The Solace PubSub+ software event broker efficiently transfers event-driven information between applications, IoT devices and user interfaces running in cloud, on-premises, and hybrid environments. The software event broker lets you leave lock-in behind by using open APIs and protocols like AMQP, JMS, MQTT, REST and WebSocket. It's available for installation into a variety of clouds, all regions of AWS, PaaS, and on-premises environments.
The pages in this section show you how to set up and run Solace PubSub+ software event brokers in a range of common cloud services and hypervisors, and also provide instructions on how to configure those event brokers for a variety of uses.
Solace offers the following editions of the software event broker:
- Standard: Free and full-featured.
- Enterprise: High-performance, full scale, enterprise-ready, and production deployable.
With SolOS version 9.13.1 or later, you can do a 90-day evaluation of the Enterprise edition by installing the Standard edition and entering a free product key. To get the product key, go to solace.com/downloads and select PubSub+ Enterprise Evaluation.
If you are using SolOS 9.13.0 or earlier, first upgrade your Standard edition broker to the latest version from solace.com/downloads (following the standard-to-standard upgrade procedure), then install the product key after the upgrade is complete.
For help or more information, contact Solace.
After the Enterprise Evaluation key is installed, the event broker will cease to function after 90 days, and all configuration will be lost unless you upgrade to the Enterprise edition prior to the 90 day expiration. Contact Solace for assistance.
For instructions for installing product keys, see Product Keys .
