Redundancy & Fault Tolerance
Solace PubSub+ appliances and Solace PubSub+ software message brokers can operate in high-availability (HA) redundant pairs for fault tolerance. HA redundancy provides 1:1 message broker sparing to increase overall service availability. If one of the message 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 message broker. In this section we'll show you how to configure the HA feature on Solace PubSub+ message brokers.
