  2. 2. What is ‘The Cloud’ <ul><li>The Cloud is actually a warehouse full of computers, called a server farm. </li></ul><ul><li>There are many server farms around the world. </li></ul><ul><li>Sometimes your data can be stored in a multiple number of different server farms at one time. </li></ul>
  3. 3. What is ‘The Cloud’ continued <ul><li>This allows you to access your data wherever you are at any time, from any computer which has access to the internet. </li></ul><ul><li>This means that you no longer have to worry about having the correct software on the computers you use. </li></ul><ul><li>With the introduction software is now available online for free. </li></ul>
  4. 4. What is ‘The Cloud’ continued <ul><li>Cloud Computing is in a constant state of evolution, where software is always being updated. This is similar to most beta services. </li></ul><ul><li>This is because third parties are able to contribute and improve software that major companies have produces, for example Google Mail </li></ul>
  5. 5. Different Type Of Clouds <ul><li>Public Cloud : This is the standard conventional version of cloud computing, which is used on a self service basis. This allows anyone in the world to use services provided by other people </li></ul><ul><li>Private Cloud : This is similar to the conventional cloud formation. This allows access to all cloud facilities which is only accessible to certain amount of people e.g. Blackboard </li></ul><ul><li>Hybrid Cloud: This is essentially a fusion of both a Public and Private Cloud which provides resources internally and also uses external web based resources. E.g. My DMU Email </li></ul>

  7. 7. <ul><li>Google wave is an in development program which combines elements of Google Docs with instant messaging services </li></ul><ul><li>People are able to communicate, and edit documents in real time, as well as send pictures, videos and maps. </li></ul>
  8. 8. Facebook <ul><li>Facebook is a social networking site which also uses cloud computing. </li></ul><ul><li>You are able to store videos and photos online and have other users view and comment and ‘tag’ your pictures. </li></ul><ul><li>This is good because your are able to store these on a outside server. </li></ul>

  10. 10. Google vs. Netscape <ul><li>Netscape used web as a platform. There aim was to create and sell software, in order to have the monopoly in this sector. </li></ul><ul><li>There software for the use of the individual. The programs were put on to your personal computer. Google became Netscape’s major competitor. </li></ul>
  11. 11. Cont.. <ul><li>Netscape lost it market share as a result of Google’s uses of free services. And as you did not have to buy updates. </li></ul><ul><li>Google made it possible for people to ‘cloud compute’ as the information that we seek is now on a large database that is accessible to all. </li></ul>
  12. 12. Advantages <ul><li>Cost: You no longer need to buy the latest software, and the risk of bugs in the first wave of software. </li></ul><ul><li>Speed: You are able to rapidly update and change software and documents. </li></ul><ul><li>Reliability: due to constant updates, bugs and technical glitches are found and corrected quickly. </li></ul>

  14. 14. Disadvantages <ul><li>Security: Because your personal files are no longer stored on your computer it is easier for an outside party to use your data for their own personal needs i.e. Identity Theft </li></ul><ul><li>If the server farm suffers a disaster (fire) your data could be lost and unable to be recovered </li></ul><ul><li>Accessibility: If you are unable to access the internet, Cloud Computing is useless. </li></ul>
  15. 15. Conclusion <ul><li>Cloud computing can be seen as the next step in the evolution of file management, but it could also be seen as the death of ‘personal’ computing. </li></ul><ul><li>In one form or another it is probably already in our lives. </li></ul><ul><li>Only time will tell if Cloud computing will be accepted and used by the general public. </li></ul>
