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 packaging toolchain

Python has come a long way since the days of those early packaging methods. Numerous Python Enhancement Proposals (PEPs) were written to improve how to install, release, and distribute Python projects.

Distutils had some flaws that made it a little tedious to release software. The biggest pain points were its lack of dependency management and the way it handled compilation and binary releases. For everything related to compiling, what worked well in the nineties started to get old-fashioned ten years later. No one in the core team made the library evolve due to lack of interest, and also because Distutils was good enough to compile Python and most projects. People who needed advanced toolchains used other tools, like SCons (http://scons.org/).

In any case, improving the toolchain was not an easy task because of the existing legacy system based on Distutils. Starting a new packaging system from scratch was quite hard, since Distutils was part of...
