Understanding Architecture as Code

Architecture is deeply intertwined with implementation, focusing on how architectural intent translates into real systems and software. A key concept introduced is architecture as code, which emphasizes the necessity of creating concrete expressions of architectural characteristics through scripting and automated checks. The idea posits that architecture is often perceived abstractly, limiting the ability to assess trade-offs and actual execution while also suggesting that traditional unit tests are not sufficient for architectural validation. By leveraging fitness functions, architectural qualities can be monitored and verified through lightweight scripts that assess adherence to intended designs.
