E-MapReduce:Subscription

When to use subscription

Choose subscription when your workload meets all of the following conditions:

• Resource usage is predictable — you can estimate usage duration in advance.

• Demand is stable — usage does not fluctuate significantly over time.

• Resources are needed long-term — you plan to run the instance continuously.

For short-lived or variable workloads, pay-as-you-go is more cost-effective.

Billing rules

Subscription fees are calculated per billing component based on the reserved quantity and subscription duration.

For a full list of billable items, see Billable items.

Billing cycle

The billing cycle is measured in the UTC+8 time zone. It starts at the second the subscription instance is created or renewed, and ends at 00:00:00 on the day after the expiration date.

Expiration and release

When a subscription instance expires, it is immediately suspended. If not renewed within 7 days (168 hours), the system automatically releases the instance. After the instance is released, you cannot renew it.

Renew the instance before it expires or is released to avoid service interruption. For renewal options, see Renewal policy.

Billing examples

The following examples show how to calculate subscription fees for different instance types. All examples use a 1-month subscription duration.
