Hands-On Enterprise Application Development with Python

By: Saurabh Badhwar

Overview of this book

Dynamically typed languages like Python are continuously improving. With the addition of exciting new features and a wide selection of modern libraries and frameworks, Python has emerged as an ideal language for developing enterprise applications. Hands-On Enterprise Application Development with Python will show you how to build effective applications that are stable, secure, and easily scalable. The book is a detailed guide to building an end-to-end enterprise-grade application in Python. You will learn how to effectively implement Python features and design patterns that will positively impact your application lifecycle. The book also covers advanced concurrency techniques that will help you build a RESTful application with an optimized frontend. Given that security and stability are the foundation for an enterprise application, you’ll be trained on effective testing, performance analysis, and security practices, and understand how to embed them in your codebase during the initial phase. You’ll also be guided in how to move on from a monolithic architecture to one that is service oriented, leveraging microservices and serverless deployment techniques. By the end of the book, you will have become proficient at building efficient enterprise applications in Python.

Chapter 2. Design Patterns – Making a Choice

When a software application development project is taken up, it is essentially thought of as a problem that requires a solution. When we start to develop the application, we start developing a solution specific to the given problem. Eventually, this solution may start getting reused in problems of a similar kind, and becomes a standard solution for solving such problems. As time passes, we see that a lot of problems that display the same pattern. Once we modify our standard solution to work on this observed pattern, we come up with a design pattern. Design patterns are no joke; they take years to produce, after being tried and tested for solving a great number of problems with a similar pattern.

The design patterns not only define the way in which we architect our software application, they also provide knowledge about what worked and what did not, while trying to solve a particular type of problem. There are times when no particular design pattern...
