Reference architectures are standardized architectures that provide a frame of reference for a vertical domain or sector. Reference models or architectures provide a common vocabulary, reusable designs, and industry best practices. They are not solution architectures (i.e., they are not implemented directly) but used rather as a constraint for more concrete architectures. Typically, a reference architecture includes common architecture principles, patterns, building blocks, and standards.
