Layers in ArchiMate Core Framework
A layered view provides a natural way to look at service-oriented models. The higher layers use services that are provided by the lower layers. ArchiMate distinguishes three main layers:
The Business layer offers products and services to external customers, which are realized in the organization by business processes performed by business actors and roles.
The Application layer supports the business layer with application services which are realized by (software) application components.
The Technology layer offers infrastructural services (e.g., processing, storage and communication services) needed to run applications, realized by computer and communication hardware and system software
The most important concepts of ArchiMate are shown below. You can clearly see the uniform approach across layers.
