Overview of this book

FastAPI is an Asynchronous Server Gateway Interface (ASGI)-based framework that can help build modern, manageable, and fast microservices. Because of its asynchronous core platform, this ASGI-based framework provides the best option when it comes to performance, reliability, and scalability over the WSGI-based Django and Flask. When working with Python, Flask, and Django microservices, you’ll be able to put your knowledge to work with this practical guide to building seamlessly manageable and fast microservices. You’ll begin by understanding the background of FastAPI and learning how to install, configure, and use FastAPI to decompose business units. You’ll explore a unique and asynchronous REST API framework that can provide a better option when it comes to building microservices. After that, this book will guide you on how to apply and translate microservices design patterns in building various microservices applications and RESTful APIs using the FastAPI framework. By the end of this microservices book, you’ll be able to understand, build, deploy, test, and experiment with microservices and their components using the FastAPI framework.

Summary

Securing any applications is always the main priority in producing quality software. We always choose frameworks that support reliable and credible security solutions, and that can at least prevent malicious attacks from the outside environment. Although we know for a fact that a perfect security model is a myth, we always develop security solutions that can cope with the threats we know.

FastAPI is one of the API frameworks that has built-in support for many popular authentication processes, from Basic to the OpenID Connect specification. It fully supports all effective OAuth2 authentication schemes and is even open to further customization of its security APIs.

Although it has no direct support for the OpenID Connect specification, it can still integrate seamlessly with different popular identities and user management systems, such as Auth0, Okta, and Keycloak. This framework may still surprise us with many security utilities and classes in the future that we can...
