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.

Is Python secure?


Python is a very readable language with simple syntax, and typically, one clearly stated way to do things. It comes with a set of well-tested and compact standard library modules. All of this seems to indicate that Python should be a very secure language.

But is it so?

Let us look at a few examples in Python, and try to analyze the security aspect of Python and its standard libraries.

For the purposes of usefulness, we will demonstrate the code examples shown in this section using both Python 2.x and Python 3.x versions. This is because a number of security vulnerabilities that are present in Python 2.x versions are fixed in the recent 3.x versions. However, since many Python developers are still using some form or the other of Python 2.x, the code examples would be useful to them, and also illustrate the importance of migrating to Python 3.x.

All examples are executed on a machine running the Linux (Ubuntu 16.0), x86_64 architecture:
