The aspects explored are the significant industry questions that have risen about the use of Cloud Computing, business value, organization impact, adaptability, limitations, initial cost of implementation, and the severe business security risks

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 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.

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.

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).

Cloud Computing, also known as ‘on-demand-computing’. It is a computing that based on internet to share resources, information, and data with other devices on-demand. It is a model that enabled everywhere, computing resources such as servers, networks, applications and storages that are configurable can be shared once demand with access and provision rapidly and released with minimum effort of management, and different services are handed through Internet to the computer of organization. Cloud Computing depend on sharing computing resources instead of using personal devices or local servers to handle applications.

Cloud computing is where software applications, data storage and processing capacity are accessed over internet. Organizations use cloud computing in a variety of different service models like IAAS, PAAS and SAAS. These are the three building blocks of cloud computing.

Cloud computing has rapidly increased their services for IT infrastructures solutions in the last years, reducing cost of investment of supplies and maintenance becoming a promising concept in the business and IT industry. The cloud provides shared data center, automatic upgrades, security and performance. However, cloud’s safety and standardization have been a challenge when different types of clouds need to be connected. Resource management issues as Quality of service (QoS) and the increasing of complexity and functionality failures are a constant in cloud computing environments, and should be considered by customer when looking for cloud solutions to adapt their organization’s requirements. This paper will explain the

Cloud computing is a web based utility model. The user does not need to maintain any infrastructure that is to be managed by the provider that is cloud provider. The cloud provides different solutions for the software, platform oriented and the infrastructure. There are three types of services offered which are classified as (IaaS) Infrastructure as a Service, Platform as a service (PaaS) and Software as a Service (SaaS). These services can be deployed by its cloud models that can be private, public, hybrid and community model.

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.

Cloud computing is one of the biggest innovations of the 21st Century. Moving into 2014, cloud computing remains a big IT trend. It is a broad term that covers any type of computing or storage service that is delivered to users from remote servers. This mode of service has technically been in place for years, with online email services being one common example. As technology has progressed, a variety of services can now be provided from the cloud, such as file storage and the ability to run an entire program without having them installed on your computer. Cloud computing allows for pay-per-use or charge-per-use access to applications, software development and deployment environments, and computing infrastructure. Furthermore, it

Cloud Computing is one of the emerging technologies which now represent a reality and a low-cost computing power resource which has gained popularity among all business categories, especially medium and small size, governmental or medical organizations, as more people are realizing the power and benefits of cloud environments. Cloud computing involves deploying groups of remote servers and software networks that allow different kinds of data sources be uploaded for real time processing to generate computing results without the need to store processed data on the cloud. Clouds can be classified as public, private or hybrid

Cloud computing has been ideas as the next generation paradigm in computation. Cloud is an environment of the software and hardware resources in the centers of data that provide diverse services over the network or the Internet to satisfy user’s requirements [1].

With the rapid change in processing and storage technologies and the success in the communication network such as Internet, lessen cost of computing resources, more powerful and more ubiquitously available than ever before. This technological change has enabled the development of a new computing paradigm called cloud computing, in which resources are shared by multiple system over the communication network. Cloud computing is a set of IT services that are provided to a business organizations or customers over a network on a leased basis and with the ability to scale up or down their service requirements. Cloud computing services are delivered by a third party provider who owns the infrastructure. Cloud computing has turned up as a new model for hosting and delivering services over the internet. Cloud computing becomes an attraction in the business world as it does not require plan for provision and business can be set up with a small amount.

“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 composed of five essential characteristics, three service models, and four deployment models.”
