This topic describes how to modify the configurations of an Application Load Balancer (ALB) instance.
Change the zone where an ALB instance is deployed
You can change the zone where an ALB instance is deployed.
- Log on to the ALB console.
- In the top navigation bar, select the region where the ALB instance is deployed.
- On the Instances page, find the ALB instance that you want to manage, and choose in the Actions column.
- In the Modify Zone/Subnet dialog box, select a zone and a vSwitch, and then click OK.
Upgrade a basic ALB instance
You can upgrade a basic ALB instance to a standard ALB instance. However, you cannot downgrade a standard ALB instance to a basic ALB instance. For more information about the differences between basic and standard ALB instances, see Features and limits of different editions.
After a basic ALB instance is upgraded to a standard ALB instance, the billing rules for standard ALB instances are applied. For more information, see ALB billable items.
- Log on to the ALB console.
- In the top navigation bar, select the region where the ALB instance is deployed.
- On the Instances page, find the ALB instance that you want to manage, and choose in the Actions column.
- In the Edition section, select Standard and click Buy Now.
Modify the maximum bandwidth value
- When an ALB instance is not associated with an EIP bandwidth plan, the pay-by-data-transfer metering method is used. In this case, the maximum bandwidth value is 400 Mbit/s and bandwidth resources cannot be dynamically allocated. In addition, you cannot modify the maximum bandwidth value.
- When an ALB instance is associated with an EIP bandwidth plan, the maximum bandwidth value of the ALB instance is determined by the maximum bandwidth value of the EIP bandwidth plan.
- You can create an EIP bandwidth plan or modify the maximum bandwidth value of an existing EIP bandwidth plan based on your business requirements. To create an EIP bandwidth plan or modify the maximum bandwidth value of an existing EIP bandwidth plan, log on to the EIP Bandwidth Plan console.
