Designing API-First Enterprise Architectures on Azure

By: Subhajit Chatterjee

Overview of this book

API-centric architectures are foundational to delivering omnichannel experiences for an enterprise. With this book, developers will learn techniques to design loosely coupled, cloud-based, business-tier interfaces that can be consumed by a variety of client applications. Using real-world examples and case studies, the book helps you get to grips with the cloudbased design and implementation of reliable and resilient API-centric solutions. Starting with the evolution of enterprise applications, you'll learn how API-based integration architectures drive digital transformation. You'll then learn about the important principles and practices that apply to cloud-based API architectures and advance to exploring the different architecture styles and their implementation in Azure. This book is written from a practitioner's point of view, so you'll discover ideas and practices that have worked successfully in various customer scenarios. By the end of this book, you'll be able to architect, design, deploy, and monetize your API solutions in the Azure cloud while implementing best practices and industry standards.

OpenAPI Specification

The OpenAPI Specification (OAS) defines a standard that can be used to create the interface definition of a RESTful API in a language-agnostic manner. This allows the consumers of the API, whether they're humans or computers, to easily decipher the capabilities of the services without requiring access to source code, documentation, or even inspections of the network traffic. Owing to its wide acceptance in the community, APIs that are defined properly using the specification constructs will be readily available for use by the developers planning to integrate with the API.

There are a variety of developer productivity tools that can parse the OpenAPI definition files, as well as display the API specification in a graphical manner that is easy to understand and follow. There are tools that can generate stubs or proxy classes using these definition files or even in API testing, using mocks.
