1 1 of 9 07/07/ :12 Module 2 Cloud Computing Module 2 Cloud Computing "Spending on IT cloud services will triple in the next 5 years, reaching $42 billion worlwide." In cloud computing, the word "cloud" is used as a metaphor for "the Internet," so the phrase "cloud computing" is used to mean a type of Internet-based computing, where services (such as servers, storage, applications and so on) are delivered to the users computers and devices through the Internet as an on-demand service. There is no more installing and updating software on your own computer. You will simply log onto the site that runs the service and will do your creating/saving/editing/ in the cloud. Many of the cloud computing services are free and this and other modules in the course will look at some of these services.

2 2 of 9 07/07/ :12 Intoduction What exactly is Cloud Computing? Cloud Computing is a term that is often bandied about the web these days. So just what is Cloud Computing? A basic definition of cloud computing is the use of the Internet for the tasks you perform on your computer. The "cloud" represents the Internet. Have you ever used Hotmail or Facebook? Then you have used the Cloud. You have used software (an account for example) that is not installed on your computer. You have saved information onto a computer other than your own. This is the essence of Cloud Computing. It is about using the internet - the Cloud - to access programs that are not stored on your computer. Some people would say that Cloud Computing is really just hype for what many people already do. Others see it as a fundamental shift away from the traditional way of using your PC. In this module we are going to look at a cloud computing service that is being widely used by pupils and teachers worldwide. This application is called Google Docs and is like on online office suite that lets you create documents, spreadsheets, presentations and forms. You don't install anything on your computer and all the files you create are stored securely online as opposed to on your computers hard drive. All of Google Docs features are accessed through any internet connected computer. You can also share your documents with others and so several people can work collaboratively on the one document.

4 4 of 9 07/07/ :12 Getting Started With Google Docs Since its introduction in 2006, Google Docs has changed the way people think about office productivity tools. First word-processing documents and spreadsheets and then slideshow-style presentations (which made their Google Docs debut in 2007). Unlike traditional productivity applications, which you buy, install on your computer, and later upgrade yourself (for an additional fee), Google Docs' applications are Web-based. That means your documents, spreadsheets, and presentations are stored on the Web, and you can access them from anywhere you have an Internet connection and a Web browser. Imagine the possibilities: No more having to remember to transfer a file from your desktop computer to your laptop before you hit the road. No more wondering whether the version you're working on is the current version. No more having to back up all your documents because Google stores them securely online. But one of the greatest advantages of Google Docs is the ability to share your documents with others and collaborate on them in real time. If you've ever collaborated by ing a flurry of files or waiting for someone else to give you a document on a usb pen drive, you'll love collaborating in Google Docs. When you share a document with some collaborators, those people can sign in and work on the document whenever they want, from wherever they are. Multiple collaborators can work on a document at the same time. All edits happen to the current version of the document, so you never have to worry about working on an out-of-date file. If someone makes edits you need to undo, you can roll back to a previous version using Google Docs' revision history feature. Best of all, Google Docs is free. Yes, you heard that right-it won't cost you a penny to use. There's nothing to install on your computer, and Google takes care of fixing bugs and updating the applications. It's no wonder that millions of individuals are choosing Google Docs to create, edit, and store their documents. To see an overview of what google docs offers watch the following video.

8 8 of 9 07/07/ :12 Sharing Documents With Google Docs The preceding section and videos have shown that the Google Docs word processor, spreadsheet and presentation applications are convenient, flexible, powerful, and easy to use. This section shows you what makes Google Docs revolutionary, going to the heart of how Google has changed the landscape of document creation: the ability to share a document with others, collaborating on it simultaneously in real time. Whether you're planning the itinerary for a family reunion, working on a group report for class, or putting together a project specification for work, collaborating on a shared document means that everyone who shares the document always has the latest version right at their fingertips. And you can work more efficiently because several people can edit the document at the same time-no more waiting for a document to be checked back in before you can work on it or wondering who's going to merge the changes three different editors made.
