Connection Scaling Tiers

The Solace PubSub+ software message broker's connection scaling tier sets the maximum number of concurrent client connections that the PubSub+ Standard and Enterprise products can support. By default they support a maximum of 100 connections, but other scaling tiers are available that offer increased client connections when you provision sufficient system resources; however, it should be noted that PubSub+ Standard supports a maximum of 1,000 client connections regardless of the provisioned system resources.

When the connection scaling tier is increased, many of the message broker's other operating limits (for example, the maximum permitted number of client usernames, subscriptions, and Guaranteed Messaging flows) are automatically scaled to appropriate values.
