Point of delivery (networking)

From Wikipedia, the free encyclopedia

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." [1]

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,[2] 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 deployable module which delivers a service.

The POD design pattern is especially important in service provider infrastructure, for instance in datacenters supporting cloud computing services, in order to sustain scalability as usage grows.
