Pay-As-You-Go Instance Modify Bandwidth


Update time: 2022-05-19 14:30
For pay-as-you-go instances that use fixed public IP addresses, if you find that the public network bandwidth cannot meet or exceed business requirements, you can modify the public network bandwidth.

Background Information
The function of modifying bandwidth on a per-volume basis supports the following operations. After the modification is successful, it cannot be modified again within 5 minutes.
To change the billing method for public network bandwidth, choose fixed bandwidth or used traffic.
Modify the fixed bandwidth size or the peak traffic bandwidth according to the bandwidth billing method.
Note If the public network bandwidth is set to 0 Mbit/s during modification, if the instance is on a classic network, the fixed public network IP address will still be reserved. If the instance is a VPC, the fixed public IP address will be automatically released.
This document describes how to modify the bandwidth of a pay-as-you-go instance that uses a fixed public IP. If the instance uses an elastic public IP, see Changing the EIP Bandwidth.

single change bandwidth
Log in to the ECS management console.
In the left navigation bar, click Instances & Images > Instances.
In the upper left corner of the top menu bar, select Territory.
Find the pay-as-you-go instance, and in the Actions column, click More > Resource Change > Change Bandwidth for Pay-As-You-Go Instances.
Find the configuration item corresponding to the public network bandwidth on the pop-up page, and change the peak bandwidth as needed.
Select the public network bandwidth billing method as per fixed bandwidth or per usage flow.
Set the corresponding fixed bandwidth size or peak traffic bandwidth.
Read the precautions and terms of service below, and if there is no problem, select "Cloud Server ECS Terms of Service".
Confirm the fee, click Confirm Change, and follow the instructions on the page to complete the follow-up operations.
NOTE Generally, after the change is completed, the new public network bandwidth setting takes effect immediately. However, if you upgrade the public network bandwidth of a classic network instance from 0 Mbit/s to a non-zero value for the first time, you must restart the instance on the console or use the API RebootInstance for the new configuration to take effect.

Bandwidth modification for annual and monthly instances


Update time: 2022-06-13 09:47
For annual and monthly subscription instances that use a fixed public network IP, you can modify the public network bandwidth if you find that the public network bandwidth cannot meet or exceed business requirements.

Preconditions
If you need to use the configuration reduction function to reduce the fixed bandwidth or change the peak traffic bandwidth, please first confirm that the account where the instance is located has the function privilege of real-time downgrade.
NOTE You can click on Equity Quota on the overview page of the ECS management console, and then check whether the account has the function privilege of real-time downgrade. If you need the function privilege of real-time downgrade, please submit a ticket.
Background Information
Depending on the bandwidth billing method, you can modify the fixed bandwidth size or the peak traffic bandwidth.
When the current public network bandwidth billing method is fixed bandwidth, you can upgrade or reduce the fixed bandwidth size. For details, see Upgrading Fixed Bandwidth or Decreasing Fixed Bandwidth.
Note Reducing the fixed bandwidth may result in a refund. The refund amount is the difference between the newly configured price and the remaining price of the valid purchase before the downgrade. A maximum of 3 refunds can be made for each annual and monthly subscription instance. The real-time downgrade function is used to reduce the instance specification configuration, reduce the bandwidth configuration, or switch to pay-as-you-go through cloud disk payment, and the number of times will be consumed when the refund is generated.
When the current public network bandwidth billing method is based on traffic usage, you can change the bandwidth peak value. For details, see Changing the Traffic Bandwidth Peak.
Modifying the public network bandwidth of an instance has the following functional limitations:
Whether or not to downgrade the bandwidth depends on your cloud server usage.
For the same instance, the interval between two modify bandwidth operations must be at least 5 minutes.
This document describes how to modify the bandwidth of an instance that uses a fixed public IP address. If the instance uses an elastic public IP address, see Changing the EIP Bandwidth.

Upgrade Fixed Bandwidth
If your current public network bandwidth billing method is fixed bandwidth, you can upgrade the fixed bandwidth in the following ways.

Note If you did not purchase public network bandwidth when you created an instance, that is, did not assign a public network IP address, you can assign a public network IP address by upgrading the fixed bandwidth and setting the public network bandwidth to a non-zero value.
Log in to the ECS management console.
In the left navigation pane, choose Instances & Images > Instances.
In the upper left corner of the top menu bar, select Territory.
Choose one of the following methods to enter the configuration page.
Single upgrade bandwidth
Find the annual and monthly subscription instance to be operated, and in the Operation column, click Upgrading and Upgrading.
In the dialog box that pops up, select Upgrade Configuration and click Continue.
Batch upgrade bandwidth
Select the annual and monthly subscription instance to be operated, and click More > Resource Configuration > Subscription Instance Change Bandwidth at the bottom of the page.
In the pop-up dialog box, select Upgrade Fixed Bandwidth, and then click Continue.
Find the configuration item corresponding to the public network bandwidth on the configuration page, and upgrade the bandwidth as needed.
During batch operations, if the selected instances do not meet the requirements of using a fixed public network IP and bandwidth is billed by fixed bandwidth, they will be automatically filtered, and only the instances that meet the requirements can continue to be operated.
