E-MapReduce (EMR) Workflow is available in public preview from June 29, 2023 through January 10, 2024. All users can participate at no charge for the workflow service itself.
To access EMR Workflow, log on to the EMR console and choose EMR Studio > Workflow in the left-side navigation pane.
Billing
EMR Workflow is free during the public preview. However, running workflows requires an associated EMR cluster. Charges apply for the Elastic Compute Service (ECS) instances and the EMR service if you create or use an existing EMR cluster. For details, see Billable items.
