I have been using an A record for my domain to point to Acquia balancers now I need to use an Edge Cluster.
The balancer layer for your sites hosted on Acquia Cloud has been improved, and now provides High Availability as standard. To set up your DNS to take advantage of the High Availability provided with the balancer layer, you need to do the following:
- For root domains (e.g. example.com) you need to implement two A Records with the two IP’s.
- For submains (e.g. www.example.com) you have the option of implementing two A Records with the two provided IP’s, or a single CNAME Record.
The root domain is pointed at two A records and the subdomain is pointed as a CNAME record:
example.com A Record 123.456.789.01 example.com A Record 123.456.789.02 www.example.com CNAME Record example.prod.acquia-sites.com
Both the root domain and the subdomain is pointed at the two A records as well:
example.com A Record 123.456.789.01 example.com A Record 123.456.789.02 www.example.com A Record 123.456.789.01 www.example.com A Record 123.456.789.02
