Server Clustering
Server Clustering, available in PlanetPress Connect, enhances the processing capabilities of
PlanetPress Connect Server by load-balancing jobs between the main Server module (master)

module during the Installation Wizard, while the Slave Server is setup by installing the
PlanetPress Connect Server Extension module instead.
