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.

Securing your code

Whatever we do, an application must receive data and act on it, somehow, or it will not be very useful. If a service receives data, then as soon as you expose your app to the world, it is open to numerous possible types of attack, and your code needs to be designed with this in mind.

Anything that is published to the web can be attacked, although we have the advantage that most microservices are not exposed to the public internet, which reduces the possible ways they could be exploited. The expected inputs and outputs of the system are narrower, and often better defined using specification tools, such as OpenAPI.

Attacks are not always due to hostile intent, either. If the caller has a bug or is just not calling your service correctly, the expected behavior should be to send back a 4xx response and explain to the client why the request was rejected.

The Open Web Application Security Project (OWASP) (https://www.owasp.org) is an excellent resource...
