents page.
