Cloud Computing

   I am pretty sure that everyone reads this blog have some sort of experience regarding to cloud computing. At least if you have use web based mail it will be enough to understand what  really cloud computing is. Instead of having e-mail program that running on user computer,user log in to web based application that able to access it remotely. It is obvious that the software and storage for the mail doesn't exist on users computer. Actually it is on the cloud computer. Cloud computing is generally designed to use for networks,servers,storage application and services.

  Let's think you are the owner at some computer based company. If you have 50 computers normally you will have to buy 50 operating systems software for the each computer. Fortunately after introduction of cloud computing, you will only have to have one software for all the 50 computers. As same as adding some functionalists, make changes for the cloud computer will be appear on the users computer's as well. To access cloud computer user will have to have simple program that called interface software which is slimier to web browser. Furthermore this will result to spend less money to do the same work. And it is very secure and reliable.
 
  Additionally if we talk about large companies they are getting theses benefits from cloud computing.

• Will be able to save space for physical storage.
• High reliability and availability
• Heavy load variation 
• World wide distribution

  Working with computer sometimes makes the question how we can relay on a machine. User data can be damaged, deleted due to error occasions. Data records can be priceless to user or company. Cloud computing is a good solution for the above problem. Mainly user's computer and  the cloud computer connect by the internet. If the user has internet connection he or she will be able to use the data from any place in the world.

  The other good thing about cloud computing is security option. If  the user have data in personal computer or in a external storage device it might be easy to lose or stolen by someone. As a user of cloud computing you will have minimum risk for who will be reading your important data. Furthermore sharing option helps user to select what information needs to share and with whom.

  As a result of cloud computing lot of advance technologies have arrived. Good examples are tablet PC and smartphones. Actually these items do not contain hard disks at all. But they are capable of doing all the tasks smoothly. So, cloud computing was helped to make these devices very cheep and small. As I mention earlier, users don't need to worry to much about data losses. Everything will be restore after few commands. 

  

   Cloud computing has highly impact for computer science field. It is correct that cloud computing has changed the direction of computer science.
