High Availability (HA) Overview
Solace PubSub+ appliances and Solace PubSub+ software event brokers can operate in high-availability (HA) redundant groups for fault tolerance. HA redundancy provides 1:1 event broker sparing to increase overall service availability. If one of the event brokers fails, or is taken out of service, the other one automatically takes over and provides service to the clients that were previously served by the now-out-of-service event broker. In this section we'll show you how to configure the HA feature on Solace PubSub+ event brokers.
