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.

Introducing MVC


Model View Controller or MVC is a well known and popular architectural pattern for building interactive applications. MVC splits the application into three components: the Model, the View, and the Controller.

Model-View-Controller (MVC) Architecture

The three components perform the following responsibilities:

  • Model: The model contains the core data and logic of the application.

  • View: The view(s) form the output of the application to the user. They display information to the user. Multiple views of the same data are possible.

  • Controller: The controller receives and processes user input such as keyboard clicks or mouse clicks/movements, and converts them into change requests for the model or the view.

Separation of concerns using these three components avoids tight coupling between the data of the application and its representation. It allows for multiple representations (views) of the same data (model), which can be computed and presented according to user input received via...
