Software architecture is a critical aspect of software development. It involves the high-level structuring of software systems to meet technical and business requirements. Software architects play a pivotal role in this process by making design choices, dictating technical standards, and leading implementation efforts.
This paper proposes a description of different architecture types. However, as this has been done many times before, I want to add the perspective of the C4 model to help understand who will intervene and at each level and with whom they will have to interact.
