Realize Enterprise Architecture with AWS and SAFe

By: Rajnish Harjika

Overview of this book

Agile implementation of enterprise architecture (EA) in the cloud is a powerful organizational tool, but it is challenging, particularly for architects who are used to on-premises environments. This in-depth guide will tell you all you need to know to reap the benefits of applying EA in your organization to achieve operational efficiency. Starting with an overview of the foundations of enterprise architecture, you'll see how it can be applied to AWS as well as explore the frameworks AWS provides for EA, such as the AWS Well-Architected Framework. That's not all – the book shows you how these frameworks align with The Open Group Architecture Framework (TOGAF) architecture development method (ADM) and the Zachman Framework so that you can choose the right fit for your organization. As you advance, you'll learn how to apply SAFe to make your organization agile as well as efficient. Once you've gotten to grips with the theory, you can explore use cases and take a quiz at the end of the book to test yourself and see how EA is applied in practice. By the end of this enterprise architecture book, you'll have the skills and knowledge required to apply EA in the cloud with AWS and drive your organization to become super-efficient and agile.

Phases of the architecture development method

As TOGAF is mostly used by VLEs, an ADM will suffice for smaller firms. Iteration during requirements phases is common in agile projects. In most cases, business requirements are elicited and clarified beforehand without you having to define them and understand them clearly. ADM has 10 phases, as outlined here. The TOGAF documentation on Open Group’s website provides a complete overview of TOGAF’s approach and descriptions of each phase, identifying its objectives, inputs, steps, and outcomes.

Preliminary phase – framework and principles

An organization’s preliminary phase is concerned with defining where, what, why, who, and how the architecture is done within that particular enterprise. It addresses the enterprise definition and helps you identify key drivers and elements. It also allows you to determine the requirements for the architecture and define the architectural principles that will perform any...
