    Description

    Billing overview

    Subscription is a prepaid billing method where you pay for resources before you use them. By reserving resources in advance, you receive significant price discounts and maximize cost savings.

    Use cases

    Subscription is ideal for the following scenarios:

    • Workloads with predictable usage periods.

    • Stable business workloads.

    • Long-term resource requirements.

    Pricing

    You can view the subscription pricing for E-MapReduce in the EMR console. The final cost is based on the price shown on the purchase page.

    Billing cycle

    A billing cycle is the duration you commit to when placing an order. All times are in UTC+8. A billing cycle starts the moment a resource is created or renewed and ends at 00:00:00 on the day after its expiration date.

    Note

    Billing cycles measured in years or months refer to calendar years and calendar months. For example:

    • If you purchase a subscription EMR cluster for a three-month term at 10:23:30 on January 1, 2023, the cluster expires at 00:00:00 on April 2, 2023.

    • If your subscription cluster contains pay-as-you-go resources, the ECS instance fees and EMR service fee for those resources are billed using the pay-as-you-go billing method. For more information, see pay-as-you-go.

    • If your subscription cluster has node groups with auto scaling rules, the ECS instance fees and EMR service fee for the auto-scaled resources are billed using the pay-as-you-go billing method. For more information, see Create custom auto scaling policies.

    Refund policy

    You can request refunds for subscription clusters that have not expired. For more information, see Refunds.

    Overdue payments

    To learn what happens when a payment becomes overdue, see Overdue payments.

    Impact of EMR instance expiration

    When the EMR instance for a subscription cluster expires, the following operations are restricted:

    • Service-related operations, such as adding, restarting, stopping, and configuring parameters.

    • User management operations.

    • Auto scaling operations.

    • Node-related operations, including scale-out, scale-in, and scale up.

    • Display of Application Performance Management (APM) information.

    • Bootstrap action and script operations.
