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 or UDP listeners added to a network load balancer.
• Upgrade or downgrade the 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): New connections may not be able to be established and some persistent connections may be interrupted.

Changing an AZ

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

1. Log in to the management console.
2. In the upper left corner of the page, click and select the desired region and project.
3. Click in the upper left corner to display Service List and choose Networking > Elastic Load Balance.
4. On the Load Balancers page, locate the load balancer, click More in the Operation column, and select Change AZs.
5. Select one or more new AZs and click Next.
6. Confirm the information and click Submit.

Changing AZs will temporarily affect services. New connections may not be able to be established and some persistent connections may be interrupted. If this happens, try again to restore the connections.
