Cloud Based Services Introduction Cloud computing is an Internet-based type of computing through shared computer processing resources. Data is availed through the device on demand. In cloud computing provision of resources is achieved through an Internet connection. Resources shared include servers, storage, services and applications. History of Cloud Computing The term cloud computing was first coined in 1996. However, the idea of sharing computing resources was conceived in the early 1970’s. Cloud refers to an agglomeration of objects, and it is used in cloud computing to refer to a set of things that are used together. In 1977, ARPANET used a cloudlike logo in referencing their network that had interconnected a variety of computer resources. A cluster of servers in the company’s premises looked like a cloud. Their server was circular, and the agglomeration of the servers ended up looking like a crowd. In 1981 CSNET another predecessor also used a cloud symbol for their computing components. In the 1970’s various computing firms popularized a time-sharing concept meant to save computing time. Large vendors such as IBM and DEC adopted a full time sharing option whereby servers would be dedicated to performing one service (Feng et al. 2012). IBM predominately run mainframes. In the 1990’s telecommunication companies started offering data primarily on point-to-point circuits known as Virtual private networks (VPN). VPN was cheaper and offered a better quality of service;

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 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
Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.
Cloud computing is an attracting technology in the field of computer science. Cloud computing is an on demand service in which shared resources, information, software and other devices are provided according to the clients requirement at specific time. It’s a term which is generally used in case of Internet. The whole Internet can be viewed as a cloud.
Many of the techniques of cloud computing, or cloud networking as it often was called, were developed in the 1950s at the Jet Propulsion Laboratory, Massachusetts Institute of Technology, Bell Laboratories, University of Maryland, and a few other research facilities, with application to satellite imagery, wire-photo standards conversion, medical imaging, videophone, character recognition, and photograph enhancement.[1] The cost of processing was fairly high, however, with the computing equipment of that era. That changed in the 1970s, when digital image processing proliferated as cheaper computers and dedicated hardware became available. Images then could be processed in real time, for some dedicated problems such as television standards conversion. As general-purpose computers became faster, they started to take over the role of dedicated hardware for all but the most specialized and computer-intensive operations.
Cloud computing means on demand delivery of IT resources via the internet with pay-as-you-go pricing. Cloud computing is a virtualization based technology that reduces the cost of IT infrastructure. It provides a solution of IT infrastructure at low cost. It also focuses on maximizing the effectiveness of the shared resources. Cloud resources are usually not only shared by multiple users but are also dynamically reallocated per demand.
much complex share of resources hosted over the internet, coined as Cloud Computing in the
Cloud computing is a style of computing that provides easy access to a highly configurable pool of resources which are simple to use
In computer networking , cloud computing is computing that involves a large number of computers connected through a communication network such as the Internet , the same as utility computing . In science , cloud computing is a synonym for distributed computing over a network, and that means the ability to run a program or application on many computers connected at the same time .
Now with the same ubiquity that is mentioned as above, there is this rampant need for adopting virtualization and separating software from hardware because the recent catalysts of changing culture in mobility and the flexible, scalable nature of enterprise needs presents before it the option of procuring what it needs, when it needs. Then when the user found the need to expand, it also found the need to divert and so re-allocation of resources and moving one’s safety critical data beyond its four walls and a lot of the attention slowly shifted from converting their fixed costs to their variable costs. So if organizations, find underutilized resources in the
The lack of a clear and widely accepted definition has posed a barrier to talking about cloud computing in general. Clearly “cloud computing" is an evolving term, defined more by usage than by
Cloud computing has gained significant popularity over the past few years because of its self service capacity, flexibility, affordability, scalability and its pay as you go service model. You may have also heard cloud computing referred to as the cloud, cloud hosting, cloud server hosting and etc. These terms have been thrown around so much and most do not even know exactly what it means. So what is cloud computing?
