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.

X.509 certificate-based authentication

The X.509 standard (https://datatracker.ietf.org/doc/html/rfc5280) is used to secure the web. Every website using TLS—the ones with https:// URLs—has an X.509 certificate on its web server, and uses it to verify the server's identity and set up the encryption the connection will use.

How does a client verify a server's identity when it is presented with such a certificate? Each properly issued certificate is cryptographically signed by a trusted authority. A Certificate Authority (CA) will often be the one issuing the certificate to you and will be the ultimate organization that browsers rely on to know who to trust. When the encrypted connection is being negotiated, a client will examine the certificate it's given and check who has signed it. If it is a trusted CA and the cryptographic checks are passed, then we can assume the certificate represents who it claims to. Sometimes the signer is an intermediary, so...
