Itroductio The itetio of this book is to provide a thorough referece for those cosiderig a migratio ito the virtualized world. The majority of our target readers will likely be seasoed system admiistrators ad egieers who grew up i ad still maage primarily a hardware-based server eviromet cotaiig a large assortmet of both ewer ad legacy applicatios. As much as we attempt to outlie the graularities of Microsoft virtualizatio as a whole, doe properly, the combiatios ad possibilities are truly edless. The IS world is earig, ad i some cases, has already passed the poit of o retur whe it comes to large-scale virtualizatio implemetatios. Virtualizatio has evolved from somethig fu for ultra-geeks to play with i their spare time, to a solid developmet tool widely used by everybody from high-school studets to goliath software developmet compaies. The ievitable result of this evolutio is a ew way of lookig at eterprise maagemet, for ot oly the dataceter but also all of the compoets used by IS to provide the solutios required by the busiess it supports. The stigma oce placed o the use of virtualizatio by idustry leaders is dimiishig, ad rightly so. We stress throughout the book the importace of proper research ad documetatio. These are two terms commo to the IS world, but rarely used properly. Failure to fully research, uderstad, ad documet your virtualizatio strategy ca easily tur what should be a ejoyable ad very successful trasformatio ito a ightmare for all ivolved. We cover the broad spectrum of Microsoft virtualizatio i a way that will help the IS professioal begi usig virtualizatio i both theory ad practice. Whether you are just begiig your IS career, or you are a seasoed professioal, we hope you fid this book useful i ot oly uderstadig the techology itself but also i learig how to best prepare to use the techology i everythig from a small home-based test lab to a large eterprise productio eviromet. We kew from the begiig that this book would be writte to target our fellow IS peers. The majority of the topics i this book focus o the use of virtualizatio i day-to-day operatios of a eterprise-level IS orgaizatio. We do ot sell Microsoft virtualizatio as the silver bullet to cure all of your IS problems; however, we do feel that the proper use of its collective techologies ca help to alleviate a high amout of iadequacies that plague a large umber of data ceters today. From the small family-owed busiesses to the largest of mega corporatios, there is a aspect of virtualizatio that ca help you to become a more successful IS professioal. Whether it be somethig as simple as usig Disk2VHD to create a backup of a office computer for use i the evet of a uforesee disaster, or somethig as complex as the full implemetatio of Microsoft System Ceter as the framework for maagig thousads of servers, there are beefits to researchig the use of virtualizatio i your eviromet. xvii
xviii Itroductio The true beefits of virtualizatio are ofte uderappreciated, ad i some cases, ot obvious at all to aybody outside of the techical professioal who implemets ad maages it. This ca make the adoptio of virtualizatio a hard sell to those resposible for maagig costs. We discuss this topic at legth i a effort to provide some tools that the IS professioal ca use to promote the implemetatio of virtualizatio through the beefit of icreased efficiecy ad life cycle cost savigs. Usig this book as a referece, you ca begi your dive ito the world of virtualizatio ad start to uderstad the beefits that it may provide for your eviromet. The book will provide you the tools ad explaatios eeded to allow you to create a fresh virtualizatio eviromet. We will walk you through step-by-step istructios o everythig from buildig a Widows 2008 server to istallig ad cofigurig Hyper-V ad App-V. We provide examples of how to publish applicatios i various cofiguratios, as well as detailed explaatios o how to migrate existig servers ito the virtual world, but we will ot be able to show you how to cofigure your eviromet. Every virtualizatio eviromet will be differet. A properly built virtualizatio strategy must take ito accout everythig from the way you cofigure ad maage your servers to how your compay does busiess. Be wary of aybody who promises a shrik-wrapped, plug-ad-play virtualizatio desig for your compay; you must embrace the process of movig ito the virtual world, ad you must be prepared to dig i ad ask the questios that others may be afraid to ask or simply ot kow whom to ask. Virtualizatio techology is truly awe ispirig, which is likely oe of its ow biggest eemies. Before virtualizatio became a maistream techology, it was much easier for maagers ad others resposible for budgets to uderstad the cost of a data ceter, but the days of easily comparig the umber of physical servers with the umber of applicatios or users is quickly becomig a thig of the past. As this evolutio cotiues, you will begi to see budget decisio makers become more ad more depedet o their IS staff to provide reliable iformatio. Be thorough ad cocise, ad uderstad that others will ot likely be able to comprehed the true ature of a virtualized eviromet as you will. Here is a quick outlie of each chapter. Chapter 1: Itroductio to Virtualizatio I this chapter, we discuss the basics of virtualizatio that every IS professioal ad their maagemet should uderstad before jumpig i head first. We talk about the role of virtualizatio i the chagig ladscape of the traditioal data ceter ad its beefits. Chapter 2: Uderstadig Microsoft Virtualizatio Strategies I this chapter, we discuss the strategies of virtualizatio, ad how to begi your approach. We talk about chagig the data ceter from its traditioal cost ceter to a true asset. We touch o the defiitios commo to ay virtualizatio discussio ad explai how virtualizatio exteds far beyod the walls of the data ceter. Chapter 3: Istallig Widows 2008 Server Core ad Hyper-V I this chapter, we cover the step-by-step process used to build a Widows 2008 server, whether you choose the traditioal GUI method or the ewer commad lie (GUI-less) core-istall. With the
