BIG-IP DNS assists with various kinds of queries when the A type query is used extensively. A BIG-IP DNS gets a query by matching the domain name and type with a wide-IP, then it chooses a pool (GSLB pool) to justify the response. Then it gets a virtual server from the pool by reacting with an IP address. GSLB pool will help in choosing a virtual server across both sites based on the load-balancing policy on each site and resources availability at runtime.

BIG-IP DNS high-level design

Wide-IP is a Fully-Qualified Domain Name (FQDN) to get the application URL, which is a web application hosted on a group of web servers, such as Apache or IIS. BIG-IP DNS resolves queries to define wide-IP FQDN association with a virtual server (VIP) from a GSLB pool that has two virtual servers at each site.

The load-balancer pool algorithms for the LTM virtual server and BIG-IP DNS virtual server are not the same, and the LTM virtual server load-balancer algorithm is chosen by the user from a drop-down field. The BIG-IP DNS GSLB pool algorithm is defined on user input. There are three kinds of GSLB pool algorithms that were chosen for the LBaaS design: global delivery, ratio, and round robin.
