    ApsaraDB for MyBase:Elastic scaling for traffic spikes

    Last Updated:Jun 21, 2026

    This topic describes how to configure elastic scaling settings to handle traffic spikes, such as those that occur during major shopping festivals.

    Background information

    The elastic scaling feature helps you easily manage these short-term business peaks. You can temporarily increase an instance's specifications, such as its memory and CPU, to improve overall performance. At the end of the temporary adjustment period, the system automatically restores the instance to its original specifications.

    For example, an e-commerce store might average 100,000 daily visits, which can be handled by an instance with 2 CPU cores and 16 GB of memory. During a major sale, this traffic could increase to one million visits. To handle this anticipated traffic spike, you can temporarily upgrade the instance to 8 CPU cores and 64 GB of memory.

    Procedure

    1. Log on to the ApsaraDB MyBase console.

    2. In the top navigation bar, select the target region.

    3. In the navigation pane on the left, click Clusters. Find the target cluster and click Details in the Actions column.

    4. In the navigation pane on the left, click Instances. Find the target instance and choose More > Set Instance Scaling in the Actions column.

    5. On the Elastic Configuration page, configure the following parameters:
      In the Set Scale-up Resources section, use the slider or input a value to adjust the resource limits (for example, set connections from 1,200 to 100,000). Set the End time. As needed, select the required options under Restore to original specifications, and then click OK.
