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.

Splitting a Monolith

Now that we know which components are consuming the most resources and taking the most time, how should we split them up?

It's already possible to move several components in our service to separate servers. RabbitMQ, Celery, and the database all communicate over the network, and so while there are a lot of steps to setting up new servers and configuring them, it is a well-understood process to install those hosts and update our application to use new URLs. This lets our API concentrate on handling network connections and moves the larger tasks to their own workers.

A developer must also consider setting up network security, accounts, access control and other concerns relating to running and securing a service.

The parts of our own application are trickier: we call functions to invoke our own features, and we will need to call a REST API instead. Should this be done using one large deployment and all the changes in one go? Should...