Itroductio xix operatig system istalled, we explai the steps take to istall Hyper-V ad get it ready for use. Chapter 4: Maagig Hyper-V I this chapter, we dive ito the process of cofigurig ad maagig a Hyper-V ifrastructure. We examie the various tools icluded i Hyper- V ad how they ca beefit you. We cover the cofiguratio ad use of virtual etworks, ad why you would wat to cofigure them i differet modes. Ad we discuss the differet disk modes available i Hyper-V. Chapter 5: Istallig ad cofigurig Virtual Machie Maager 2008 I this chapter, we talk about Virtual Machie Maager (VMM) ad all of the uderrated fuctioality it provides. We discuss proper VMM library structure ad Hyper-V cosoles that ca be istalled ad used o oserver operatig systems. Chapter 6: Hyper-V ad High Availability I this chapter, we discuss oe of the most highly discussed topics associated with the use of virtualizatio Microsoft s approach to high availability ad how the proper combiatio of Microsoft tools ca be put together i order to provide a very reliable ad highly available virtualizatio ifrastructure. Chapter 7: Creatig Virtual Machies ad Templates I this chapter, we explai virtual machies ad how to best create them. We discuss the importace of proper plaig specific to this fuctioality, ad why you will wat to be especially careful whe creatig virtual machies ad templates. Chapter 8: Performig Physical-to-Virtual ad Virtual-to-Virtual Migratios I this chapter, we discuss the most refereced ad talked about fuctio of virtualizatio; amely, the migratio of physical servers to virtual servers. We talk about the best practices, the importace of vedor support, ad how to prepare for the migratio itself. Chapter 9: Securig, Moitorig, ad Maagig a Virtual Ifrastructure I this chapter, we discuss the methods you will wat to uderstad i securig ad maagig your Hyper-V eviromet. We cover the varyig opiios regardig the eed for security withi the Hyper-V eviromet, ad how you should approach researchig ad applyig this security i your data ceter. Chapter 10: Creatig a Dyamic Data Ceter with Microsoft System Ceter I this chapter, we discuss the Dyamic Data Ceter cocept ad how you ca get there usig the Microsoft System Ceter suite of tools ad cocepts. We revisit the importace of proper plaig ad research ad discuss how virtualizatio for the sake of virtualizig is a bad idea. Chapter 11: Applicatio Virtualizatio I this chapter, we go ito graular detail of settig up a applicatio virtualizatio platform. From the step-by-step build of the server itself, to uderstadig the prerequisites of your App-V farm. Chapter 12: Deployig App-V Packages I this chapter, we demostrate the ease of creatig ad publishig a virtual applicatio withi App-V. We talk about the differet optios available whe publishig a applicatio ad how the differet optios might apply to differet scearios. Chapter 13: Presetatio Virtualizatio (Termial Services) I this chapter, we discuss the highly reovated Microsoft Termial Services ad how this ewer geeratio ca
xx Itroductio provide more efficiet traditioal use, as well as ew fuctioality that may have otherwise goe uoticed. We discuss the Termial Services role i detail ad provide some isight ito how it may help you with maagig your data ceter. Chapter 14: Itegratig Applicatio ad Presetatio Virtualizatio I this chapter, we discuss the ew RemoteApp fuctio available withi the latest geeratio of Termial Services. We talk about how RemoteApp ca be used i associatio with Web Access to provide access to applicatios across the Iteret. Chapter 15: Desktop Virtualizatio I this chapter, we coclude the book with a discussio of desktop virtualizatio ad all of the potetial it provides for a much more streamlied ad efficiet eterprise ladscape of tomorrow. We explai how the techology, although complex, is relatively easy to implemet today, ad why you should cosider it. That is our book i a utshell. We hope you ejoy readig ad usig it as much as we ejoyed researchig ad writig it. Remember that proper research ad documetatio are ot just the key to a successful virtualizatio implemetatio, but key to the success of ay job. Implemetig ad usig virtualizatio are as dyamic as the techology itself, ad virtualizatio is a world that truly defies the phrase it s oly as successful ad complex as you choose to make it. As the use of virtualizatio becomes easier for the ed user, it will udoubtedly become more complex for those who support it, so research the techology regularly ad always verify with peers ad vedors that the approach you followed yesterday is still the right approach to take today.
