E-MapReduce (EMR) supports the subscription and pay-as-you-go billing methods. This topic describes the pay-as-you-go billing method.
Pay-as-you-go is a billing method that allows you to use resources before you pay for the resources. You can purchase and release resources based on your business requirements. You do not need to purchase a large number of resources in advance.
The pay-as-you-go billing method is suitable for the following business scenarios:
You can view the pricing of a pay-as-you-go EMR cluster in the order that is generated when you purchase the cluster in the EMR console.
Bills are generated on an hourly basis at the top of every hour (UTC+8). The new billing cycle starts after the bills are settled. In each hourly cycle, you are charged for resources by second (UTC+8).
If the sum of the balance and vouchers in your Alibaba Cloud account is less than the amount that you must pay, Alibaba Cloud notifies you by text message or email.
Switching to subscription
You can switch the billing method of a pay-as-you-go EMR cluster to subscription. For more information, see Switch from pay-as-you-go to subscription.
