Software Architecture with Python

By: Anand Balachandran Pillai

Overview of this book

This book starts by explaining how Python fits into an application's architecture. As you move along, you will get to grips with architecturally significant demands and how to determine them. Later, you’ll gain a complete understanding of the different architectural quality requirements for building a product that satisfies business needs, such as maintainability/reusability, testability, scalability, performance, usability, and security. You will also use various techniques such as incorporating DevOps, continuous integration, and more to make your application robust. You will discover when and when not to use object orientation in your applications, and design scalable applications. The focus is on building the business logic based on the business process documentation, and understanding which frameworks to use and when to use them. The book also covers some important patterns that should be taken into account while solving design problems, as well as those in relatively new domains such as the Cloud. By the end of this book, you will have understood the ins and outs of Python so that you can make critical design decisions that not just live up to but also surpassyour clients’ expectations.

Aspects related to Modifiability


We have already seen some aspects of modifiability in the previous chapter. Let us discuss this a bit further, and look at some of the related quality attributes that are closely related to modifiability:

  • Readability: Readability can be defined as the ease with which a program's logic can be followed and understood. Readable software is code that has been written in a specific style, following guidelines typically adopted for the programming language used, and whose logic uses the features provided by the language in a concise, clear way.

  • Modularity: Modularity means that the software system is written in well-encapsulated modules, which do very specific, well-documented functions. In other words, modular code provides programmer friendly APIs to the rest of the system. Modifiability is closely connected to Reusability.

  • Reusability: This measures the number of parts of a software system, including code, tools, designs, and others, that can be reused in other...
