Cloud Strategy
Cloud Strategy
A Decision-Based Approach to Successful Cloud Migration
About the Book
Most books on cloud computing want to tell you that you should become “digital” or ”agile”, or dwell on product details that are prone to be outdated by the time you read them. This book fills the giant gap in between. It’ll help you ask the right questions to define a strategy based on meaningful decisions. It’ll also help you unravel existing assumptions to realize the full potential of the new technology. And it demystifies modern technology without dumbing it down.
The book condenses my experience developing and implementing cloud strategies for large organizations into an easy-to-read but insightful format that covers IT strategy, architecture, financials, and organizational changes.
A Decision-based Approach to Cloud Strategy
You can’t copy-paste a strategy from a recipe book or from another organization. Diverse starting points, objectives, and constraints imply different choices and trade-offs. Also, a cloud strategy must include close alignment across business, organization, and technology. This book questions existing assumptions ("Why run software you didn't build?") and presents technology-neutral decision models ("8 ways to slice the hybrid cloud") ideally suited to defining and communicating a well-thought-out migration journey.

Contents
Based on the author's extensive experience taking large organizations to the cloud, 33 Chapters highlight options, decisions, and trade-offs - the core elements of any strategy. These mental models come to life through real-life anecdotes and examples:
- Understanding the Cloud - Cloud is not a mere technology upgrade.
- Organizing for the Cloud - To get the most out of the cloud, you’ll turn your organization sideways.
- Moving to the Cloud - Many roads lead to Rome, but some go faster than others. Choose wisely.
- Architecting the Cloud - Multi, hybrid, portable, multi-tenant, and disposable? Stay clear of buzzwords and embrace rational decision models.
- Building for the Cloud - Cloud applications are more than containers and serverless. Also, IaC is a misnomer.
- Budgeting the Cloud - Cloud can significantly reduce your operational costs—if you leave existing assumptions behind.
This book will be your trusted advisor for your cloud journey. It applies the mindset of “The Software Architect Elevator” (my prior book) to cloud computing.

Reader Testimonials

This is great book (as I've come to expect from Gregor Hohpe!). The author has a way of transforming tons of experience and complexity into practical and useful decision models. It certainly gave me several different lenses through which to analyze the cloud.

I wish this book existed 2 years ago. My personal experience in enterprise cloud adoption resonates much with various sections in this book. Deliberately maintaining a cloud service provider neutral narrative, much arguments, metaphors, examples, do’s and don’s in the book sound unusually convincing as they reflect the reality I observe on the ground. A much needed guidance for those genuinely look for sustainable value realization from cloud.
