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.

Identifying potential microservices

For an application that is familiar to us, we might have a lot of intuition about which components are overloaded or unreliable. After all, either we wrote it, or have rewritten large parts of it, and tested it, along with making decisions about its architecture. It's also natural to have made notes about the database growing larger, or noticing that one particular function takes a long time to run during testing.

Our own intuition may lead us astray, however, and it is a good idea to let our decisions be informed by the data we collect. Developers and operations people will have specific questions that should be answered to make a decision about the future direction of a service. Product management and other business-oriented people will also have questions that need answering, which are often not specific to the technology. Questions a developer may ask include:

  • How fast are responses to HTTP requests?
  • What are the success...
