Event Broker Redundancy
Solace PubSub+ software event brokers support an active/standby redundancy model. With this model, a primary event broker provides messaging services to clients, while a backup event broker waits in standby mode—it only provides service should the primary event broker fail. A third event broker acts as a monitoring node, to act as a tie-breaker and prevent split-brain scenarios that would otherwise cause both the primary and backup event broker to become active simultaneously.
