Deployments of Pega Platform integration services that are part of highly available production environments require additional configuration that might not be necessary in development.
Be mindful of high availability when you deploy listeners, service packages, service request processors, and service rules.
Listeners are background processes in the Pega Platform that wait for inbound network requests or messages. In a high availability environment, listeners should be distributed across hosts and Pega Platform servers by using node types to assure redundancy.
- Service packages
A service package is a Pega Platform data instance for a collection of services. It controls access to the listeners for the services with defined Pega Platform Access Groups. The service package also defines the service processing mode (stateless or stateful) and pooling options for stateless unauthenticated services.
- Service request processors
Service request processors are also Pega Platform data instances that provide configuration options for asynchronous processing.
- Service rules
The processing of service requests is handled by service rules as appropriate for each service type.
