Here's a system architecture diagram. The term "architecture" refers to an abstract description of the things that make up a system. It establishes their relationships and entails a series of decision-making procedures. Architecture is both a vision and a framework. The distribution of functional correspondences is depicted in a system architecture diagram. These are formal components, the physical manifestations of ideas and data. The relationships between elements, characteristics, and the environment are defined by architecture. It's not easy to draw an architecture diagram. The examples are intended to make things simple to grasp. An architectural diagram is a representation of a system that individuals use to abstract the broad structure of a software system and construct restrictions, relationships, and boundaries between components. It gives a comprehensive perspective of the software system's physical deployment and evolution plan.
