In their own words
Solace PubSub+ Event Broker
Solace PubSub+ Event Broker streams information among applications, AI agents, and devices across cloud, on-premises, and edge environments. Multiple brokers can form an event mesh to route data across clouds, data centers, and geographies. It is offered as a cloud service, software, or appliance, for deployment in clouds, data centers, and remote locations. Messaging features include exchange patterns, qualities of service, caching, partitioned queues, and replay. Supported protocols include AMQP, Kafka, MQTT, REST, and WebSocket, alongside APIs for programming languages. Solace offers supported micro-integrations for applications, cloud services, and integration tools. Monitoring includes custom dashboards and alerts, and distributed tracing is broker-native and based on OpenTelemetry. Cloud services enable secure protocol ports by default and disable plain-text ports by default. Free options include a 30-day cloud trial and a free enterprise-grade software version. Solace was founded in 2001 and is headquartered in Ottawa, Ontario, Canada.
