Python Architecture Patterns

By: Jaime Buelta

Overview of this book

Developing large-scale systems that continuously grow in scale and complexity requires a thorough understanding of how software projects should be implemented. Software developers, architects, and technical management teams rely on high-level software design patterns such as microservices architecture, event-driven architecture, and the strategic patterns prescribed by domain-driven design (DDD) to make their work easier. This book covers these proven architecture design patterns with a forward-looking approach to help Python developers manage application complexity—and get the most value out of their test suites. Starting with the initial stages of design, you will learn about the main blocks and mental flow to use at the start of a project. The book covers various architectural patterns like microservices, web services, and event-driven structures and how to choose the one best suited to your project. Establishing a foundation of required concepts, you will progress into development, debugging, and testing to produce high-quality code that is ready for deployment. You will learn about ongoing operations on how to continue the task after the system is deployed to end users, as the software development lifecycle is never finished. By the end of this Python book, you will have developed "architectural thinking": a different way of approaching software design, including making changes to ongoing systems.

Introduction to Software Architecture

The objective of this chapter is to present an introduction to what software architecture is and where it's useful. We will look at some of the basic techniques used when defining the architecture of a system and a baseline example of the web services architecture.

This chapter includes a discussion of the implications that software structure has for team structure and communication. As the successful building of any non-tiny piece of software depends heavily on successful communication and collaboration between one or more teams of multiple developers, this factor should be taken into consideration. Also, the structure of the software can have a profound effect on how different elements are accessed, so how software is structured has ramifications for security.

Also, in this chapter, there will be a brief introduction to the architecture of an example system that we will be using to present the different patterns and discussions throughout the rest of the book.

In this chapter, we'll cover the following topics:

  • Defining the structure of a system
  • Dividing into smaller units
  • Conway's Law in software architecture
  • General overview of the example
  • Security aspects of software architecture

Let's dive in.
