ok I'll bite.
imho, repeatable patterns of deployment are a great economic and
organizational simplification. imho that doesn't mean they are
identical. There may be generational differences even in what otherwise
would be cookie cutter deployments, e.g. because devices go end of sale,
new ones become available, regional vendor preference or vendor
If these are centrally organized and operated or coordinated, then the
minimum number of variants possible considering the circumstances where
variation is is desirable. It minimizes the effort and training required
to deploy and operate the system.
If I were to take CDN pops as an example.
Inter-generational variation is necessary as are accommodations for
varying scale. the system is centrally coordinated and common operating
methods are necessary if these systems are to behave a cohesive whole.
Systems where deployment is less centralized, and local autonomy is
therefore necessary as for example occurs when local contractors use
their own equipment may come to different conclusions. e.g. that the
specification of the minimum necessary common elements becomes the only
feasible approach. For example if you are an Uber driver your minim IT
requirements are something like
Uber cell phone requirements
iPhone requirements to run the Uber driver app
Must be iPhone 4S, 5, 5C, 5S, 6, 6 Plus, 6S, 6S Plus, SE, 7, or 7 Plus
running iOS 8 or later versions
For best results: Use iPhone 5 or newer
Android requirements to run the Uber driver app
Any smart phone from 2013 or newer, running Android version 4.0 or newer
For best results: The phone should run Android 5.0 or newer
