Software architecture design, when performed in context of agile software development (ASD), sometimes referred to as “agile architecting,” promotes the emerging and incremental design of the architectural artifact in a sense of avoiding “big design upfront” (BDUF). This chapter presents the Agile Modeling Process for Logical Architectures (AMPLA) method, an approach for supporting the emergence of a candidate (logical) architecture, rather than BDUF, the architecture in an early phase. The architecture then emerges throughout agile iterations, where AMPLA plays a key contribution for providing traceability between models, from the business need to service specifications, ranging from design stages to deployment, hence covering a software development life cycle (SDLC).
