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.

Building your first microservices application


We are now ready to build our first application using the microservices architecture. During the development of this application, we will get to see how we can utilize the knowledge that we have gained so far to roll out a working application.

Now, regarding our example, to keep this application simple and provide an easy understanding of how the microservices architecture works, we will build a simple to-do-list-creation application: Let's take a look at how this application will look, as stipulated in the following list:

  • The application will consist of two microservices—namely the to-do manager service and the user authentication service
  • The services will be developed in Python
  • For the purpose of this exercise, the services will utilize their own SQLite databases
  • The to-do service will depend upon the user service to gather any kind of information related to the user operations, including user authentication, profile fetching, and so on
  • The services...
