Python Microservices Development – 2nd edition - Second Edition

By: Simon Fraser, Tarek Ziadé

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.

The microservice approach

If we were to build the same application using microservices, we would organize the code into several separate components that run in separate processes. We have already discussed the PDF report generator, and we can examine the rest of the application and see where we could split it into different microservices, as shown in the following diagram:

Figure 1.2: A sample microservice architecture

Don't be afraid of the number of components displayed in this diagram. The internal interactions of the monolithic application are just being made visible by separate pieces. We've shifted some of the complexity and ended up with these seven standalone components:

  1. Booking UI: A frontend service that generates the web user interface, and interacts with all the other microservices.
  2. PDF reports: A very simple service that will create PDFs for receipts or any other document given a template and some data. Also known as the PDF...
