Cloud Computing : A Metaphor For The Internet

Cloud computing is one of the fastest growing segment of Information technology today. In simple words cloud computing means storing and accessing data and programs over the internet instead on the computer's hard drive which can be accessed from any part of the world if the individual are connected to the internet or a network connection is available 24/7. A simple example of cloud computing is g-mail. With the connection of internet through any medium we can send and receive emails.

Cloud computing mainly involves computing inside a network where all the applications or programs can run on many connected PC’s at the same time. All these computers are connected together and are refereed as a server which is then connected through a communication network such as internet, intranet, LAN and WAN.

Cloud computing is the practice of using remote storage for applications and data. The idea itself is not a new one; it has been in use for many years albeit under different names. In the earliest days of the computer age machines had to be physically large to contain the hardware required to do their jobs. It was impractical and prohibitively expensive to provide one of these mainframes for individual users; not to mention for what they were used for, unnecessary. Instead, one central computer was wired to several terminals that users could interface with. Typically, only large organizations such as, major corporations or government agencies could afford one of these machines or had need of one. This was the birth of cloud computing. Until the early 1980s this system was typical for any organization requiring large amounts of processing power. It was considered unnecessary and difficult to put the nuts and bolts of applications onto users’ desktop machines. Rather, by keeping applications in a central location, they could be managed and updated more easily and large amounts of storage space and processing power were not needed on desktop machines. Indeed, before this time there were no desktop machines mass produced that could achieve this level of power. This was about to change.

Cloud computing is a new technology that comes with both benefits and drawbacks and like any new tech it can be used to great success when paired with steps to mitigate the security issues it raises. Cloud computing has become somewhat of an ambiguous term often having different meaning for different people. An article in InfoWorld (2013) stated, ”Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any

Cloud computing is storing and surveying data and programs over the internet rather than the computer's hard drive. Moreover, the cloud is a personification for the internet. It is linked to flowcharts and presentations that epitomize a huge, server-farm infrastructure of the internet as a puffy, white cumulus cloud, acquiring connections and dispensing information as it floats.

Cloud computing is where an individual can save data on a server rather than their own system, such as on their hard drive. This allows more data to be created without it effecting the individual’s computer. An example is one drive by Microsoft.

Cloud computing is innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of

The underlying concept of cloud computing dates back to the 1950s; when large-scale mainframe became available in academia and corporations, accessible via thin clients / terminal computers. Because it was costly to buy a mainframe, it became important to find ways to get the greatest return on the investment in them, allowing multiple users to share both the physical access to the computer from multiple terminals as well as to share the CPU time, eliminating periods of inactivity, which became known in the industry as time-sharing.

The world is turning to cloud computing to manage data. Businesses are at the forefront of this new trend with companies such as Google, Amazon, Microsoft, and others leading the way by providing these services. What exactly is cloud computing? According to Turban & Volonino (2011), cloud computing is Internet- based computing in which shared resources (such as hard drives for storage) and software apps are provided to computers and other devices on- demand (p. 48).

Cloud Computing is a wide term that defines an extended kind of services. In order to actually comprehend how the Cloud can be of worth to an association, it is the first significant to understand what the Cloud truly is and its diverse mechanisms. The different categories of Cloud Computing services normally mentioned to as

Cloud Computing is based from an invention, it allows programs to run and create outcomes in the space of a standard Web browser on a PC. All of the data and applications that are needed are located on a remote server on the Internet. Cloud Computing is Software and also Hardware. This is available to users via the Internet as a service, it allows web based interface through remote access and distribution of computing programs and data resources. (A cloud is also called a Public Cloud when Services are rendered over a network that is opened to public use).The idea of Cloud Computing was created in the (1960s by John McCarthy); “He proposed that computer calculations would someday be made with the maintenance of World Wide Utilities. (Early implementation of Cloud was patented and put to use in (England and Germany) by Hardy Schloer)

Cloud computing is the practice of storing, managing, and processing data on a network of remote servers hosted on the internet, instead of locally on servers or hard drives. Cloud computing has unlimited storage, capacity and scalability, as well as back up and recovery systems. It allows you to access your data anywhere with an internet connection. However, security and privacy is a concern when managing confidential data.

As we all likely already know, there 's a lot of hype associated with cloud computing. Cloud computing encompasses diverse models and technologies. It is not just a paradigm or a concept that is forced into the enterprise by their thought leaders.

The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.

Cloud as the term signifies means the computers in a network to be used for data storage remotely and for maintenance. The cloud computing offers reductions in costs and also has increased scalability, reliability and flexibility in its own processes, and is considered as todays one of the most exciting technologies and has seen a rapid growth over the past ten years. The Cloud computing uses advanced level of computational
