A point of delivery, or PoD, is "a module of network, compute, storage, and application components that work together to deliver networking services. The PoD is a repeatable pattern, and its components maximize the modularity, scalability, and manageability of data centers." 
The concept of a design pattern is nothing new in computer or network architecture. In particular, the modular design principle has long been applied to telephone and data networks, for instance through a repeatable node design describing the configuration of equipment housed in point of presence facilities. The term is similarly used in cable video networks, to describe the modular component that delivers video service to a subscriber. The distinction of a PoD versus other design patterns is that it is a deployablemodule which delivers a service.
