Tarek Ziade is a Python developer, located in the countryside near Dijon, France. He works at Mozilla in the services team. He founded a French Python user group called Afpy, and he has written several books about Python in French and English. When he is not hacking on his computer or hanging out with his family, he's spending time between his two passions, running and playing the trumpet.
You can visit his personal blog ( Fetchez le Python ) and follow him on Twitter (@tarek_ziade ). You can also take a look at one of his books on Amazon, Expert Python Programming , published by Packt.

William Kahn-Greene has been writing Python and building applications on the web since the late 90s. He works in the crash-stats group on the crash ingestion pipeline at Mozilla and also maintains a variety of Python libraries, including bleach . When he is waiting for CI to test his code changes, he is building things with wood, tending to his tomato plant, and cooking for four.

If we try to deploy our web applications into the cloud, it requires our code to interact with many third-party services. Using microservice architectures, you can build applications that will allow you to manage these interactions. However, this comes with its own set of challenges, since each set has its own complexity, and getting their interaction right isn't easy. This easy-to-follow guide covers techniques to help you overcome these challenges. You will learn how to best design, write, test, and deploy your microservices. The real-world examples will help Python developers create their own Python microservices using the most efficient methods. By the end of this book, you will have acquired the skills to craft applications that are built as small standard units, using all the proven best practices and avoiding the usual traps. Also, this is a useful guide for the vast community of Python developers who are shifting from monolithic design to the new microservice-based development paradigm.

, Understanding Microservices , defines what microservices are, and their roles in modern web applications. It also introduces Python and explains why it's great for building microservices.

, Discovering Flask , introduces Flask and goes through its main features. It showcases the framework with a sample web application that will be the basis for building microservices.

, Coding, Testing, and Documenting - the Virtuous Cycle , describes the Test-Driven Development and Continuous Integration approach, and how to use it in practice to build and package Flask applications.

, Designing Runnerly , takes you through the app features and user stories, explains how it could be built as a monolithic app, then decomposes it into microservices and explains how they interact with the data. It will also introduce the Open API 2.0 specification (ex-Swagger), which can be used to describe HTTP APIs.
