This document discusses journeys to cloud native architectures and provides principles for success. It begins with an overview of the cloud native dream from a business perspective, aiming for faster time to market and scalability. However, common issues that can arise include tackling too much too quickly, relying on a surface-level understanding, using ineffective tools and processes, and not anticipating failure. The document concludes with principles for a successful cloud native journey: don't take on too much too quickly, acquire sufficient expertise, choose tools wisely, engage security, and plan for failure through active testing of sad paths.
