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.

Pitfalls of microservices

As discussed earlier, building an application with microservices has many benefits, but it's not a silver bullet by any means.

You need to be aware of these main problems you might have to deal with when coding microservices:

  • Illogical splitting
  • More network interactions
  • Data storing and sharing
  • Compatibility issues
  • Testing

These issues will be covered in detail in the following sections.

Illogical splitting

The first issue of a microservice architecture is how it gets designed. There's no way a team can come up with the perfect microservice architecture on their first shot. Some microservices like the PDF generator are an obvious use case. But as soon as you deal with the business logic, there's a good chance that your code will move around before you get a good grasp of how to split things into the right set of microservices.

The design needs to mature with some try-and...
