How Cloud Computing Works !!! A question that is arising in everyone’s mind. As a well-known metaphor referring to the Internet, the “cloud” symbolizes a virtual space in which users from all over the world can share information by accessing networks of satellites. Cloud computing simply represents another term for resource, data and software sharing via the Internet. A cloud computing provider, facilitates control and maintenance of information by storing this information on physical servers.
How Cloud Computing Works ???
When someone utilizes cloud computing, he or she is essentially storing data somewhere else instead of their hard drive. Enlisting the assistance of cloud computing means that a user is able to access information from anywhere and download it to a variety of devices, such as smartphones, laptops and tablets. Because users are sharing this “cloud” with others, simultaneous editing of documents, files and even power points is entirely feasible, making completion of work while not physically in the office much more expedient.
Cloud Computing Examples :
Recently becoming a sort of buzzword in the digital world, cloud computing has actually been used for quite some time. Typing queries into a search engine results in words being rapidly transmitted over the Internet and into a huge assembly of clustered personal computers that extract relevant results to be sent back to the user. In other words, the work isn’t being done by the user’s computer but by other computers located halfway across the globe
Another example is email. Originally, users had to have a mail client program installed on their computer in order to send and receive email. Today, we have web-based email services like Gmail or Hotmail which employ cloud computing technology to handle millions of user email needs.

Whenever remotely stored information can be accessed at any time from any location, the platform being used is considered a cloud computing platform. Other familiar examples of cloud computing include Google Documents, Facebook and Microsoft’s Skydrive.
Advantages to Cloud Computing :
Users do not have to worry about malware infecting their computer or losing files due to destructive viruses
Cloud services are accessible as a “pay as you go” service or on-demand. Services that aren’t touted as cloud computing services like Hotmail are free
Access to information stored in the cloud is available anywhere as long as an internet connection exists
Users have access to unlimited storage space, as opposed to being forced to perform upgrades on a computer’s memory drive or obtaining an external hard drive on which to place large blocks of information
Software associated with a cloud server is automatically updated
Disadvantages of Cloud Computing :
Some people may not feel comfortable relying on a service provider to “keep” their valuable information in the cloud and separate from their own computer
Although cloud service providers employ stringent security devices to prevent shared data from being hacked or accidentally leaked, the possibility always exists that a security breach may occur
If the server is down, the user does not have access to his or her information. A permanently grounded “cloud” means that the user has probably lost all the data he stored in that server.

The rising popularity of cloud computing suggests that users are experiencing more benefits than problems with cloud service providers. Tech insiders suggest that, in the future, the widespread use of cloud computing will lead to the extinction of USB memory sticks and computers containing large amounts of memory space.
