Doing Cloud is easy. Doing it right is hard. The difficulty appears to be a problem of choice, but behind every Cloud success or failure story, there's always just one reason - cost. This book offers a framework, rooted in understanding Cloud's nature, for applying that understanding to the many shapes cost takes.

About the Book

Cloud, since its inception in the early 2000s, has come a long way. As offerings converge and the initial phase of invention winds down, it’s safe to say that Cloud is becoming a commodity. Despite this, effectively practicing Cloud is still challenging, and some companies even decide to abandon the efforts.

This book is a collection of battle-tested best practices and common-sense observations. The approaches outline here put cost - and the business speed and value it enables - at the center of Cloud adoption and keep it there throughout the whole journey.

Whether you’re building a startup or working with a multinational enterprise, the end goal remains the same: a well-architected Cloud platform that enables uncompromised business agility.
