Explore tools and techniques to simplify inner and outer cloud native developer loops in this conference talk. Learn how to improve developer productivity through a platform engineering and polyglot approach. Discover a toolchain that provides app-level APIs for distributed app challenges using Dapr, implements consistent polyglot feature flags with OpenFeature, and enables easy local development outside Kubernetes clusters using Testcontainers. Gain insights into creating a seamless transition from development to production environments, addressing the differences between app-centric development setups and deployment-focused production environments. Walk away with practical knowledge from a working demo showcasing an effective and lightweight approach to streamlining both inner and outer development loops in cloud native applications.
