This document discusses various cloud native concepts including microservices, container orchestration, service mesh, event-driven architecture, data integration, observability, and automation. It provides examples of how these concepts can be applied to cloud native reference architectures including event sourcing, change data capture, and distributed transactions using saga patterns and local transaction coordinators.
