![]() When implementing business processes, there is usually a large gap between the business semantics (process, activity, participant, orchestration, choreography, data items etc.) and the technical implementation languages (REST, WSDL, transport protocol, message bus etc.). Overview of Business Process Model and Notation (BPMN) language for modeling business processes. A prototypical modeling tool supports the strong link between the management plan and the TOSCA topology.Business Processing Model and Notation (BPMN) Description Portability is ensured by a transformation of BPMN4TOSCA to plain BPMN. To simplify the modeling of management plans, we introduce BPMN4TOSCA, which extends BPMN with four TOSCA-specific elements: TOSCA Topology Management Task, TOSCA Node Management Task, TOSCA Script Task, and TOSCA Data Object. This paper analyzes TOSCA with the focus on requirements on workflow modeling languages to come up with a strong link to the application topology with the goal to improve modeling support. There is, however, no tailored support for management plans in BPMN. BPMN 2.0 as general-purpose language can be used to model these workflows. Management plans capture these aspects in workflows. Management aspects include provisioning, operation and deprovisioning of an application. ![]() Abstract: TOSCA is an upcoming standard to capture cloud application topologies and their management in a portable way.
