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.

Chapter 2: APIs as Digital Connectors

APIs offer the ability to access information exposed by any system directly using a simple request-response mechanism without the need for a user interface (UI). As they allow you to connect to a system, in a way similar to the plug and play model, they can be seen as digital connectors.

The Connector pattern is used in software engineering to enable network connectivity between communication endpoints, such as the client and the server. It is used in conjunction with the Acceptor pattern to enable network devices to evolve independently of the mechanisms that passively establish connections used by the services:

APIs are the modern world manifestation of the foundational blocks for these frontline connectivity touchpoints. Hence, it is important to treat APIs as digital assets of enterprise innovation,...
