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.

Interacting with Other Services

In the previous chapter, our monolithic application was split up into several microservices, and consequently, more network interactions between the different parts were included.

More interactions with other components can lead to complications of their own, however, such as a high volume of messages or large data sizes delaying responses, or long-running tasks taking up valuable resources. Since many of our useful tasks involve interacting with third-party services, the techniques to manage these changes are useful both inside our application and for communicating outside of it. Having the ability to loosely couple different parts of the system using some asynchronous messages is useful to prevent blockages and unwanted dependency entanglements.

In any case, the bottom line is that we need to interact with other services through the network, both synchronously and asynchronously. These interactions need to be efficient, and when...
