What is Load Balancing?
Load balancing, also known as a Round Robin configuration, allows you to distribute traffic loads evenly among multiple servers. Simply create multiple records with the same name, but with different associated IP’s/hostnames/target servers. In this tutorial, we will be demonstrating how to create a Round Robin configuration using A records. You can apply the same steps and principles to all other record types.
1. Click Domains
Navigate to Managed DNS > Domains.
2. Select Your Domain
Select the Domain Name you want to add a Round Robin configuration to.
3. Add Record
Find the Record Type you want to create a Round Robin configuration for. For this tutorial, we want to create Round Robin for an A record. So, under the A Records section, we will click the "+" to add a record.
4. Configure Round Robin
For detailed information on how to set up an A record, click here.
IP Address: The IPv4 address of your FQDN. An IP (Internet Protocol) address consists of a four-octet 32-bit address.
Add Another IP: Click the Add Another IP button. You can add as many IP’s as you want to this record. Enter a second IP address for the A record to point to. Traffic will be split evenly between both hosts. You can click the slider to disable one of the records at any time.
Enabled: This option allows you to manually remove an IP from the round-robin configuration and add it back with ease.
If you want to create Round Robin but with the traffic load distributed unevenly, refer to the Weighted Round Robin tutorial. You can also configure Round Robin with DNS Failover, learn in this tutorial.
