Auto Scaling:Manage scaling configurations

Apply or enable scaling configurations

You can apply or enable a scaling configuration to change the instance configuration source of your scaling group. When the scale-out requirements are met, Auto Scaling creates Elastic Compute Service (ECS) instances or elastic container instances based on the new scaling configuration.

1. Go to the Scaling Configurations tab.

   1. Log on to the Auto Scaling console.

   2. In the left-side navigation pane, click Scaling Groups.

   3. In the top navigation bar, select a region.

   4. Find the scaling group whose scaling configuration you want to manage and click Details in the Actions column.

   5. In the upper part of the details page, click the Instance Configuration Sources tab.

   6. Click the Scaling Configurations tab.

2. Find the scaling configuration that you want to apply and click Apply in the Actions column.

3. In the Enable Scaling Configuration message, click OK.

Modify scaling configurations

If an existing scaling configuration cannot meet your business requirements, you can modify the scaling configuration to create the desired ECS instances or elastic container instances. To modify the scaling configuration, perform the following steps:

1. Go to the Scaling Configurations tab.

   1. Log on to the Auto Scaling console.

   2. In the left-side navigation pane, click Scaling Groups.

   3. In the top navigation bar, select a region.

   4. Find the scaling group whose scaling configuration you want to manage and click Details in the Actions column.

   5. In the upper part of the details page, click the Instance Configuration Sources tab.

   6. Click the Scaling Configurations tab.

2. Find the scaling configuration that you want to modify and click Edit in the Actions column to enter the Modify Scaling Configuration page. Perform the following steps to modify the scaling configuration based on your business requirements:

   Modify scaling configurations of the ECS type

   1. On the Modify Scaling Configuration page, modify the basic information, instance type, image, and disks of the scaling configuration as prompted.

      For information about specific parameters, see Parameters.

   2. Click Modify. In the Preview Scaling Configuration dialog box, confirm the information about the scaling configuration.

   3. Click Modify.

   Modify scaling configurations of the Elastic Container Instance type

   1. On the Modify Scaling Configuration page, modify the information about the scaling configuration as prompted.

      For information about specific parameters, see Parameters.

   2. Click Confirm Configuration. In the Confirm step, confirm the information about the scaling configuration.

   3. Click Modify.

3. Optional. Enable the scaling configuration.

   If the scaling configuration is not in the Active state, you can enable the scaling configuration by repeating Step 2 immediately after you modify the scaling configuration. You can also enable the scaling configuration at a subsequent time. For more information, see Apply or enable scaling configurations.

Delete scaling configurations

If you no longer require a scaling configuration, you can delete the scaling configuration to improve your management efficiency and free up the scaling configuration quota.

1. Go to the Scaling Configurations tab.

   1. Log on to the Auto Scaling console.

   2. In the left-side navigation pane, click Scaling Groups.

   3. In the top navigation bar, select a region.

   4. Find the scaling group whose scaling configuration you want to manage and click Details in the Actions column.

   5. In the upper part of the details page, click the Instance Configuration Sources tab.

   6. Click the Scaling Configurations tab.

2. Find the scaling configuration that you want to delete and click Delete in the Actions column.

3. In the Delete Scaling Configuration message, click OK.

Import or export scaling configurations

The import and export operations apply only to scaling groups of the ECS type. You can export scaling configurations from a scaling group to back up the configurations on your on-premises computer, or import scaling configurations into another scaling group. You can export scaling configurations from one scaling group and import them into another scaling group to increase the efficiency of creating scaling configurations.

1. Go to the Scaling Configurations tab.

   1. Log on to the Auto Scaling console.

   2. In the left-side navigation pane, click Scaling Groups.

   3. In the top navigation bar, select a region.

   4. Find the scaling group whose scaling configuration you want to manage and click Details in the Actions column.

   5. In the upper part of the details page, click the Instance Configuration Sources tab.

   6. Click the Scaling Configurations tab.

2. Export or import scaling configurations.

   Export scaling configurations

   Click Export Scaling Configurations.

   A .json file is exported. Example: configuration-2024-01-29-a0c6ffb8-a3ac-4097-b145-92a722b1****.json.

   Import scaling configurations

   1. Click Import Scaling Configurations.

   2. In the Select File section, click Select File .. to select the .json file that you want to import.

      Important

      You can import up to 9 scaling configurations at the same time. The scaling configurations that you import into a scaling group do not overwrite the existing scaling configurations in the scaling group. Make sure that the network configurations, such as the network type, VPC, and vSwitch, of the source scaling group are the same as the network configurations of the destination scaling group. If the network configurations are different between the scaling groups, ECS instances may fail to be created based on the imported scaling configurations.

   3. In the Preview section, select the scaling configurations that you want to import.

      Note

      If you cannot select the scaling configurations in the Preview section, check whether the source and destination scaling groups use different network types or VPCs.

   4. Optional. To prevent duplicate scaling configuration names in the scaling group, select Add a suffix for imported scaling configurations.

   5. Click Import. If the import is successful, click OK in the message that appears.

   6. Optional. After the import is complete, put an imported scaling configuration into the Active state based on your business requirements. For more information, see Apply or enable scaling configurations.
