Schedule bandwidth upgrades for EIPs - CloudOps Orchestration Service

This topic describes how to use CloudOps Orchestration Service (OOS) to plan and schedule temporary bandwidth upgrades for elastic IP addresses (EIPs). This ensures the performance and stability of applications during critical periods and reduces costs.

Background information

As business grows and Internet scenarios become more diversified, enterprises and individual users more commonly encounter significant spikes in network traffic within a specific period of time. Such spikes, driven by events such as large-scale promotional campaigns, popular live streaming events, major news announcements, or seasonal data backup activities, can quickly saturate existing bandwidth. This adversely affects user experience and potentially causes service interruptions. Traditional network bandwidth configurations often fail to handle these sudden spikes, and maintaining high bandwidth levels over the long term is prohibitively expensive. If you seek to balance cost with network performance, you may face a significant challenge.

To resolve the preceding issues, OOS introduces the feature of scheduled temporary bandwidth upgrades. OOS already supports temporary bandwidth upgrades. OOS now offers the scheduled bandwidth upgrade feature specifically for scenarios in which EIPs are used. This feature provides a flexible solution that allows you to temporarily increase bandwidth based on business requirements during a specific period of time in anticipation of business peaks. This enables proactive planning for expected traffic surges and automatically restores bandwidth to the original value after the peak period, thus reducing unnecessary additional costs.

Benefits

Scheduled triggering: You can preset specific dates and time for automatic bandwidth upgrades to be executed based on the schedule, which eliminates the need for manual intervention.
Automatic reversion: After the upgrade duration elapses, the bandwidth automatically reverts to the original value to reduce unnecessary costs.
Cost optimization: You can upgrade bandwidth based on your business requirements to significantly reduce operational costs and maximize resource utilization.
Simplified operation: The OOS console provides a user-friendly GUI that allows you to configure scheduled bandwidth upgrades with only a few steps.

Scenarios

Big sales promotions on e-commerce platforms

During e-commerce industry promotions at year-end and on specific holidays, website traffic dramatically surges. By using the scheduled bandwidth upgrade feature, e-commerce platforms can preset bandwidth upgrades ahead of time to ensure smooth customer access, thereby improving the shopping experience and increasing conversion rates.

Live classes on online education platforms

Online education platforms experience a rapid increase in user traffic during large-scale free public classes or live sessions with renowned instructors. By using the scheduled bandwidth upgrade feature, online education platforms can ensure that adequate network bandwidth is available during live streaming events, thereby facilitating the smooth delivery of courses.

Game releases and updates

When gaming companies launch new titles or roll out major updates, a concentrated influx of players downloading the update packages can cause a significant bandwidth spike. By using the scheduled bandwidth upgrade feature, gaming companies can offer stable download services during these critical periods, thereby improving the player experience.

Periodic data backup

For enterprises that need to undertake large-scale data migration or backups, using the scheduled bandwidth upgrade feature can ensure consistent network speed during the data transfer period. This helps shorten the backup time window and minimize the impact on business operations.

Note

Only pay-as-you-go EIPs support temporary bandwidth upgrades.
You can temporarily upgrade only the public bandwidth that is charged by using the pay-by-bandwidth billing method. You cannot temporarily upgrade the public bandwidth that is charged by using the pay-by-data-transfer billing method.

Procedure

Log on to the CloudOps Orchestration Service console.
In the left-side navigation pane, choose Automated Task > Common O&M Tasks. On the Common O&M Tasks page, click Temporary Bandwidth Upgrade and click Create.
On the Create Task Temporary Bandwidth Upgrade page, select EIP for Resource Type and configure the parameters.
- On the Create Task Temporary Bandwidth Upgrade page, select EIP for Resource Type and configure the parameters.
- Bandwidth (Mbit/s): Enter the maximum bandwidth of the instance. Valid values: 1 to 500. You are charged on a pay-by-bandwidth basis. Unit: Mbit/s.
- Duration of Bandwidth Upgrade: Unit: hours. You must specify a value that is greater than 1.
- Permissions: To perform a temporary upgrade, you must grant the related permissions to the role assumed by OOS. For more information about how to create a role, see Use RAM to grant permissions to OOS.
