Power Your Event-Driven Transformation

Solace PubSub+ Event Broker efficiently streams events and information
across cloud, on-premises and IoT environments. The “+” in PubSub+ means it supports a wide range of message exchange patterns beyond publish/subscribe, including request/reply, streaming and replay, as well as different qualities of service, such as best effort and guaranteed delivery. It’s available as an appliance, software, and a service. All options offer the same functionality and management experience.

Build an Event Mesh and Share Data Everywhere

PubSub+ lets you connect event brokers to form an event mesh—an architecture layer that allows you to dynamically route events from one application to any other application no matter where those applications are deployed (no cloud, private cloud, public cloud)—so you can connect and orchestrate microservices, push events from on-premises systems of record to cloud services, and enable digital transformation across LoBs and IoT.
