Proxmox VE can be used independently without being part of a cluster. But in order to truly use Proxmox at its full potential, a cluster enables many more advanced features such as centralized management, high availability, and live migration. We will look into the features in later chapters. When multiple Proxmox nodes are in the same cluster, they can all be managed and monitored by logging in to the Proxmox GUI through any member node. There is no master-slave scheme in Proxmox. All nodes works together by sharing the same configuration.
