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.

A good option is a tool like Circus (http://circus.readthedocs.io), which can run any kind of process, even when they are not ASGI or WSGI applications. It also has the ability to bind sockets and make them available for the managed processes. In other words, Circus can run a Quart app with several processes, and can also manage some other processes if needed.

Circus is a Python application, so, to use it, you can simply run the command pip install circus. Once Circus is installed, it provides a few commands—through the entry_points method described earlier. The two principal commands are circusd, which...
