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 microservices

In this book, we will use Flask as a web framework to build our microservices. Flask is a powerful web framework, which is easy to learn and simple to use. Additionally, in Flask, we need a little boilerplate code to get a simple app up and running.

Since we will create our application using the twelve-factor app concept, we will begin by ensuring that we have a centralized code base. By now, you should know how to create a GitHub repository. If not, make sure you create it as per the blogpost link provided in Chapter 1, Introducing Cloud Native Architecture and Microservices. We will be pushing the code regularly to the repository.

Assuming you have created the repository during the course of this book, we will use the GitHub repository (https://github.com/PacktPublishing/Cloud-Native-Python.git).

So, let's set up our local directory in sync with the...
