Pentaho Bursting is a feature of the Pentaho Reporting Server and the Pentaho BI Platform. As you can see from the sections above there are many components required to build a successful Report Bursting system such as:
Triggers: Business rules, events, integration points
Workflow: Ability to customize logic
Services and messaging: clustering / scalability
Business Intelligence components: reporting, rules engines, email, print, workflow integration etc
System Control: SNMP / JMX integration
Auditing: Reporting and analysis of what has been generated and delivered
The Pentaho BI Platform contains all of these components in a scalable, customizable, embeddable system that is available as an Open Source product.
