Anyone with permission can not only access the documents, but can also edit and collaborate on those documents in real time. Unlike traditional puting, this cloud puting model isn’t PCcentric, it’s documentcentric. Which PC you use to access a document simplyisn’t important.But that’s a simplification. Let’s look in more detail at what cloud putingis—and, just as important, what it isn’t.What Cloud Computing Isn’tFirst, cloud puting isn’t network puting. With network puting, applications/documents are hosted on a single pany’s server and accessed over the pany’s network. Cloud puting is a lot bigger than that. It enpasses multiple panies, multiple servers, and multiple networks. Plus, unlike network puting, cloud services and storage are accessible from anywhere in the world over an Internet connection。 they can be public or private.For example, Google hosts a cloud that consists of both smallish PCs and larger servers. Google’s cloud is a private one (that is, Google owns it) that is publicly accessible (by Google’s users).This cloud of puters extends beyond a single pany or enterprise. The applications and data served by the cloud are available to broad group of users, crossenterprise and crossplatform. Access is via the Internet. Any authorized user can access these docs and apps from any puter over any Internet connection. And, to the user, the technology and infrastructure behind the cloud is invisible.It isn’t apparent (and, in most cases doesn’t matter) whether cloud services are based on HTTP, HTML, XML, JavaScript, or other specific technologies._ Cloud puting is usercentric. Once you as a user are connected to the cloud, whatever is stored there—documents, messages, images, applications, whatever—bees yours. In addition, not only is the data yours, but you can also share it with others. In effect, any device that accesses your data in the cloud also bees yours._ Cloud puting is taskcentric. Instead of focusing on the application and what it can do, the focus is on what you need done and how the application can do it for you. Traditional applications—word processing, spreadsheets, , and so on—are being less important than the documents they create.PART 2 Understanding Cloud Computing_ Cloud puting is powerful. Connecting hundreds or thousands of puters together in a cloud creates a wealth of puting power impossible with a single desktop PC._ Cloud puting is accessible. Because data is stored in the cloud, users can instantly retrieve more information from multiple repositories. You’re not limited to a single source of data, as you are with a desktop PC._ Cloud puting is intelligent. With all the various data stored on the puters in a cloud, data mining and analysis are necessary to access that information in an intelligent manner._ Cloud puting is programmable. Many of the tasks necessary with cloud puting must be automated. For example, to protect the integrity of the data, information stored on a single puter in the cloud must be replicated on other puters in the cloud. If that one puter goes offline, the cloud’s programming automatically redistributesthat puter’s data to a new puter in the cloud.All these definitions behind us, what constitutes cloud puting in the real world?As you’ll learn throughout this book, a raft of webhosted, Internetaccessible,Groupcollaborative applications are currently available, with many more on the way. Perhaps the best and most popular examples of cloud puting applications today are the Google family of applications—Google Docs amp
