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.

When writing software, we are often not doing so in isolation, but instead to help our company or open source project achieve a goal. Relying on our intuition to tell us whether we're doing a good job is often misleading, as our instinct is affected by all the different biases humans have. Instead, we must measure – collect numbers, watch for patterns, and analyze data.

To demonstrate how well our software is doing, both to ourselves and to others, there are three levels we can think about. The first is the list of possible things we can measure, and these are known as Service-Level Indicators (SLIs). As developers, it is easy to come up with a list of technology-related SLIs, such as:

  • The API response time in milliseconds
  • A count of the different HTTP status codes
  • The number of bytes transferred in each request

However, it is vitally important to include organization-level indicators as well, such as:
