Cloud Native Python

By: Manish Sethi

Overview of this book

Businesses today are evolving so rapidly that having their own infrastructure to support their expansion is not feasible. As a result, they have been resorting to the elasticity of the cloud to provide a platform to build and deploy their highly scalable applications. This book will be the one stop for you to learn all about building cloud-native architectures in Python. It will begin by introducing you to cloud-native architecture and will help break it down for you. Then you’ll learn how to build microservices in Python using REST APIs in an event driven approach and you will build the web layer. Next, you’ll learn about Interacting data services and building Web views with React, after which we will take a detailed look at application security and performance. Then, you’ll also learn how to Dockerize your services. And finally, you’ll learn how to deploy the application on the AWS and Azure platforms. We will end the book by discussing some concepts and techniques around troubleshooting problems that might occur with your applications after you’ve deployed them. This book will teach you how to craft applications that are built as small standard units, using all the proven best practices and avoiding the usual traps. It's a practical book: we're going to build everything using Python 3 and its amazing tooling ecosystem. The book will take you on a journey, the destination of which, is the creation of a complete Python application based on microservices over the cloud platform

Building a Web Application in Python

In the previous chapter, we focused on building our microservices, which is, basically, backend RESTful APIs, and testing it to make sure the response will be as expected. So far, we have been testing these RESTful APIs using curl, or maybe, using a testing framework, that is, nose, unittest2, and so on. In this chapter, we will create some HTML pages and write a JavaScript REST client, which will interact with microservices.

The topics that we will cover in this chapter are as follows:

  • Building HTML pages and data binding
  • JavaScript REST client using knockout.js

In this chapter, we will create a client application which will need to create dynamic content that is gathered from an HTML web page and, based on the actions of the user, will update the content as a response on the backend service.
