Introduction A funny thing happened on the way to the data center. A technology with roots all the way back to the 1970s emerged as a "new" way to handle application develop- ment, one that could help address some of the resource ineffi- ciency problems inherent with virtualization and with legacy IT. Called containers, this currently reemerging technology construct is gaining traction and attention across the enterprise IT market- place and is the subject of this book. About This Book This 48-page journey helps you understand how Docker contain- ers and HPE can help your organization transform its IT opera- tions and save time and money in the process. You discover how containers impact IT and the business and how easy — and how challenging — containers can be. Foolish Assumptions For this book, I assume that you have at least a basic under- standing of data center computing and virtualization. The gen- eral audience for this book is anyone in IT who may want to learn more about data center architectures. You may be part of your organization's technical staff, or you may be managerial or exec- utive staff. Either way, this book is for you! Icons Used in This Book Throughout this book, you find a number of icons intended to help you better understand and remember key concepts. When you see the Remember icon, put that information in your back pocket to save for later.
