Chapter 8. Python – Architectural Patterns

Architectural patterns are the highest level of patterns in the pantheon of patterns in software. Architectural patterns allow the architects to specify the fundamental structure of an application. The architectural pattern chosen for a given software problem governs the rest of its activities, such as the design of systems involved, communication between different parts of the system, and so on.

There are a number of architectural patterns to choose from depending upon the problem at hand. Different patterns solve different classes or families of problems, creating their own style or class of architecture. For example, a certain class of patterns solves the architecture of client/server systems, another helps to build distributed systems, and a third helps to design highly decoupled peer-to-peer systems.

In this chapter, we will discuss and focus on a few architectural patterns that are encountered often in the Python world. Our...
