Overview of this book

The small scope and self-contained nature of microservices make them faster, cleaner, and more scalable than code-heavy monolithic applications. However, building microservices architecture that is efficient as well as lightweight into your applications can be challenging due to the complexity of all the interacting pieces. Python Microservices Development, Second Edition will teach you how to overcome these issues and craft applications that are built as small standard units using proven best practices and avoiding common pitfalls. Through hands-on examples, this book will help you to build efficient microservices using Quart, SQLAlchemy, and other modern Python tools In this updated edition, 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. Python Microservices Development, Second Edition describes how to use containers and AWS to deploy your services. By the end of the book, you’ll have created a complete Python application based on microservices.

We assume that the dashboard only works when you are authenticated and that there are two kinds of users: first-time and returning. The following is the user story for first-time users:

As a first-time user, when I visit the dashboard, there's a "login" link. When I click on it, the dashboard redirects me to Slack to grant access to my resources. Slack then redirects me back to the dashboard, and I am connected. The dashboard then starts to fill with my data.

As described, our Quart app performs an OAuth2 conversation with Slack to authenticate users—and we know that since we are setting up a Slack bot, people should already have an account there. Connecting to Slack also means we need to...
