Advantages of a Layered Architecture

Conventional programming can sometimes make our code difficult to understand. This is why professionals are increasingly moving toward layered architecture. Before delving deeper into the details of clean architecture, let’s first discuss the advantages of layered architecture.

Loosely coupled

The stages of the layered architecture are separated, and there is a great deal of data transformation between these stages. One way we can achieve independence—or loose coupling—between the components of a computer system is through the use of common data formats.

To better understand what loose coupling means for a programmer, let’s consider the last picturepicture we saw in the previous section. What changes if the web framework was instead a command-line interface (CLI)?
