A monolithic architecture is one in which a software application is designed to work as a single, self-contained unit. Applications that have this type of architecture are common. The components within a monolithic architecture are interconnected and interdependent, resulting in tightly coupled code.
The following diagram shows an application with a monolithic architecture:
The different concerns of an application, such as user interface, business logic, authorization, logging, and database access, are not kept separate in a monolithic architecture. These different pieces of functionality are intertwined in a monolithic application.
