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.

API monetization models

There are various options when it comes to monetizing your APIs. Enterprises may choose one or more options, depending on their business strategy.

The most widely used monetization options are depicted in the following image:

Figure 9.2 – API monetization models

Let's review each option in more detail.


One of the most common ways to get developers to start using your APIs is to offer a free tier. There are zero charges to be paid by the consumers while using your APIs. This model is suitable when the API made available is a low-value asset or a shared service, and you can rely on other mechanisms to generate revenue.

For example, application developers can integrate with identity providers such as Microsoft, Facebook, or Google to implement OAuth-based authentication within their apps for free. While these APIs are free to use, the providers can attract many users to register with their platform. This gives...
