Tair (Redis® OSS-Compatible):Schedule temporary bandwidth upgrades for Tair or Redis instances

Background information

Scheduled bandwidth upgrades have the following features:

• Scheduled triggering: You can preset specific dates and times to automatically trigger bandwidth upgrades as needed.

• Automatic recovery: After the specified duration elapses, the bandwidth automatically reverts to the original value. This effectively prevents cost wastes during off-peak hours.

• Cost optimization: You can use OOS to upgrade the bandwidth on demand and help enterprises to significantly reduce operational costs while maintaining service quality.

• Streamlined operation: The user-friendly interface lets you complete the bandwidth upgrade settings in just a few steps.

The following table describes the characteristics and applicable scenarios of the three bandwidth upgrade methods supported by Tair and Redis.

Prerequisites

You need to create a RAM role for OOS to access ApsaraDB for Tair (Redis OSS-compatible) service. For more information, see Create a RAM role for OOS and grant permissions.

• You can grant the system policy AliyunKvstoreFullAccess to the role. After authorization, the RAM role can manage all resources of ApsaraDB for Tair (Redis OSS-compatible).

• You can also customize a least privilege policy (allowing OOS to call the DescribeInstances and EnableAdditionalBandwidth APIs of ApsaraDB for Tair (Redis OSS-compatible)) to limit the role to executing only the current task.

  Example of a policy attached to a RAM role:

  {
      "Version": "1",
      "Statement": [
          {
              "Effect": "Allow",
              "Action": [
                  "kvstore:DescribeInstances",
                  "kvstore:EnableAdditionalBandwidth"
              ],
              "Resource": "*"
          }
      ]
  }

Procedure

1. Visit the OOS console.

2. In the navigation pane on the left, choose Automated Task > Common O&M Tasks.

3. Select Temporary Bandwidth Upgrade and click Create.

4. Configure the O&M task.

   Note

   This topic only introduces the key steps. For other parameters, see CloudOps Orchestration Service.

   Select resource type

   Select ApsaraDB For Redis Instance.

   Parameters settings

   1. Select Scheduled Task Type.

      In this example, select Executed Periodically, specify execution at 11:00 every day, and specify the cycle start and end times.

      

   2. Select Additional Bandwidth in MB/s.

      • For standard architecture, you do not need to specify the data shard ID.

      • If the instance uses cluster or read/write splitting architecture, the default value of the data shard ID is ALL, which means that the corresponding bandwidth is added to each shard or node. The total additional bandwidth is calculated using the formula: Additional Bandwidth × Number of shards (nodes).

        If you want to increase the bandwidth for specific shards only, you can enter multiple data shard IDs separated by commas (,). At the same time, add the corresponding number of Bandwidth Arrays and enter the bandwidth values to be added in the order of the data shard IDs.

   3. Select Duration Of Bandwidth Upgrade in hours.

      The minimum duration is 1 hour. After the duration elapses, the instance bandwidth will revert to the default configuration.

   4. In Permissions, select the RAM role that you created in the Prerequisites section.

   Select instances

   Select the region where the desired instance resides and select the instance.

   Advanced options (optional)

   You can use the default values for the parameters on this tab.

   Execution settings (optional)

   You can use the default values for the parameters on this tab.

5. Click Create and click OK in the dialog box.

   When the Execution Status shows Active, it indicates that the task will be automatically executed according to the Timer Trigger Configure.

   You can view historical execution tasks, upcoming execution tasks, and Execution Logs on the task details page.
