MaxCompute:Pay-as-you-go Spot edition

Scenarios

The Pay-as-you-go Idle Edition is suitable for jobs that require very low costs but are not sensitive to completion time. For example, this edition is ideal for analyzing low-value, massive data, such as behavioral logs and system logs. These workloads typically consume a large amount of compute resources but are not sensitive to completion time. In this scenario, using subscription resources can result in idle dedicated resources, while using the Pay-as-you-go is too costly. The less sensitive a job is to its completion time, the more computing costs you can save using the Pay-as-you-go Idle Edition. However, the Pay-as-you-go Idle Edition is not recommended for production jobs that require long-term stability and guaranteed resources. This is because resource competition can cause job resources to be constrained or preempted, which may result in long wait times, increased runtimes, or even forced termination. This can in turn affect your business operations.

Resource Details

When you enable the pay-as-you-go Spot Edition, you gain access to MaxCompute idle-time compute resources (os_SpotQuota). These are shared, pay-as-you-go compute resources. Jobs that run on these resources are called Spot jobs. Compared with jobs that use the pay-as-you-go , Spot jobs have a lower unit price. This helps you reduce costs for development, testing, and other latency-insensitive scenarios.

Supported Regions

The pay-as-you-go Spot Edition is currently available in the following regions:

China (Hangzhou), China (Shanghai), China (Beijing), China (Shenzhen), China (Hong Kong), Singapore, UK (London), Japan (Tokyo), Malaysia (Kuala Lumpur), Germany (Frankfurt), Indonesia (Jakarta), US (Virginia), and US (Silicon Valley).

Billing Details

• For more information about billing details and the billing rules for the pay-as-you-go , see Compute Costs (Pay-as-you-go).

• For more information about switching between the MaxCompute pay-as-you-go Spot Edition and other compute resource types, see Switch between billing methods.

Important Notes

• You must enable the pay-as-you-go before you can enable the Spot Edition. For more information about the pay-as-you-go , see Pay-as-you-go .

• The Spot Edition covers only compute resources. Storage and download fees are charged based on the pricing of the pay-as-you-go .

Usage Instructions

1. Enable the MaxCompute pay-as-you-go .

   For information about the steps to enable the pay-as-you-go , see Enable MaxCompute.

2. Enable the MaxCompute pay-as-you-go Spot Edition.

   Go to the Alibaba Cloud MaxCompute pay-as-you-go Spot Edition activation page. Set the Product Type parameter to Pay-as-you-go Spot Edition. Configure the Region parameter as prompted, read and select the Terms of Service check box, and then click Activate Now.

   Important

   You cannot unsubscribe after you activate the Spot Edition. If you do not run jobs that use MaxCompute idle-time compute resources (os_SpotQuota), you are not charged for the Spot Edition.

3. View your pay-as-you-go Spot Edition compute resources.

   1. Log on to the MaxCompute console and select the region in which you activated the Spot Edition from the top navigation bar.

   2. In the navigation pane on the left, choose Manage Configurations > Quotas.

   3. On the Quota Management page, check whether the primary quota os_SpotQuota_p and the secondary quota os_SpotQuota are displayed. If they are displayed, you can use the Spot Edition compute resources.

4. Attach Spot Edition compute resources to a project.

   • For new projects, set the Default Quota parameter to os_SpotQuota when you create the project.

   • For existing projects, go to the Project Management page, click Manage in the Actions column of the target project, and then on the Project Configuration page, switch to the Parameter Settings tab and change the value of the Default Compute Quota parameter to os_SpotQuota.

5. Run a Spot job (SpotJob).

   By default, jobs that are submitted in a project that is bound to os_SpotQuota are Spot jobs. However, if you specify another runtime quota, such as the default pay-as-you-go quota, before the query, the job runs as a standard job.

   Similarly, in a project that is not bound to os_SpotQuota, you can still run a Spot job by adding the following command before your query to explicitly set the compute quota to os_SpotQuota:

   set odps.task.wlm.quota=os_SpotQuota;

   For more information about how to specify a quota at the job level, see Specify Quota at the job level.

   Important

   Successful Query Acceleration (MCQA) jobs cannot use this command to specify a compute quota. The resource consumption of these jobs is always billed based on the default compute quota that is attached to the project where the job runs. This applies to jobs such as query acceleration jobs that are initiated from or from DataWorks by creating ad hoc queries.

6. Monitor the job status and resource consumption.

   You can use the job O&M feature in the MaxCompute console to view historical and running jobs. For more information, see Manage jobs. You can use the Quota Management feature to monitor the usage of idle-time compute resources. For more information, see View Quota consumption.

   Note

   Monitoring the resource consumption of query acceleration jobs is not supported.

7. You can view your pay-as-you-go off-peak consumption details.

   For more information about how to view the consumption and usage details for the MaxCompute pay-as-you-go Spot Edition, see View bill details.
