The National Institute Of Standards And Technology ( Nist ) Defines Cloud Computing

The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of

Modern cloud computing is a delivery system for computing services either for free, or on a pay-as-you-go basis. In this system, users utilize the Internet and remote data centers to run applications and store data. Cloud technology can allow more efficient computing by removing most of the upfront costs of setting up an IT infrastructure. It also allows organizations to expand or reduce their computing facilities very quickly. Increasingly, cloud computing is perceived as a big step toward the long-held dream of computing as a managed utility similar to cable TV or electricity.(Buyya et al, 2010) Cloud computing can be defined by certain criteria. These features are what make cloud computing an attractive option for modern organizations.

The Cloud Computing is one of the fastest growing technology that attracts researchers to add and improve its services [1][7]. Organizations benefit from this technology by replacing traditional IT hardware and data centers with remote, on-demand paid hardware and software services, that are configured for their particular needs, managed and hosted by the organization users or even a third party. This increases the organization’s flexibility and efficiency, without the need to have a dedicated IT staff or owning special hardware equipment or software licenses.

Cloud computing is a one of the most talked of topics in the field of Information Technology in recent times (Keyun, Joe, Taha, & Ibrahim, 2013). This subject area of cloud computing basically is a term used to describe computer resources available as a service accessible over a network (Darren & Kim-Kwang, 2013). The National Institute of Standards and Technology (NIST) define cloud computing as a model for enabling ubiquitous, convenient, on-demand network access on a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction (Peter & Timothy, 2011). Due to the attractive nature of the model there has been rise in the use of cloud computing. Gartner, an IT research and consulting firm, says that cloud computing is growing will become the bulk of IT spend by 2016 (Gartner, 2013).

According to the definition of the U.S. National Institute of Standards and Technology (NIST, 2011), “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction”. This cloud model is collected of five essential characteristics, three service models, and four deployment models. Moreover,

Firms are increasingly turning to cloud computing as a means of managing their IT infrastructure. Notably, the industry is expected to expand 19% to $162 billion by 2020 (Columbus, 2017). This trend can be explained by the business benefits and solutions to problems cloud services including infrastructure, software programs, and platforms as services (IaaS, SaaS, and PaaS respectively) provide.

Cloud computing, or “the cloud”, is defined by NIST as; “...a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.” [1]

Cloud computing has become a major topic of discussion and debate for any business or organization which relies on technology. Anyone connected to the Internet is probably using some type of cloud computing on a regular basis. Whether they are using Google’s Gmail, organizing photos on an Apple iPhone’s photo steam or searching the Web with Bing they are engaged in cloud computing. The interesting thing about cloud computing is it did not start as a technology for the business enterprise, but was driven by the public with services like Facebook. Over the last few years businesses have started to see the value of cloud computing causing it to become a major technology solution for businesses and organizations around the world.

Cloud computing is the delivery of on-demand computing resources which include everything from applications to data centers over the Internet on a pay-for-use basis. Cloud computing is the result of evolution and adoption of existing technologies and paradigms. The goal of cloud computing is to allow users to take benefit from all of these technologies, without the need for deep knowledge about or expertise with each one of them. The cloud aims to cut costs, and help the users focus on their core business instead of being impeded by IT obstacles Cloud computing is so named because the information being accessed is found in the "clouds", and does not require a user to be in a specific place to gain access to it. The services are offered from data centers all over the world, which collectively are referred to as the "cloud." The idea of the "cloud" is to simplify the huge network connections and computer systems involved in online services. Cloud computing is a computing model, not a technology. In this model of computing, all the servers, networks, applications and other elements related to data centers are made available to IT and end users. Cloud computing is a type of computing that is comparable to grid computing. It relies on sharing computing resources rather than having local servers or personal devices to handle applications.

Cloud computing is Internet-based computing, whereby shared information, resources, and software, are provided to terminals and portable devices on-demand. It is a rapidly developing and excellent promising technology. Cloud computing is the product of the combination of grid computing, distributed computing, parallel computing, and ubiquitous computing. Cloud Computing model has enabled IT organizations to serve the users globally. It gives the services like Platform as a Service, Software as a Service and Infrastructure as a Service without users being much aware of the details in which the services are provided.

The largest Buzzword in emerging trends for the computer world is “Cloud”. Cloud computing in the future for data, services and platform. The concept of cloud computing is to make whatever aspect it is being used in available at all times and to act as a resource. Turning computing into a utility will transform how the IT industry uses services, designs hardware and uses network infrastructures. The term “Cloud” however has many meanings, but understanding what exactly is meant by cloud computing is the first step to

In common usage, the term “the cloud” is essentially a metaphor for the Internet. Marketers have further popularized the phrase “in the cloud” to refer to software, platforms and infrastructure that are sold “as a service”, i.e. remotely through the Internet. The major models of cloud computing service are known as software as a service, platform as a service, and infrastructure as a service. These cloud services may be offered in a public, private or hybrid network

Cloud computing have revolutionized life as we know it; it allows people to store, manage, and access their data by using a network of remote servers which are hosted on the internet rather than using a local server or own hardware. A recent study conducted by KPMG found that 81% of businesses were either evaluating cloud services, planned a cloud implementation or had already implemented a cloud strategy [1]. Organizations tend to use the cloud to reduce costs and improve efficiency. Cloud is not a commodity, some people think that it comes out of the sky, while in fact it comes from physical hardware inside brick and mortar facilities which are connected to hundreds of miles by networking cables.

The explanation of “cloud computing” from the National Institute of Standards and Technology (NIST) [2] is that cloud computing enables omnipresent, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. According to the explanation, cloud computing

Cloud computing is an internet based computing that depends on sharing computing with other resources rather than local servers or personal devices to handle applications. Cloud computing has fundamentally changed the way people view computing resources; rather than being an important capital consideration (Navavati, M., Colp, P., Aiello, B., & Warefield, A. (2014)). Cloud computing offers many potential benefits to organizations by making information technology (IT) services available as a commodity. IT services are services provided by IT service provider. Such services includes storing, retrieving, transmitting, and manipulating data for businesses or organizations.
