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.

Understanding the execution of application Inside Openwhisk


With the demo application in place, it's time for us to understand how the execution of this application works behind the scenes.

Behind the successful execution of the application, there are several steps involved which start from the wsk action invoke command that we ran to execute our application. So, let's take a look at the steps that happened behind the scenes:

  1. Making the API call: Every action that we build to deploy on OpenWhisk is mapped as an API endpoint that will invoke the action. When we run wsk action invoke, the command makes a call to the API endpoint that has been mapped for the provided function. This call is then intercepted by Nginx inside OpenWhisk, which acts as a termination point for SSL and then invokes the controller.
  2. Processing by the controller: The controller, which is an implementation of the REST API, disambiguates what the request is supposed to do based on the HTTP method used for the request. Once...
