Light Reading's Mitch Wagner and Phil Harvey discuss the recently reported deal between AT&T and Mirantis. A week ago, Mirantis announced that it was joining Airship , an open source infrastructure project that aims to help telcos use on-premises Kubernetes infrastructure to support their efforts to modernize, cloudify and otherwise make their networks more efficient (and less dependent on a single vendor). We discuss Wagner's reporting on the subject and how it led to an even bigger story about AT&T's use of OpenStack and Kubernetes and what those technology choices say about AT&T's evolving 4G network (the one that it calls \"5G\"). Wagner talks about the strategic importance of open source to AT&T and, during the last 7 minutes of the podcast, he even gives public relations pros some useful advice on getting his -- or any other editor's -- attention. At the 30-minute mark, Phil's cat Rosie decides she's not going to wait for theme music before bringing the whole show to a screeching halt, as only a professional office cat can.
