% What Is Cloud Computing?. Cloud Computing Relies On Sharing

Cloud computing is on the rise. Cloud computing is a style of computing where software and virtualized hardware is provided over the internet (O’Brien & Marakas, 2011). The seven most common uses of cloud computing include: infrastructure as a service, private cloud or hybrid cloud, test and deployment, big data analytics, file storage, disaster recovery and backup (Ferkoun, 2014). The biggest advantages of cloud computing include increasing competitiveness through cost reduction, greater flexibility, and elasticity and optimal resource utilization (Ferkoun, 2014). Cloud computing basically uses the internet to provide for the computing needs of the end users.

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

Cloud Computing is storing of application and data on remote servers accessing through internet instead of installing and saving them on personal computers. Growing huge amount of data which are publicly available has made it impossible to move data to desktop for analysis. To overcome this limitation, we require a new computing paradigm.

Companies can remain agile and quickly build their systems with little delay. “One of the biggest advantages of a Cloud based system is that it can be easily set up in a very short period. The addition of new instances can be performed very quickly. In a cloud environment, software can easily be integrated. Hence, minimum effort is required to customize and integrate the applications.” (K. Pal, 2014).

The national institute of standards and technology (NIST) defines cloud computing as “a model that is meant to enable convenient access to a network that is on demand to a pool of shared computing resources that are configurable” (Jansen & Timothy, 2015). Computer system resources includes, but not limited to, storage, system servers, applications, services, and networks. Cloud computing allows these computing resources to be accessed virtually anytime, anywhere. Cloud computing opens up new possibilities in the field of information technology that many of us have or will experience. As the clients or the customers are very excited about the numerous opportunities that come along with the cloud computing technology such as a reduction in the costs of capital, and the opportunity of divesting themselves of management of infrastructure, and a massive focus on the core competencies, and most importantly, the agility that is usually offered by the provision of computing that is on-demand, there are challenges and other numerous issues that need to be looked into and addressed before a universal adoption might happen (Jansen & Timothy, 2015).

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.

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 computing allows a user to store and access data and programs over the internet instead on their computer hardware (Griffith, 2015). The user is then able to access from anywhere or any internet-enabled device. There are three categories of service in cloud computing: SaaS stands for Software as a Service; IaaS is Infrastructure as a Service; and PaaS is Platform as a Service. Until recently, most users stored and accessed their programs via their hard drive, also known as local storage. What began as an alternative delivery system is swiftly becoming a way for Enterprises to reduce their IT spending while still providing multiple applications to various users. If a service has the following

The report discusses such aspects of cloud computing as its characteristics, deployment models and service models as well as the drivers and challenges of cloud adoption. It also summarizes key differences between cloud computing and traditional IT environments.

Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but

Cloud computing and without a doubt promises to increase the deployment speed , increase innovation, and lower costs while changing the way we design, build, and deliver applications, and the architectural considerations that enterprises must make when adopting and using cloud computing technology.

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 has been a buzz world in the past few years. The use of this technology increased considerably when we made huge progress in this domain, reducing the cost for everyone. Today, Cloud Computing is widely used all across the world by a lot of companies such as Microsoft, Facebook, Amazon, etc…

Cloud Computing is an on demand, flexible and cost friendly delivery platform that has provided IT consumers and organizations services such as networks, storage, servers and applications over the Internet. Its importance is increasing as a large number of industrial and technological communities are rapidly adopting it.

Abstract – Cloud computing is a type of computing that relies on sharing a pool of physical and/or virtual resources (e.g., networks, servers, storage, applications and services), rather than deploying local or personal hardware and software. This technology is mainly service oriented and focuses on cost reduction, hardware reduction and pay just for service concept. Virtualization in cloud computing is making a virtual image of the storage devices servers or network resources so that they can be used on multiple machines at the same time.
