    • Definition of Cloud Computing “Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications”
    • Introduction  With traditional desktop computing, we run copies of software programs on our own computer. The documents we create are stored on our own pc.  Although documents can be accessed from other computers on the network, they can’t be accessed by computers outside the network. This is PC-centric.  With cloud computing, the software programs one use aren’t run from one’s personal computer, but are rather stored on servers accessed via the Internet.
    • Introduction  If a computer crashes, the software is still available for others to use. Same goes for the documents one create; they’re stored on a collection of servers accessed via the Internet.  Anyone with permission can not only access the documents, but can also edit and collaborate on those documents in real time.  Unlike traditional computing, this cloud computing model isn’t PC- centric, it’s document-centric.
    • What Is Cloud Computing?  Key to the definition of cloud computing is the “cloud” itself. Here , the cloud is a large group of interconnected computers.  These computers can be personal computers or network servers; they can be public or private.  This cloud of computers extends beyond a single company or enterprise. The applications and data served by the cloud are available to broad group of users, cross-enterprise and cross-platform.  Access is via the Internet. Any authorized user can access these docs and apps from any computer over any Internet connection.
    • Key properties of cloud computing: Cloud Computing Is User Centric Cloud Computing Is Task-Centric Cloud Computing Is Powerful Cloud Computing Is Accessible Cloud Computing Is Intelligent Cloud Computing Is Programmable
    • Cloud Computing Is User Centric : Once as a user are connected to the cloud, whatever is stored there—documents, messages, images, applications, whatever—becomes authorized to the user access them. In addition, not only is the data, but one can also share it with others. In effect, any device that accesses your data in the cloud also becomes yours. Cloud Computing Is Task-Centric: Instead of focusing on the application and what it can do, the focus is on what one need done and how the application can do it for us. Traditional applications—word processing, spreadsheets, email, and so on—are becoming less important than the documents they create.
    • Cloud Computing Is Powerful: Connecting hundreds or thousands of computers together in a cloud creates a wealth of computing power impossible with a single desktop PC. Cloud Computing Is Accessible: Because data is stored in the cloud, users can instantly retrieve more information from multiple repositories. We are not limited to a single source of data, as we do with a desktop PC.
    • Cloud Computing Is Intelligent: With all the various data stored on the computers in a cloud, data mining and analysis are necessary to access that information in an intelligent manner. Cloud Computing Is Programmable: Many of the tasks necessary with cloud computing must be automated. For example, to protect the integrity of the data, information stored on a single computer in the cloud must be replicated on other computers in the cloud. If that one computer goes offline, the cloud’s programming automatically redistributes that computer’s data to a new computer in the cloud.
    • How Cloud Computing Works? Sun Microsystems’s slogan is “The network is the computer,” and that’s as good as any to describe how cloud computing works. In essence, a network of computers functions as a single computer to serve data and applications to users over the Internet. The network exists in the “cloud” of IP addresses that we know as the Internet, offers massive computing power and storage capability, and enables wide scale group collaboration.
    • Understanding Cloud Architecture: Individual users connect to the cloud from their own personal computers or portable devices, over the Internet. To these individual users, the cloud is seen as a single application, device, or document. The hardware in the cloud (and the operating system that manages the hardware connections) is invisible.
    • Cloud Architecture
    • Understanding Cloud Storage: One of the primary uses of cloud computing is for data storage. With cloud storage, data is stored on multiple third-party servers, rather than on the dedicated servers used in traditional networked data storage. When storing data, the user sees a virtual server—that is, it appears as if the data is stored in a particular place with a specific name. But that place doesn’t exist in reality. It’s just a pseudonym used to reference virtual space carved out of the cloud. In reality, the user’s data could be stored on any one or more of the computers used to create the cloud.
    • Understanding Cloud Services: Any web-based application or service offered via cloud computing is called a cloud service. Cloud services can include anything from calendar and contact applications to word processing and presentations. With a cloud service, the application itself is hosted in the cloud. An individual user runs the application over the Internet, typically within a web browser. The browser accesses the cloud service and an instance of the application is opened within the browser window. Once launched, the web- based application operates and behaves like a standard desktop application.
    • • Several Major companies are jumping at the chance to offer services for this new revolution of computer technology. • It is said to be as big of technology as the internet.
    •   The leader in cloud computing. Google offers several services including e-mail and document creating applications.  Google claims its services are 99.99% reliable.  Though users have experienced downtime.
    •  Amazon offers companies data storage services.  Companies only have to pay for the storage they use.   More and more companies are starting to trust cloud computing services and turn begin to store their data in the clouds. It appeals to companies because it eliminates time employees spend on maintaining this data and eliminates maintenance.
    •    The cloud computing industry is predicted to hurt the software business. Therefore Microsoft is taking a stand and developing cloud computing services of their own, Azure. They are offering Microsoft based document applications for the web for a small monthly fee.
    • • Even the government is wanting to get in on this new technology. • The US Defense Department is offering a new cloud computing service to its military users called RACE. • They claim their services are more reliable and secure because security is their # 1 policy
    • • IBM are developing cloud computing applications for the everyday user called CloudBurst. • There has also been some talk of IBM coming together with Sun Microsystems to enhance their ability to build data centers for this new technology. • IBM also offers “private” cloud computing services using IBM blue services software. – Instead of putting information out on the internet it makes the companies data center into its own cloud. This cloud is blocked off from the internet using firewalls.
    • Benefits From Cloud Computing:  Collaborators: The ability to share and edit documents in real time between multiple users is one of the primary benefits of web-based applications; it makes collaborating easy and even fun.  Road Warriors: You can access a single version of your document from any location.  Cost- Conscious users: Another group of users who should gravitate to cloud computing are those who are cost conscious. With cloud computing you can save money on both your hardware and software.
    • Security Issues • Some people are still skeptical about this new technology. • Why should you trust some company with your private information or your companies’ information? • Should you just put information out there? • Is it safe or can someone hack into the “cloud” easier than into your computer? Also is it reliable? • Will you always be able to access this information?
    • Thus cloud computing provide a super-computing power. This cloud of computers extends beyond a single company or enterprise. The applications and data served by the cloud are available to broad group of users, cross-enterprise and crossplatform.
