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.

API gateways in microservices


When building a microservices architecture, we have a lot of choices, and we are mostly free to choose a technology stack that is best suited for implementing a microservice. Along with this, we always have an option to render different features for different devices by rolling out a different microservice that is specific to them. But when we do this, we also add complexity to the client, which now has to handle all these different scenarios.

So, let's first take a look at the challenges we may face on the client side, as shown in the following diagram:

The preceding diagram shows the challenges that we face, as shown in the following list:

  • Handling different APIs: When every device has a specific microservice that provides the set of features that it requires, the client for that device needs to know about the API endpoints related to that specific service. This adds complexity because now the team that is responsible for handling the development of the clients...
