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.

Patterns in EAI


EAI is an approach that has several patterns associated with it that govern how the applications are integrated. Which pattern to use usually depends upon the type of applications that are present in the enterprise infrastructure, and what kind of challenges there are in the integration.

So, let's take a look at these patterns and see how they are usually implemented.

Integration patterns

During the EAI, the integration patterns define how the applications will be integrated with each other. This may define how the different applications will communicate with each other and how these applications will transform the data. So, let's take a look at two broad ways in which the applications are integrated with each other.

Mediation pattern

In the mediation pattern of EAI, there's a central component that is responsible for the propagation of the events. For example, in the broker-based middleware model, whenever one of the applications generates an event, the event is handled by the...
