10 Building Blocks , Architecture Patterns,and Design PatternsTo explain where Building Blocks fit among other Architecture concepts, in thissection we define the terms IT Architecture framework, Building Blocks , architecturepatterns, and design patterns in the context of IT Infrastructure Architecture framework refers to a concept and organizing principle thataddresses and aligns technologies prevalent in application development, applicationmiddleware, management tools, networking, computing, and storage. Theframework includes common architectures in each one of these areas and shows thesynergies between these Blocks extend the concept of a framework to architect an IT environment.
