CloudOps Orchestration Service Use Case: Schedule Temporary Bandwidth Upgrades for Tair (Redis® OSS-Compatible) Instances

The article introduces the OOS feature that allows scheduled bandwidth upgrades for Tair (Redis® OSS-Compatible) instances to optimize performance and stability.

By Yicheng

Background Information

In today's data-driven business landscape, Tair (Redis® OSS-Compatible) has become a pivotal component of the critical infrastructure of many enterprises thanks to its excellent performance and flexibility. Tair (Redis® OSS-Compatible) is widely used in a variety of data-intensive and latency-sensitive scenarios, such as caching, session management, and message queuing. It makes significant contributions to business continuity and user experience improvement. However, during large-scale marketing campaigns, product launches, or other planned events that attract high traffic, the standard bandwidth configuration may face considerable challenges. At such crucial times, even minimal latency may lead to adverse market impacts and losses of user retention for enterprises.

To resolve the preceding issue, CloudOps Orchestration Service (OOS) provides a feature that enables scheduled upgrades to the temporary bandwidth of Tair (Redis® OSS-Compatible) instances. You can also use OOS to temporarily upgrade the bandwidth of Elastic Compute Service (ECS) instances or schedule temporary bandwidth upgrades for elastic IP addresses (EIPs). This feature allows you to plan and execute scheduled bandwidth upgrades based on business load forecasts. This ensures the performance and stability of your applications at critical moments and optimizes costs.

Key Features

  • Scheduled triggering: You can preset specific dates and times to automatically trigger bandwidth upgrades based on your business requirements.
  • Automatic reversion: Upon completion of the specified upgrade duration, the bandwidth automatically reverts to the original value. This effectively prevents cost wastes during off-peak hours.
  • Cost optimization: The bandwidth is upgraded only on demand, so enterprises can significantly reduce operational costs while maintaining service quality.
  • Streamlined operation: The user-friendly user interface (UI) design allows you to complete the bandwidth upgrade process in just a few steps.

Scenarios

  • E-commerce platform promotions: Schedule bandwidth upgrades during major promotional events to handle the surge in user traffic.
  • Large-scale game updates: Upgrade the bandwidth during new game version releases or major updates to ensure a seamless download experience for players.
  • Holiday traffic spikes: Plan ahead for bandwidth enhancement to accommodate the expected surge in visits during holidays.
  • Data-intensive tasks: Temporarily increase the bandwidth to expedite the completion of tasks such as large-scale data migrations or analytical operations.

Procedure

1.  Log on to the OOS console.

2.  In the left-side navigation pane, choose Automated Task > Public Template. On the Public Template page, enter ACS-Redis-ScheduleToUpgradeInstanceBandwidth in the search box. Find the ACS-Redis-ScheduleToUpgradeInstanceBandwidth template and click Create Execution.

3.  On the Create Task page, click Next Step: Parameter Settings. In the Parameter Settings step, configure the TimerTrigger parameter in the Timer Trigger Configure section.

You can set the TimerTrigger parameter to Execute Now, Executed Once at the Specified Time, or Executed Periodically. If you select Execute Now, the scheduled bandwidth upgrade task is executed immediately after it is created. If you select Executed Once at the Specified Time, the scheduled bandwidth upgrade task is executed only once at the specified point in time. If you select Executed Periodically, the scheduled bandwidth upgrade task is periodically executed based on the scheduled time. For example, you can specify that the scheduled bandwidth upgrade task is executed on an hourly basis.

4.  In the Select Instances section, specify the region in which your Tair (Redis® OSS-Compatible) instances reside. Select one of the following options for TargetInstance to find one or more Tair (Redis® OSS-Compatible) instances that you want to manage: Manually Select Instances, Specify Instance Tags, Specify Resource Group, Upload CSV File, and Select All. Configure the Bandwidth and DurationHour parameters. The minimum bandwidth upgrade duration is 1 hour. In the Control Options section, select a role that has access to the Tair (Redis® OSS-Compatible) instances, and click Next Step: OK. Then, click Create in the next step. Till now, the scheduled bandwidth upgrade task is created for the Tair (Redis® OSS-Compatible) instances. When the specified time arrives, the system automatically upgrades the bandwidth of the Tair (Redis® OSS-Compatible) instances. Upon completion of the upgrade duration, the bandwidth automatically reverts to the original value.
