Architecture as code

This episode explores the concept of "architecture as code," focusing on bridging the gap between architectural intent and software implementation. Against the backdrop of a previous episode discussing the intersection of architecture and implementation, this episode delves into practical applications and value delivery. More significantly, the hosts introduce the idea of a lightweight architecture definition language (ADL) – a pseudocode for defining architectural constraints and generating platform-agnostic fitness functions. For instance, the ADL can define components and services, allowing tools to automatically generate tests ensuring adherence to defined rules. The discussion contrasts this approach with model-driven architecture (MDA), highlighting the ADL's agility and focus on high-value architectural constraints rather than comprehensive code generation. As the discussion pivoted to practical examples, the hosts illustrated how ADL can address issues like accidental coupling in monorepos or rampant copy-pasting in repo-per-service architectures. Ultimately, this approach aims to automate architectural validation, enabling faster feedback and improved alignment between architectural design and implementation, impacting software development workflows and potentially reshaping enterprise architecture practices.
