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.

Building our first serverless application


With our basic knowledge of the serverless architecture and how it works, it's now time for us to develop our first serverless application. For this tutorial, we are going to use the Apache OpenWhisk project, which will help us run our demo application on our local development system. So, let's take a look at what Apache OpenWhisk has to offer us and how we can utilize the platform for our benefit.

A quick introduction to Apache OpenWhisk

The Apache OpenWhisk platform provides us with the features and functionality that allow us to set up our own platform for running serverless applications. The project provides the functionality for executing functions based on the triggering of certain events in the environment.

The execution of these functions happens inside the docker containers, and the OpenWhisk platform manages the deployment and scaling of these functions inside it.

Here are some of the features provided by the platform:

  • Easy-to-use tools: The...
