BIAN: estructurando el negocio bancario y su encaje con DDD y microservicios

BIAN (Banking Industry Architecture Network) is a collaborative initiative by banks and technology providers that defines a standardized reference architecture for the banking industry, decomposing banking business into well-defined functional capabilities structured as services. Its Service Landscape organizes processes into Business Areas, Business Domains, and Service Domains, naturally aligning with Domain-Driven Design (DDD) and microservices architectures by providing clear functional boundaries, autonomy, and explicit contracts between domains.
