Point Domains to Load Balancers

You can load balance incoming traffic to your domain using a Cloud Load Balancer. Suppose you initially have one Cloud Server with a domain pointing to the public IP Address of the server. Then traffic to your domain starts picking up and suddenly overloads your server. To improve traffic flow, you can create a clone of the server and then put both servers behind a new load balancer. Instead of pointing your domain directly to the old server, you can now point it to the new load balancer, which will distribute the traffic evenly and prevent server overload. Additionally, you could create several new domains that point to the load balancer.

This article describes how to point an existing domain to a Cloud Load Balancer. For instructions on creating a new Load Balancer, see Configuring a Load Balancer.

Pointing an existing domain to a Load Balancer

  1. Log in to the Cloud Control Panel.
  2. Click on Networking > Load Balancers.
  3. Click on an existing load balancer to see the Load Balancer Details.

    Take note of the load balancer’s IP address. You will need it in a later step.

  4. Click on Networking > Cloud DNS.
  5. Click the gear icon next to an existing domain and select Add DNS Record.
  6. In the Add Record dialog box, select A/AAAA Record as the Record Type, and enter the load balancer’s IP address as the Target.
  7. Click Add Record.

The load balancer will now distribute the traffic evenly to the nodes that are attached to the load balancer.
