Realize Enterprise Architecture with AWS and SAFe

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.

Other cloud migration strategies

Some other cloud migration strategies include repurchasing, driving factors, limitations, and risks.

Do you have a legacy application that you can’t move to the cloud? Consider buying a cloud-based product. The following is a list of examples of repurchasing that can facilitate the whole process and provide guiding principles:

  • Switch from a self-managed email system to one that provides email as a service.
  • An appliance built by the Marketplace vendor replaces a self-built VPN server.
  • Use web application firewalls instead of the Marketplace offering provided by the cloud provider.

In fact, building and operating your own email system is becoming increasingly rare. If an email service is currently running internally as part of the discovery assessment, then a recommendation for a SaaS email offering is likely to be the best value.

AWS repurchasing is continuously evolving, and the number of migrations to AWS is likely...
