Shadow, Rogue, and Zombie APIs

The organizational and technical roots of sprawl I have covered so far create gaps–seams in the estate where interfaces exist but oversight does not. In this fourth post of the series I want to name the specific creatures that live in those gaps, because “API sprawl” is an abstract phrase and these things are not abstract at all. They are running in your production environment right now, and the reason they are dangerous is precisely that no one is looking at them.
