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.

The traditional approach to EAI


In the early days of EAI, the applications needed to interact with each other in various formats, which may include communicating some information or exchanging data. To facilitate this exchange, the organizations came up with a hub and spoke model for EAI.

In this hub and spoke model, there's a router-based middleware component and a concept of events. Whenever there was some change in the state of one of the applications, the application used to generate an event. The other applications subscribed to the event stream they were interested in.

Now, whenever a new event was generated, the router was responsible for the delivery of the event to the interested applications handling the conversion of data from one format into another, so that the applications could communicate with each other. In this kind of approach, the router became the central point of facilitating the integration between the different applications.

The router provided a lot of features, such...
