The locality of a system describes both the physical and logical distances between key components of the system. In the context of infrastructure edge computing, the system we are most concerned with spans from a user located on the device edge to an application operating from an edge data centre at the infrastructure edge, a facility which itself is then connected to a regional data centre.

Locality is an important concept in system design. In many ways it is the summation of all of the previously described issues in this section; by addressing all of them, locality allows infrastructure edge computing to enable a new class of use case which generates large amounts of data and needs that data to be processed in a complex fashion in real time. This is the true driving factor of why the infrastructure edge computing model is needed; new use cases in addition to useful augmentations of existing use cases require the capabilities which it offers, and these use cases are valuable enough to make the design, deployment, and operation of infrastructure edge computing itself worthwhile.
