This document discusses why cloud native computing matters and provides three case studies. It begins by explaining how infrastructure is changing with the rise of containerization solutions in the 2010s. It then discusses why people use cloud native technologies because they work well and have a great community behind them. Three case studies are presented where companies moved workloads to cloud native solutions on Kubernetes to increase agility, reduce costs, and improve developer productivity. The document concludes by noting that while technology challenges can be solved, changing organizational culture can be the hardest challenge to address.
