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.

Summary

In this chapter, we have looked at how to centralize authentication and authorization in a microservices-based application environment using OAuth2 and JWTs. Tokens give us the ability to limit what a caller can do with one of the microservices, and for how long they can do it.

When used with public and private keys, it also limits the damage an attacker can inflict if one component of the whole application is compromised. It also ensures that each connection is cryptographically validated.

A secure code base is the first step to a secure application. You should follow good coding practices and make sure your code does not do anything bad when interacting with incoming user data and resources. While a tool like Bandit will not guarantee the safety and security of your code, it will catch the most obvious potential security issues, so there should be no hesitation about continuously running it on your code base.

Lastly, a WAF is also a good way to prevent some fraud...
