    Cloud Computing Cloud Computing Presentation Transcript

    • What is Cloud Computing?
      • Cloud Computing is one of the most integral aspects of Web 2.0.
      • As it allows you to store your important documents, pictures and videos online instead of on your personal computer.
    • What is ‘The Cloud’
      • The Cloud is actually a warehouse full of computers, called a server farm.
      • There are many server farms around the world.
      • Sometimes your data can be stored in a multiple number of different server farms at one time.
    • What is ‘The Cloud’ continued
      • This allows you to access your data wherever you are at any time, from any computer which has access to the internet.
      • This means that you no longer have to worry about having the correct software on the computers you use.
      • With the introduction software is now available online for free.
    • What is ‘The Cloud’ continued
      • Cloud Computing is in a constant state of evolution, where software is always being updated. This is similar to most beta services.
      • This is because third parties are able to contribute and improve software that major companies have produces, for example Google Mail
    • Different Type Of Clouds
      • 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
      • 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
      • 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
    • Google Docs
      • Google Docs is a web based application which utilises cloud computing.
      • In Google Docs you are able to upload work documents such as spreadsheets, essays etc. and allows users in your network to view and edit those documents online.
      • Google wave is an in development program which combines elements of Google Docs with instant messaging services
      • People are able to communicate, and edit documents in real time, as well as send pictures, videos and maps.
    • Facebook
      • Facebook is a social networking site which also uses cloud computing.
      • You are able to store videos and photos online and have other users view and comment and ‘tag’ your pictures.
      • This is good because your are able to store these on a outside server.
    • Youtube
      • YouTube is a video sharing website where users are able to upload videos of any content which can be viewed by anyone.
      • People are able to view and comment on the videos that you have posted. They can also recommend videos based on your interests.
      • In January 2009 alone 14.8 Billion videos were viewed worldwide.
    • Google vs. Netscape
      • Netscape used web as a platform. There aim was to create and sell software, in order to have the monopoly in this sector.
      • There software for the use of the individual. The programs were put on to your personal computer. Google became Netscape’s major competitor.
    • Cont..
      • Netscape lost it market share as a result of Google’s uses of free services. And as you did not have to buy updates.
      • 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.
    • Advantages
      • Cost: You no longer need to buy the latest software, and the risk of bugs in the first wave of software.
      • Speed: You are able to rapidly update and change software and documents.
      • Reliability: due to constant updates, bugs and technical glitches are found and corrected quickly.
    • Advantages cont.
      • Accessibility: Documents, pictures, videos can be uploaded, viewed, edited at home, work, even on select mobile phones.
      • Security: If your computer goes down, or crashes your personal documents is safely stored in the cloud
    • Disadvantages
      • 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
      • If the server farm suffers a disaster (fire) your data could be lost and unable to be recovered
      • Accessibility: If you are unable to access the internet, Cloud Computing is useless.
    • Conclusion
      • 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.
      • In one form or another it is probably already in our lives.
      • Only time will tell if Cloud computing will be accepted and used by the general public.
