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.

Implementing EAI patterns using iPaaS

EAI solutions typically target the following primary application integration patterns:

The goal of this pattern is to replicate the data changes that occur in one application to other applications that must be notified about the changes. This will ensure that all systems are updated with the latest information. For example, when a customer updates their information in, say, a CRM system, the changes are updated in billing systems or other systems that make use of customer data:

  • Data consistency integration:

This is the most common integration pattern among all EAI flows. An end-to-end business workflow execution may involve multiple systems or applications that are mutually independent, each having its own specific function. These applications will take part in the various steps of the business workflow, wherein the outputs from one system can serve...
