I think software architecture is the wrong word for this. It’s module structure, architecture to me includes all the surrounding bits concerning the “ilities”. (Availability, Interoperability, Modifiability, Usability, Testability, Security, Performance). I say this because getting the module structure right is important but not the only factor to a successful application. My favorites in regard to the topic of module structure are David Parnas and Juval Lowy
