The vector stencils library "AWS On-Demand Workforce" contains 5 Amazon Web Services on-demand workforce icons: Amazon Mechanical Turk, Human Intelligence Tasks (HIT), Assignment / Task, Workers, Requester.
Use it to draw Amazon Web Services architecture diagrams.
Do not use simple "Mechanical Turk" to refer to Amazon Mechanical Turk. Use Amazon Mechanical Turk to describe the entire system, Amazon Mechanical Turk website for the worker website, and Amazon Mechanical Turk web service to describe the product.
The AWS icons example "Design elements - AWS On-Demand Workforce" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the AWS Architecture Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.
