Logic Apps Designer

TypeScript/React app Uses OpenAPI (Swagger) to render inputs & outputs Generates workflow definition (JSON)

Logic App Runtime Reads the workflow definition and breaks down into a composition of tasks with dependencies Distributed compute/workers are coordinated to complete tasks on-demand At least once guaranteed execution No active thread management – tasks and runs can exist in parallel and at massive scale

Task Resiliency Transient failures invoke retry- policies (DNS issues, throttles, or 5xx responses) If the task doesn’t respond, workflow orchestrator will assign a new task (at least once guarantee)
