Proxmox boxes can be clustered together to build a High Available (HA) cluster. Clustering allows work load balance across hosts and centralized management of virtual machines. Ability to perform real-time live migration of virtual machines across nodes, even during hardware failures assures continuous service availability . This makes the cluster a High Availability virtualization cluster. Live migrations across nodes allows the system administrator for capacity scaling with almost no downtime.
Our Proxmox virtualization support team helps you in setting up a high available virtualization system for bare metal virtualization and Operating system level virtualization.
