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.

Using OpenAPI

The OpenAPI Specification (https://www.openapis.org/), previously known as Swagger, is a standard way of describing a set of HTTP endpoints, how they are used, and the structure of the data that is sent and received. By describing an API using a JSON or YAML file, it allows the intent to become machine-readable—this means that with an OpenAPI Specification, you can use a code generator to produce a client library in a language of your choosing, or to automatically validate data as it enters or leaves the system.

OpenAPI has the same goal that WSDL (https://www.w3.org/TR/2001/NOTE-wsdl-20010315) had back in the XML web services era, but it's much lighter and straight to the point.

The following example is a minimal OpenAPI description file that defines one single /apis/users_ids endpoint and supports the GET method to retrieve the list of user IDs:
