IntroductionOver the past decade, a lot has happened to IT and to thetechnology industry. First and foremost, business leaderscontinue to demand more from their IT functions, including better and faster service, with seemingly endless expectationsfor increased efficiency.In addition, several industry trends have had significant effectson enterprise IT:»» The proliferation of purpose-built devices»» The rise of software-defined infrastructure (SDI)»» The emergence of cloud computing — or at least cloudprinciples and economics — as a key driver of enterprise IT»» The emergence of converged infrastructure»» The use of flash storage in certain enterprise applications»» The increased prevalence of software-defined networkingAt the center of all these trends lies hyperconverged infrastructure, which is the next generation of a series of converged opportunities that have hit the market. Hyperconverged infrastructureis a data center architecture that embraces cloud principles andeconomics and a software-first architecture. Hyperconvergedinfrastructure consolidates server compute, storage, hypervisor,data protection, data efficiency, global management, softwaredefined networking, and other enterprise functionality on commodity x86 building blocks to simplify IT, increase efficiency,enable seamless scalability, improve agility, and reduce costs.About This BookThe hyperconvergence story has many chapters. In this book,I discuss the trends that are leading modern IT to hyperconvergedinfrastructure. I also discuss both the technical and business benefits that come from implementing a data center based on hyperconverged infrastructure.Introduction1These materials are 2019 John Wiley & Sons, Inc.

Foolish AssumptionsIn this book, I assume that you know a little something about virtualization and cloud computing trends and models. As such,this book is written primarily for IT executives and managerssuch as CIOs, CTOs, IT directors, and technical managers.Icons Used in This BookThroughout the book, you’ll find several icons in the margins.Here’s a rundown of what these icons mean.Anything that has a Remember icon is well worth committing tomemory.The Technical Stuff icon indicates extra-credit reading. You canskip it if you like (but I hope you won’t).The Tip icon points out helpful information.The Warning icon alerts you to risks of various kinds.Beyond the BookThere’s only so much I can cover in such little space.

IN THIS CHAPTER»» Understanding what hyperconvergedinfrastructure is»» Discussing the many forms rporate technology undergoes a massive shift every sooften as new models emerge to meet changing businessneeds. This chapter is about hyperconverged infrastructure,which is the culmination and conglomeration of several trendsthat provide specific value to the modern enterprise.Defining Hyperconverged Infrastruc
data center. Hyperconverged infrastructure provides significant benefits: » Data efficiency: Hyperconverged infrastructure reduces storage, bandwidth, and input/output operations per second (IOPS) requirements. » Elasticity: Hyperconverged infrastructure makes it easy to scale out/in resources as required by business demands.
