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.

Transformation of the ESB


With the advent of the microservices revolution, the Enterprise Service Bus has also seen a change, where it has now been replaced by some similar solutions, but with the advantages of far better scalability and the removal of single point of failure.

The ESB in application integration used to play the role of a central bus, which acted as an intermediary between the applications that wanted to communicate with each other. The ESB facilitated this communication by introducing common data formats and providing adapters through which the applications could talk to the ESB.

But the ESB still suffered two major drawbacks:

  • Scalability: The ESB was a heavy piece of middleware that required a specialization to work with. The scalability of the ESB was hard due to the sheer amount of resources required to scale the bus, and this was even harder when the bus had to be scaled to support applications located in different geographies.
  • Single point of failure: The ESB proved to...
