Virtual private servers are commonly used in web hosting services, where they are useful for segregating customer accounts, pooling resources and containing any potential security breaches. To save space on such installations, each virtual server's file system can be created as a tree of copy-on-write hard links to a "template" file system. The ...

OpenVZ is similar to Solaris Containers and LXC.
Starting from the PVE v.6.0 Corosync v.3.x is in use (not compatible with the earlier PVE versions). Individual virtual servers can be configured for high availability, using the built-in ha-manager. [28] [29] If a Proxmox node becomes unavailable or fails, the virtual servers can be automatically moved to another node and restarted. [30]

[16] [17] Each virtual machine, called an "instance", functions as a virtual private server. Amazon sizes instances based on "Elastic Compute Units". The performance of otherwise identical virtual machines may vary. [18] On November 28, 2017, AWS announced a bare-metal instance, a departure from exclusively offering virtualized instance types. [19]
