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.

Deploying on AWS

In the previous chapters, we ran our different microservices directly in the host operating system, as it is sometimes the quickest way to get started, while also being a useful approach in general—especially for smaller installations or development where everything can be contained in a virtual environment. However, if the application requires a database or a compiled extension, then things start to be tightly coupled to the operating system and version. Other developers with slightly different systems will start to run into problems, and the more differences between a development environment and a production one, the more trouble you will have when releasing your software.

Virtual Machines (VMs) can be a good solution, as they provide an isolated environment in which to run your code. A VM is essentially a piece of software pretending to be a real computer, in which there is a real operating system running in the pretend computer. If you've ever...
