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.

Developer documentation

So far, we've looked at the different kinds of tests a microservice can have, and we've mentioned that the documentation should evolve with the code. We are talking here about developer documentation. This includes everything a developer should know about your microservices project, most notably:

  • How it is designed.
  • How to install it.
  • How to run the tests.
  • What are the exposed APIs and what data moves in and out?

People go to documentation to get their questions answered. There are Who, What, Where, When, Why, and How questions, such as:

  • Who should use this software?
  • What does this software do?
  • Where can it be deployed?
  • When is using it helpful?
  • Why does it work this way?
  • How do I install and configure it?

Good documentation describes why decisions were made so that people—including yourself—returning to the code can decide whether a decision made...
