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.

What is Docker?

The Docker (https://www.docker.com/) project is a container platform, which lets you run your applications in isolated environments. Using the Linux feature called cgroups (https://en.wikipedia.org/wiki/Cgroups), Docker creates isolated environments called containers that run on Linux without a VM. On macOS and Windows, installing Docker will create a lightweight VM for you to run containers in, although this is a seamless process. This means that macOS, Windows, and Linux users can all develop container-based applications without worrying about any interoperability trouble and deploy them to a Linux server where they will run natively.

Today, Docker is almost synonymous with containers, but there are other container runtimes, such as CRI-O (https://cri-o.io/), and historical projects such as rkt and CoreOS that, together with Docker, helped shape the standardized ecosystem that we have today.

Because containers do not rely on emulation when running on...
