From Zero to Application Delivery with NixOS - Philly ETE 2016

Explore a comprehensive approach to managing configurations and infrastructure in microservice architectures through this conference talk. Learn how to overcome operational challenges in CI/CD environments and production deployments using immutable infrastructure principles and a powerful toolchain. Discover techniques for defining infrastructure as code alongside application code, enabling repeatable configurations, ephemeral testing environments, consistent CI/CD setups, and transparent dependency management. Gain insights into the Nix ecosystem and its benefits for achieving reliable software delivery, including repeatable development environments, consistent CI dependencies, diffable dependencies, predictable deployments, and improved security auditing. Understand the tradeoffs and advantages of this approach, and get guidance on next steps for implementing these practices in your own projects.
