Clustering Applications in a RHEV V3 Environment using the RHEL High Availability Add-On


This reference architecture demonstrates the use of the Red Hat Enterprise Linux High Availability Add-On running on virtual machines within a Red Hat Enterprise Virtualization environment. This paper creates two separate high availability clusters within environment. The first cluster creates an active-passive PostgreSQL database service. The second cluster creates a virtual instance of a central logging server that stores log events in a PostgreSQL database instance.
