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.

User stories

Firstly, what should our application do? A good way to describe our goals is by covering the desired behavior in different scenarios. If you've been involved in Agile development before, this will be familiar in the guise of "user stories." User stories are very simple descriptions of all the interactions a user can have with an application, and is often the first high-level document that is written when a project starts, as some of the stories appear in the justification or proposal for the work to begin.

Attempting to fill lots of detail early on can also make life harder; start with high-level stories and add detail as they are revisited. Sometimes a user story might be discarded if it's not feasible—it depends very much on how the work progresses and on the feasibility of each idea. User stories are also helpful to detect when it's worth splitting a feature into its microservice: a story that stands on its own could be a good...
