Task service

This type of service has a non-agnostic functional context, which means that it contains business process logic and was created for a specific business task or process. Task services do not have a great deal of reuse potential.

Task services typically compose multiple services in their logic and are sometimes referred to as task-centric business services or business process services.

If a task service has extensive orchestration logic or is hosted within an orchestration platform, it is sometimes referred to as an orchestrated task service. Orchestration logic automates the arrangement, coordination, and management of multiple services to accomplish a task.
