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.

Monolithic design

This section presents extracts from the source code of the monolithic version of Jeeves. If you want to study it in detail, then the whole application can be found at https://github.com/PacktPublishing/Python-Microservices-Development-2nd-Edition/tree/main/monolith.

The first thing to consider is the retrieval of data from Slack into our application. There will be a single endpoint for this, as Slack sends all its events to the URL that the application developer configures. Later on, we can also add other endpoints to work with other environments, such as IRC, Microsoft Teams, or Discord.

We will also need a small interface to allow people to adjust the settings outside Slack, as controlling third-party authentication tokens and updating permissions for those tools is much easier using a web page. We will also need a small database to store all this information, along with other settings that we want our microservice to have.

Lastly, we will need some...
