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.

Summary

In this chapter, we looked at what software architecture is and when it is required, as well as its focus on the long-term approach, which is characteristic of the discipline. We learned that the underlying structure of software is difficult to change and that that aspect should be taken into consideration when designing and changing a software system.

We described how the most important thing is to divide a complex system into smaller parts and assign clear goals and objectives to each of them, keeping in mind that these smaller parts can use multiple programming languages and refer to different scopes. We also described the LAMP architecture and how it's a widely successful starting point when creating simple web service systems.

We talked about how Conway's Law affects the architecture of a system, as underlying team structures have a direct impact on the implementation and structure of software. After all, software is operated and developed by humans, and human communication needs to be accounted for to implement it successfully.

We described the example that we will use throughout the book to describe the different elements and patterns we will present. Finally, we commented on the security aspects of software architecture and how creating barriers to accessing data as part of the structural design of a system can mitigate security issues.

In the next section of the book, we will talk about the different aspects of designing a system.
