The Changing Role of IT

Many large enterprises are feeling pressure from the rapid digitalization of the world: digital disruptors attack unexpectedly with brand-new business models; the "FaceBook generation" has dramatically different user expectations; and a whole slew of new technologies has become available to everyone with a credit card. This is tough stuff for enterprises that have been, and still are, very successful, but are built around traditional technology and organizational structures. "Turning the tanker", as the need to transform is often described, has become a board room-level topic in many traditional enterprises. Not as easily done as said.

The Changing Role of Architects

Chief IT Architects and CTOs play a key role in such a digital transformation endeavor. They combine the technical, communication, and organizational skill to understand how a tech stack refresh can actually benefit the business, what "being agile" and "DevOps" really mean, and what technology infrastructure is needed to assure quality while moving faster. Their job is not an easy one, though: they must maneuver in an organization where IT is often still seen as a cost center, where operations means "run" as opposed to "change", and where middle-aged middle-management has become cozy neither understanding the business strategy nor the underlying technology. It's no surprise then that IT architects have become some of the most sought-after IT professionals around the globe.

What You Will Learn

This book supports IT architects with the skills necessary to become effective not just in systems architecture, but also in shaping and driving the necessary transformation of large-scale IT departments. In today’s world, technical and organizational transformation have become inseparable. Organized into 37 episodes, this book explains:

• The role and qualities of an architect in a large enterprise
• Architecture at enterprise scale
• Communicating to a variety of stakeholders
• Understanding organizational structures and systems
• Transforming traditional organizations

"A sound strategy is the difference between making a wish and making it come true. Stop having cloud wishes and define a cloud strategy."

Cloud computing is an amazing resource that can provide fully managed platforms, auto-optimizing and even auto-healing operations, per-second billing, pre-trained machine learning models, and globally distributed transactional data stores. So, it's no wonder that most enterprises are engaging in a cloud migration or cloud transformation, as it's often called. . 

Migrating a whole enterprise to the cloud isn't as easy as pushing a button. Simply lifting and shifting legacy applications to the cloud is unlikely to bring the anticipated benefits whereas re-architecting applications to run optimally in the cloud is likely to be cost prohibitive and not a worthwhile investment. So, enterprises need to have a better and more nuanced strategy than just "cloud first!"

A Decision-based Approach to Cloud Strategy

A sound cloud strategy isn't something you can copy-paste from a recipe book or from another organization. Each organization has a different starting point and works under different constraints and objectives. In addition, a cloud strategy doesn't just deal with technical change but also requires close alignment between business and IT goals.

Unfortunately, most books on cloud computing either stay at a very high level or describe specific vendors and products. This book fills this gap by taking a fresh look at cloud computing and providing decision models to lay out a nuanced migration journey.
