Python Microservices Development

Overview of this book

We often deploy our web applications into the cloud, and our code needs to interact with many third-party services. An efficient way to build applications to do this is through microservices architecture. But, in practice, it's hard to get this right due to the complexity of all the pieces interacting with each other. This book will teach you how to overcome these issues and 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: you’ll build everything using Python 3 and its amazing tooling ecosystem. You will understand the principles of TDD and apply them. You will use Flask, Tox, and other tools to build your services using best practices. You will learn how to secure connections between services, and how to script Nginx using Lua to build web application firewall features such as rate limiting. You will also familiarize yourself with Docker’s role in microservices, and use Docker containers, CoreOS, and Amazon Web Services to deploy your services. This book will take you on a journey, ending with the creation of a complete Python application based on microservices. By the end of the book, you will be well versed with the fundamentals of building, designing, testing, and deploying your Python microservices.

Introduction

Chapter 8. Bringing It All Together

of the work done so far has focused on building microservices, and making them interact with each other. It is time to bring everything together by creating the tip of the iceberg--the User Interface (UI) through which our end users use the whole system with a browser.

Modern web applications rely a lot on client-side JavaScript (JS). Some JS frameworks go all the way to provide a full Model-View-Controller (MVC) system, which runs in the browser and manipulates the Document Object Model (DOM), which is the structured representation of the web page that's rendered in your browser.

The web development paradigm has shifted from rendering everything on the server side, to rendering everything on the client side with data collected from the server on demand. The reason is that modern web applications ;change portions of a loaded web page dynamically ;instead of calling the server for a full rendering. It is faster, requires less network bandwidth, and offers...
