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 4: Assuring the Quality of the API Service (or Product)

All software engineering teams strive to create a quality product as an output from the weeks of planning, designing, developing, and testing cycles. This, however, is not possible unless there is a clear and common understanding of the quality goals (or attributes) of the product under development.

A product backlog in the form of architecture backlog stories must be created and prioritized in a timely fashion to accomplish the targets/metrics set for these quality attributes. Otherwise, late discovery of critical issues, and subsequent fixing at a later stage in the project lifecycle, will turn out to be very costly.

The purpose of this chapter is to understand the important quality attributes that will apply to API-centric solutions. The objective is to assess the impact of non-functional requirements on the solution design and what trade-offs are necessary to achieve a highly reliable API platform.
