    E-MapReduce:Computing resource (subscription)

    Last Updated:Aug 28, 2026

    Subscription is a prepaid billing model for computing resources. The total price is determined by the number of CUs, the unit price, and the subscription duration.

    Subscription

    Feature

    Description

    Applicable scenarios

    Subscription is recommended for the following scenarios:

    • Long-term, stable workloads: Cost-effective for consistent, long-running workloads such as Spark Streaming jobs or persistent Kyuubi and Livy services.

    • Predictable budgeting: Prepaying locks in costs and eliminates billing uncertainty from fluctuating usage.

    Billing rules

    The total price of a subscription quota is calculated as follows: Number of CUs × Unit price × Subscription duration.

    Important

    In this formula, the subscription duration is measured in months. Refer to your bill for the final charges.

    For example, in the Singapore region, the unit price for a computing resource is USD 32.21/CU/month. If you purchase a subscription quota of 100 CUs for a workspace for 6 months, the total fee is 100 CUs × USD 32.21/CU/month × 6 months = USD 19,326.

    Billing cycle

    The billing cycle starts at the exact second the subscription is activated or renewed (UTC+8) and ends at 00:00:00 on the day after the expiration date.

    Renewal

    Renew your subscription quota before it expires to avoid service interruptions. For more information, see Renewal rules.

    Note

    • If you do not renew before expiration, jobs submitted to the subscription resource queue stop running. Renew promptly to avoid disruptions.

    • If your account has an overdue payment, automatic renewal may fail. Top up your account and renew the subscription manually.

    Refunds

    If you no longer need the subscription quota, unsubscribe from it in the Expenses and Costs console. For more information, see Unsubscription and refunds.

    Upgrade

    Increase your subscription quota at any time to meet growing business needs. For more information, see Upgrade subscription quota.

    Downgrade

    Decrease your resource quota if your business needs change. For more information, see Downgrade subscription quota.
