History and Features of Cloud Computing

This section of the article describes cloud computing as a group of computer systems connected over a public or private network that provides dynamically scalable infrastructure (equipment and software) for application, data and file storage. This means that the cloud can be easily modified to add or remove resources and infrastructure as needed. In continuing with the overview, the article notes that cloud computing is an innovative approach to traditional computing methods that can be utilized through the different cloud models.

Cloud computing can be viewed as one of the most rapidly growing and evolving paradigm.Webmail,online storage and online documents are most famous examples in which customers can access their data via web browsers on the internet. The original idea of the cloud computing was delivered by J.C.R Licklider in sixties (Mohamed 2009). Cloud computing has developed since then and started to server the publics after internet offered a significant bandwidth in the nineties (Mohamed 2009). Cloud computing has been through many different phases and is still rapidly evolving.

The word "cloud" is used to represent the internet and other communications systems. Cloud computing is the result of an evolution of the widespread adoption of virtualization, service-oriented architecture, autonomic, and utility computing in the past, telecommunications companies mainly gave simply dedicated, point-to-point data circuits to their users. Starting from the 1990's, virtual private network services was included in their contributions. It made the telecommunication companies offer equally improved services whereby cutting down on cost as well as using resources effectively.

Cloud Computing appears as a computational paradigm as well as a distribution architecture and its main objective is to provide secure, quick, convenient data storage and net computing service, with all computing resources visualized as services and delivered over the Internet [2,3]. The cloud enhances collaboration, agility, scalability, availability, ability to adapt to fluctuations according to demand, accelerate development work, and provides potential for cost reduction through optimized and efficient computing [4].As the data

Cloud computing can be understood as a multifaceted infrastructure of hardware, software, storage and processing available to be used as a service. With the use of cloud computing, without even knowing how it works, one can access a large number of the most sophisticated supercomputers of the world and their respective processing powers without being overwhelmed with space or information. Cloud computing allows access to computer networks located at various places in the world and thus offers the speed of

Cloud because of its wide range of applications it allows users to store data their data remotely in the cloud and enjoy the on-demand high quality cloud applications and reveal burden from the local storage, cost and maintenance. In this according to the user’s perspective, including both individuals (private) and enterprises like companies appealing the cloud benefits by storing data remotely into the cloud in a flexible on-demand manner and relief of the burden of storage management along with this he/she can also enjoy the universal data access which dependent geographical locations and avoidance of the capital expenditure, software, hardware and personnel management and maintenances and so on.

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

Recently, Cloud technology has turn out to be a huge buzzword, and with good reason. The cloud already creates remarkable value for clients and businesses by making the digital world simpler, faster, more powerful, and more efficient. In addition to bringing valued Internet-based services and applications, the cloud can provide a more

server, load software on it, turn it on and off or clone it to meet a sudden workload demand. It

Cloud computing is more advantageous to this sector. It’s one of the easiest and fastest service in order to advertise and spread fame. It helps in spreading the name of services and get fame in the market with in a very short period. The software as well as hardware related issues occurred in this field are solved to a great extent by the cloud computing. It improves the platform and provides the security to the data stored in the cloud.

Cloud computing is the new buzz in the recent days and cloud computing allows users to share files and applications over the internet. In the following pages we will discuss about the cloud computing its pros and cons, the security risk and how to overcome and use its resources for the best advantage of organizations. It is attracting much of the attention now-a-days which can be seen by observing the big names of the IT industry like IBM, Microsoft and Google investing millions of dollars into research on cloud computing.

Through the use of the Internet and remotely located servers, cloud computing’s technology allows companies to save money, by eliminating the need to maintain servers and other hardware locally. Having a central location for files, applications, and servers; companies benefit by saving money they would have otherwise invested in equipment maintenance, bandwidth, storage (hard drives), and memory use.

With the ability to be more flexible, require less overhead, and access the data anywhere in the world (usually), cloud computing is becoming an increasingly popular option, offering a wide array of services and solutions. These services and solutions, although unique, generally have the same essential characteristics. The five essential characteristics, as defined by NIST, are:

The world has recently adopted a new approach to computing – cloud computing. It is a particularly new model of computing, where databases are stored and operated somewhere in a cloud. Mell and Grance (2011) define cloud computing as “a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction” (p. 2). In other words, the cloud is considered a remote computing data center that one can access either on the subscription or “pay-as-you-go” basis. Thus, cloud computing relates to the hardware, applications, and system software that provide

After couple years cloud computing became extremely powerful, since in 1990’s Internet started to offer significant bandwidth, which made it possible to maintain huge amount to storage outside of personal hard drive.
