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.

Besides the static HTML content, the website has a booking feature that will let its users book hotels in any city in the world. Users can search for hotels, then book them with their credit cards.

When a user performs a search on the hotel website, the application goes through the following steps:

  1. It runs a couple of SQL queries against its hotel database.
  2. An HTTP request is made to a partner's service to add more hotels to the list.
  3. Results are sent to the JavaScript embedded in the web page, to render the information for the viewer.

From there, once the user has found the perfect hotel and selected the booking option, the application performs these steps:
