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.

Challenges of traditional EAI in microservices


In applications that have been developed by the modern practices of developing small microservices, hosting them over the enterprise infrastructure, and then integrating them together to talk to each other, we can no longer use the traditional approaches we were familiar with during the times of running and maintaining large monolithic applications or services. Let's first take some time to understand why point-to-point integration might not work in the case of microservices.

Point-to-point integration of microservices

In the point to point integration approach for microservices, we make the microservices interact with each other directly through the APIs exposed by them. For this to happen, each microservice needs to have the knowledge about the endpoints exposed by the other service. This is perfectly fine, but what happens if the microservice has to do some operation that depends on interaction with five other microservices?

At this point, we...
