Ps Gtm Data Center

[CodeCentral_194]

Problem this snippet solves:

The components that make up the BIG-IP Global Traffic Manager can be divided into two categories: logical and physical components. Logical Components are abstractions of network resources, such as virtual servers. Physical components, on the other hand, have a direct correlation with one or more physical entities on the network. In this article, I will discuss Data Centers (one of the physical network components in the Global Traffic Manager) and illustrate how to programmatically manage them with the iControl API.
