Starting from PVE 6.0, Corosync 3.x is in use (not compatible with earlier PVE versions). Individual virtual servers can be configured for high availability using the integrated HA manager. [28] [29] If a Proxmox node becomes unavailable or fails, the virtual machines can be automatically moved to another node and restarted. [30]
LXC is similar to other OS-level virtualization technologies on Linux such as OpenVZ and Linux-VServer, as well as those on other operating systems such as FreeBSD jails, AIX Workload Partitions and Solaris Containers. In contrast to OpenVZ, LXC works in the vanilla Linux kernel requiring no additional patches to be applied to the kernel sources.

OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
IPFire is a hardened [3] open source Linux distribution that primarily performs as a router and a firewall; a standalone firewall system with a web-based management console for configuration.

Pdnsd is a caching DNS proxy server that stores cached DNS records on disk for long term retention. Pdnsd is designed to be highly adaptable to situations where net connectivity is slow, unreliable, unavailable, or highly dynamic, with limited capability of acting as an authoritative nameserver. It is licensed under the GPL. [17]
A content delivery network or content distribution network (CDN) is a geographically distributed network of proxy servers and their data centers. The goal is to provide high availability and performance ("speed") by distributing the service spatially relative to end users.
