Scaling EIP Bandwidth Based on Demand

AS adjusts bandwidth for an application system based on demand, thereby enhancing cost management.

You can select the following scaling policies to adjust the IP bandwidth based on site requirements:

  • Alarm Policy

    You can set the alarm triggering conditions such as outbound traffic and bandwidth. When the system detects that the triggering conditions are met, the system automatically adjusts the bandwidth.

  • Scheduled Policy

    The system can automatically increase, decrease, or adjust the bandwidth to a fixed value at a fixed time according to the scheduled policy.

  • Periodic Policy

    The system can periodically adjust the bandwidth based on the periodic policy, reducing the workload of manually setting the bandwidth.

The following uses the alarm policy as an example:

For example, the service load changes of a live video website in different time periods are difficult to predict. Therefore, the bandwidth needs to be dynamically adjusted between 10 Mbit/s and 30 Mbit/s based on metrics such as outbound traffic and inbound traffic. AS can automatically adjust the bandwidth to meet requirements. You need to select the target EIP and create two alarm policies. One policy is to add 2 Mbit/s when the outbound traffic is greater than xxx bytes, with the limit set to 30 Mbit/s. The other policy is to reduce 2 Mbit/s when the outbound traffic is less than xxx bytes, with the limit set to 10 Mbit/s.
