Modifying the Basic Configurations of a Dedicated Load Balancer

Modifying Specifications

You can change the specifications of a dedicated load balancer on the console:

• Change the elastic specifications to fixed specifications, or the other way round.
• Change the application load balancing to network load balancing, or the other way round.

  You must keep at least one load balancing type. Before removing a load balancing type, you must delete the:

  • HTTP or HTTPS listeners added to an application load balancer.
  • TCP, TLS, or UDP listeners added to a network load balancer.
• Upgrade or downgrade the fixed specifications, for example, upgrade small I to medium I, or downgrade large I to medium I.

Change options vary by billing mode. To find out what changes you can make, see Table 1.

• Upgrading specifications does not interrupt your services.
• Downgrading specifications will temporarily disconnect services.
  • Network load balancing (TCP/UDP): New connections may not be able to be established.
  • Application load balancing (HTTP/HTTPS/TLS): New connections may not be able to be established and some persistent connections may be interrupted.

Changing an AZ

You can change the AZs of a dedicated load balancer as required on the console.

After the AZ is changed, traffic will be distributed to the new AZ.

You can only deploy the load balancer in an additional AZ but cannot remove it from an AZ.

This feature will be available in more regions. See details on the management console.

1. Go to the load balancer list page.
2. On the displayed page, locate the load balancer, click More in the Operation column, and select Change AZs.
3. Select one or more new AZs and click Next.
4. Confirm the information and click Submit.

You are advised to change the AZ during off-peak hours. Changing AZs will temporarily affect services. New connections may not be able to be established and some persistent connections may be interrupted.
