What is Cloud computing is a big topic and how it all works in real-time is not too difficult to comprehend. Storage and sharing of files have undergone a dramatic and drastic evolution over the last few decades, starting from floppy disks to compact disks to USB drives. The file-sharing devices are becoming smaller in size with higher capacities, designed increasingly to serve a busy on-the-go schedule. The concept of saving all documents on one specific device is no longer practical. Instead, one can access his files from anywhere at any point of time, courtesy “Cloud computing”.
The Concept of Cloud Computing:
The “Cloud” has always served as a metaphor for the internet. Cloud symbols, in fact, are generally used to signify the internet on any diagram. The internet, as a virtual space connecting users from all across the globe, is like a cloud, effectively sharing information via satellite networks.
Storing and Sharing Data on Cloud – Here’s how:
Cloud computing refers to sharing of resources, information, and software through a network which in this case is the internet. The info is saved on physical servers controlled and maintained by a Cloud computing service provider, e.g. Apple in case of iCloud. A user accesses his stored info on the Cloud through the internet. Use of cloud storage does not require one to store his information on his own hard drive. Rather, he can access it from anywhere and download it onto any device of his choice including smartphones, tablets, or good old laptops. Moreover, a user is also able to edit files like PowerPoint presentations or Word documents, along with other users, thus making it easier for all to work out of office.
There are varying types of Cloud computing services that suit various needs. While some are designed for companies that require extensive platforms for developing IT applications, others cater to individual users who need to store documents, pictures, and videos.
Prices vary, depending on the needs. An individual user can get a primary amount like 5GB of storage free with iCloud. One needs to pay a fee if he needs an additional storage. Fees are generally set at yearly or monthly rates, depending on the services one is using.
Pros of Cloud Computing:
- Global Access: Cloud computing enhances mobility as one can access his documents from any corner of the world and on any device. For enterprises, this enables employees to work on business trips or from home, without needing to move around with cumbersome documents. This enables rapid exchange of info and thus increases productivity. Employees are also able to work on the same files without having to be physically present at the same place.
- Increased Storage: Memory, in the past, was restricted within the specific device at hand. On running out of memory, one needed a USB or flash drive for backing up his device. Cloud computing offers more storage so that one does no longer have to worry about running out of space on his hard drive.
Cons of Cloud Computing:
- Security:One is essentially handing over his data to a third party, while using a Cloud computing service. The fact that users from all over the globe as well as the entity are all accessing the same server can definitely cause a security concern.
The concept of Cloud computing and how does it work is important to understand as the cloud technology is going to stay and grow over the coming decades.
