10+ Deploys Per Day: Dev and Ops Cooperation at Flickr.

Why this matters here
Allspaw and Hammond’s Velocity 2009 talk documents Flickr’s high-frequency deploy practice and Dev–Ops cooperation as a concrete response to handoff distance between build and run.

The source supplies the emergence case; the book asks what structural coupling that proximity restores.
