I get asked to talk on DevOps a lot. Here’s my current (late 2016 and 2017) presentation, going over the why’s, the how’s, the technologies, and the meatware that supports including some best and worst practices based on what Pivotal customers do. See the newer slides with big pictures on most slides, and some of the older slides
Also, here’s a more blatantly pro-Pivotal (and longer) version that you might have seen, esp. if the talk title was something like “Digital Transformation in the Streets.”
Much of it draws a lot on my cloud native journey booklets as well.
