The Linux world supports various cluster software; for application clustering, there is distcc, and MPICH. Linux Virtual Server , Linux-HA – director-based clusters that allow incoming requests for services to be distributed across multiple cluster nodes.
The NonStop Clusters were commercialized by Santa Cruz Operation as an add-on for UnixWare. When SCO Group stopped selling the product, the developers (brought in by the Tandem acquisition and now working at Compaq) ported the ″NonStop Clusters″ code to Linux and in 2001, now called OpenSSI, released it as open source.

Clustered file systems can provide features like location-independent addressing and redundancy which improve reliability or reduce the complexity of the other parts of the cluster. Parallel file systems are a type of clustered file system that spread data across multiple storage nodes, usually for redundancy or performance.
The High Availability Add-On is Red Hat's implementation of Linux-HA. It attempts to ensure service availability by monitoring other nodes of the cluster. All nodes of the cluster must agree on their configuration and shared services state before the cluster is considered to have a quorum and services are able to be started.
High-availability clusters (also known as HA clusters, fail-over clusters) are groups of computers that support server applications that can be reliably utilized with a minimum amount of down-time. They operate by using high availability software to harness redundant computers in groups or clusters that provide continued service when system ...
High-availability cluster. Apache Mesos, from the Apache Software Foundation; Kubernetes, founded by Google Inc, from the Cloud Native Computing Foundation; Heartbeat, from Linux-HA
The Linux-HA (High-Availability Linux) project provides a high-availability solution for Linux, FreeBSD, OpenBSD, Solaris and Mac OS X which promotes reliability, availability, and serviceability (RAS). [1] The project's main software product is Heartbeat, a GPL-licensed portable cluster management program for high-availability clustering. Its ...
