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.

Microservices and the changing EAI landscape


Recently, organizations have started to move toward a new approach for the development of their applications. This approach focuses on the development of the application when composed of several small services that are good at providing a single functionality and providing it well. These small services are known as microservices.

These microservices model the functionality of a subset of an enterprise domain. For example, there could be a service in the infrastructure that is responsible for handling the user credential and authentication, another service that could be handling the functionality of emails, and yet another service that processes the paychecks of the employees.

All of these services communicate over the network by the mechanism of passing messages or through making API calls from one service to another service through the use of APIs exposed by the service so as to achieve a particular use case.

Now, in contrast to traditional applications...
