Fleet is designed to manage up to a million clusters. It’s also lightweight enough that it works great for a <a href="https://fleet.rancher.io/installation#default-install" target="_blank" rel="noopener noreferrer">single cluster</a> too, but it really shines when you get to a <a href="https://fleet.rancher.io/installation#configuration-for-multi-cluster" target="_blank" rel="noopener noreferrer">large scale</a>. By large scale we mean either a lot of clusters, a lot of deployments, or a lot of teams in a single organization.</p><p>Fleet is a separate project from Rancher, and can be installed on any Kubernetes cluster with Helm.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="architecture">Architecture<a href="#architecture" class="hash-link" aria-label="Direct link to Architecture" title="Direct link to Architecture"></a></h2><p>For information about how Fleet works, see the <a href="/integrations-in-rancher/fleet/architecture">Architecture</a> page.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="accessing-fleet-in-the-rancher-ui">Accessing Fleet in the Rancher UI<a href="#accessing-fleet-in-the-rancher-ui" class="hash-link" aria-label="Direct link to Accessing Fleet in the Rancher UI" title="Direct link to Accessing Fleet in the Rancher UI"></a></h2><p>Fleet comes preinstalled in Rancher and is managed by the <strong>Continuous Delivery</strong> option in the Rancher UI.
