Messaging service for Pega Constellation
The Pega Constellation messaging service intermediates between the case engine and UI components in browsers that act as information publishers and subscribers. The new service accepts HTTP-based information and forwards it to WebSocket subscribers.
A third-party integration service can also act as a publisher.
The following diagram represents the messaging service architecture.
An IP address exposes the messaging service to browsers and publishers. The URL for the service is passed to the browser during the initial portal load from the dynamic system settings in Pega Platform. The publishers and subscribers use the same IP address for HTTP POST calls and WSS connections.
For more information about installing and configuring the service, see the Constellation messaging installation site with advanced developer documentation.
