Abstract: Systems and methods for state management and workflow completion are disclosed. An exemplary method may include receiving a request and data at an onboarding service; sending the request and data to an initiator service; initiating, by the initiator service and at a workflow orchestration engine, a workflow, wherein the workflow is initiated based on the request, and wherein the workflow includes a plurality of activities; registering, by the workflow orchestration engine, the workflow in a unique namespace; generating a worker instance in an application-level container at a compute node; sending, to the worker instance, an activity of the plurality of activities for completion of the activity by the worker instance; communicating, by the worker instance with at least one service, indicating, by the worker instance and to the workflow orchestration engine, that the activity is complete; and persisting, by the workflow orchestration engine, state data for the workflow.
