All of the resources on a network are associated with a data center. BIG-IP DNS(formerly GTM) consolidates the paths and metrics data collected from the servers, virtual servers, and links in the data center. BIG-IP DNS uses that data to conduct load balancing and route client requests to the best-performing resource, based on a variety of factors.

 

A server defines a physical system on the network. Servers contain the virtual servers that are the ultimate destinations of DNS name resolution requests. A virtual server is a specific IP address and port number that points to a resource on the network. In the case of host servers, this IP address and port number likely point to the resource itself.

 

Here is the following order of creation in generalization.

 

Data Center --> Servers --> Virtual Servers --> pool --> Topology (optional) ---> WideIP
