This topic describes the basic resources, billing rules, and usage notes for the subscription billing method of MaxCompute.
Basic resources
The following table describes the basic resources of the subscription billing method.
Basic resource | Description | Billing rule |
Computing resources | A dedicated resource pool is provided. The resources are allocated based on the number of compute units (CUs) that you purchase. For projects that use the subscription resource package, only resources that are dedicated to the projects are consumed to execute computing jobs, such as SQL jobs that use user-defined functions (UDFs), MapReduce jobs, Spark jobs, and Graph jobs. | You must purchase at least 50 CUs when you activate MaxCompute. For more information about the billing rules, see Computing pricing. |
Usage notes
For more information about how to activate MaxCompute that uses the subscription billing method, see Activate MaxCompute.
After you purchase subscription computing resources, take note of the following items:
When you create a project and configure default computing resources in the region in which the subscription MaxCompute service is activated, you can select the subscription computing resources. You can also configure rules on the Quotas page in the MaxCompute console or specify a subscription quota when you submit a job to use subscription computing resources. For more information, see Use of computing resources.
If the CUs that you purchase are insufficient, you can increase the number of CUs. If multiple CUs are idle, you can decrease the number of CUs. Example:
If Alibaba Cloud account A purchases 100 subscription CUs in the China (Hangzhou) region, Alibaba Cloud account A has a computing resource pool that contains 100 CUs in the China (Hangzhou) region.
If the projects in the region use the subscription resource package, the computing jobs of the projects use resources in the resource pool that has 100 CUs by default.
If computing jobs use less than 100 CUs, the other CUs remain idle. If computing jobs require more than 100 CUs, the jobs use the 100 available CUs. The time required to execute jobs is extended because resources are insufficient. For more information about how to increase or decrease the number of CUs, see Upgrade or downgrade resource configurations.
After you purchase subscription computing resources, you can manage the resources, monitor the system status and jobs, and allocate resource groups in the MaxCompute console. For more information, see Manage quotas in the new MaxCompute console.
