You can resolve a domain name to the public address of the Server Load Balancer instance. For example, the domain name of your website is www.abc.com and the website is running on an ECS instance with the public IP 188.8.131.52. After creating a Server Load Balancer instance, a public IP 184.108.40.206 is allocated to the instance. You have to add the ECS instance hosting the website to the backend server pool and resolve the domain name www.abc.com to 220.127.116.11. We recommend that you add an A record resolution (resolve a domain to an IP address).
