Asynchronous service in Dynamics 365 Customer Engagement
The asynchronous service executes long-running operations independent of the main Dynamics 365 for Customer Engagement core operation. This results in improved overall system performance and improved scalability. The asynchronous service features a managed queue for the execution of asynchronous registered plug-ins, workflows, and operations such as bulk mail, bulk import, and campaign activity propagation. These operations are registered with the asynchronous service and executed periodically when the service processes its queue. The asynchronous service can be hosted on a server other that the server running Dynamics 365 Customer Engagement (on-premises).
