The idea was born from an online mailing list that began on November 27, 1997. In the end, Harald Milz wrote an odd type of Linux-HA-related HOWTO. In contrast to most HOWTOs, it focused on setting up or utilizing existing software. It was a compilation of HA methods that could be used in writing HA programs for Linux.
Alan Robertson was inspired by the description above and thought of the possibility of writing some of the programs for the project as a kind of initial seed crystal that could help kick-start the project. He launched the first website in the name of the initiative on October 19, 1998. The first version of the software was put in operation on March 18, 1998. The first release of software went live on November 15, 1998. The first customer to use this software was Rudy Pawul of ISO-NE. The ISO-NE website went to production during the last quarter of 1999.
At this stage, the project was limited to two nodes with simple takeover semantics, and there was no monitoring of resources.
This was remedied with the release of version 2.0.0 of the software that added the n-node cluster, resource monitoring, dependencies, and policies. Version 2.0.0 was released on July 29, 2005. The release was an additional significant milestone since it is the initial release that had significant contributions (in terms of the size of the code) were contributed by the community of Linux-HA in general. This series of releases brought the project to a level of feature parity or superiority concerning commercial HA software.
After the release of version 2.1.4, the Cluster Resource Manager component (responsible for beginning and stopping resources and monitoring node and resource failure) was separated into a separate project dubbed Pacemaker.  The resource agents, as well as additional "glue" infrastructure, were moved into separate applications. Therefore, in the version 3 series, the name Heartbeat is used only for that layer for cluster-based messaging.
