E-MapReduce (EMR) supports the subscription and pay-as-you-go billing methods. This topic describes the subscription billing method.
Subscription is a billing method that requires you to pay for resources before you can use the resources. The subscription billing method allows you to reserve resources. Compared with the pay-as-you-go billing method, the subscription billing method is more cost-effective in most business scenarios.
The subscription billing method is suitable for the following business scenarios:
You can view the pricing of a subscription EMR cluster in the order that is generated when you purchase the cluster in the EMR console.
The billing cycle of a subscription resource is the time commitment you make when you purchase the resource. The time is based on UTC+8. The billing cycle begins at the point in time when the subscription resource is purchased or renewed, which is accurate to the second, and ends at 00:00:00 on the day after the expiration date.
The unit for the billing cycles of subscription resources is calendar years or months. Examples:
You cannot perform operations in the EMR console to request refunds of your subscription clusters.
