Strategies, best practices, and patterns that will help you design resilient microservices architecture and streamline your API integrations.

In Microservice APIs, you’ll discover:

Service decomposition strategies for microservices
Documentation-driven development for APIs
Best practices for designing REST and GraphQL APIs
Documenting REST APIs with the OpenAPI specification (formerly Swagger)
Documenting GraphQL APIs using the Schema Definition Language
Building microservices APIs with Flask, FastAPI, Ariadne, and other frameworks
Service implementation patterns for loosely coupled services
Property-based testing to validate your APIs, and using automated API testing frameworks like schemathesis and Dredd
Adding authentication and authorization to your microservice APIs using OAuth and OpenID Connect (OIDC)
Deploying and operating microservices in AWS with Docker and Kubernetes

Microservice APIs teaches you practical techniques for designing robust microservices with APIs that are easy to understand, consume, and maintain. You’ll benefit from author José Haro Peralta’s years of experience experimenting with microservices architecture, dodging pitfalls and learning from mistakes he’s made. Inside you’ll find strategies for delivering successful API integrations, implementing services with clear boundaries, managing cloud deployments, and handling microservices security. Written in a framework-agnostic manner, its universal principles can easily be applied to your favorite stack and toolset.

About the technology
Clean, clear APIs are essential to the success of microservice applications. Well-designed APIs enable reliable integrations between services and help simplify maintenance, scaling, and redesigns. Th is book teaches you the patterns, protocols, and strategies you need to design, build, and deploy effective REST and GraphQL microservices APIs.

About the book
Microservice APIs gathers proven techniques for creating and building easy-to-consume APIs for microservices applications. Rich with proven advice and Python-based examples, this practical book focuses on implementation over philosophy. You’ll learn how to build robust microservice APIs, test and protect them, and deploy them to the cloud following principles and patterns that work in any language.
