400;\">The main goal of distributed Kubernetes is to orchestrate workloads to containers. However, Rancher was created by SUSE to provide capabilities beyond those of regular Kubernetes distributions. Rancher is an enterprise-grade platform that supports consistent administration of multiple Kubernetes clusters from a single user interface\u2014while addressing key Kubernetes pain points, such as cluster deployment, workload distribution workflow, security management, cross-cluster workload monitoring, and scalability.\u00a0<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">In short, Rancher simplifies managing, monitoring, importing, and provisioning Kubernetes clusters with just a few clicks from its intuitive user interface. But how does Rancher achieve this? The following diagram gives you a more intuitive view of this:<\/span><\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-14602 size-full\" src=\"https:\/\/gcloudvn.com\/wp-content\/uploads\/2023\/07\/rancher_kubernetes_2.jpg\" alt=\"How Rancher helps manage Kubernetes better 2\" width=\"600\" height=\"338\" srcset=\"https:\/\/gcloudvn.com\/wp-content\/uploads\/2023\/07\/rancher_kubernetes_2.jpg 600w, https:\/\/gcloudvn.com\/wp-content\/uploads\/2023\/07\/rancher_kubernetes_2-18x10.jpg 18w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Cac_thanh_phan_chinh_cua_Rancher\"><\/span><b>Rancher&#039;s main components<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Rancher server: You can think of the Rancher server as the heart of the Rancher cluster, as it includes major components, such as etcd, authentication proxy, Rancher server API, and cluster controller.
