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.

Summary


This chapter was about deploying your Python code to production. We looked at the different factors that affect the deployability of a system. We went on to discuss the tiers in deployment architecture, such as the traditional four-tiered and the three- and two- tiered architectures including combinations of development, testing, staging/QA, and production tiers.

We then went on to discuss the details of packaging Python code. We discussed the tools of pip and virtualenv in detail. We looked at how pip and virtualenv can work together, and how to install a set of requirements using pip, and set up similar virtual environments using it. We also took a quick look at relocatable virtual environments.

We then went to discuss PyPI—the Python Package Index which hosts Python third-party packages on the web. We then went through a detailed example of setting up a Python package using setuptools and the setup.py file. We used the mandelbrot application as an example in this case.

We ended that...
