Yet a swell in media and analyst coverage, plus a proliferation in cloud computing providers and marketing messages, has resulted in a great deal of confusion about what the term “cloud computing” really means. For example, some providers look at cloud computing as way to provide compute or storage capacity as a service, provi- sioned from a parallel, on-demand processing platform that leverages economies of scale. Others may equate cloud com- puting with software as a service, a delivery model for making applications available over the Internet. IT analysts view cloud computing from the perspective of variable pricing without long-term commitments and massive elastic scaling of services. IT leaders look at cloud as an infrastructure architecture alternative that...

...The power of cloud You can hardly look at an IT strategy document today without seeing mention of cloud computing, even though it has been around for years. This model has now crossed the chasm to penetrate corporate America, which traditionally relied on internal infrastructure. This is a significant shift in IT mindset in what will certainly be remembered as a disruptive technology strategy that changed the way the world works, literally. What is cloud? Cloud computing is a pay-per-use consumption and delivery model that enables real-time delivery of configurable computing resources (for example, networks, servers, storage, applications, services). Typically, these are highly scalable resources delivered over the Internet to multiple companies, which pay only for what they use. Cloud delivery models can help organizations scale their investments as they grow their business. They can also open the door to new business approaches through standardized applications, infrastructure, testing environments and business processes that help improve service delivery and efficiency. Although cloud is widely recognized as a technology game changer, its potential for driving business innovation remains virtually untapped. Indeed, cloud has the power to fundamentally shift competitive landscapes by providing a new platform for creating and delivering business value. To take advantage of cloud’s potential to transform internal operations, customer relationships and industry value chains...

It joins the ranks of ‘virtualization’, ‘grid computing’, and ‘clustering’, among other buzz words in the IT industry. Cloud computing is a virtual network access, application, storage, and other computing resources on a pay-as-you-go basis. It allows users to access their networks, store information, and other resources from a virtual “cloud.” It is a relatively new concept that is still evolving. As a result, there is no standard definition of the cloud computing concept, which has led to many variations of the definition of cloud computing. Due to this lack of standardization members of the IT industry have created cloud products based on their own definitions of cloud computing, which has resulted in inconsistencies and confusion about what cloud computing really is. This paper will discuss the evolution, various definitions, deployment models, delivery models, characteristics, benefits and risks, of cloud computing. Evolution of Cloud Computing Cloud Computing has evolved through a number of phases, which include grid and utility computing, application service...

...security, organizations must adopt an approach that is both holistic and proactive. This decision traditionally involves an evaluation of the business processes involved, assessment of compliance with regulations and standards, and the identification of information systems and technology capability. Cloud Computing has become one of the most discussed and sought after solutions for dealing with such challenges. According to IDC Cloud, research suggests that IT Cloud Services spending will reach $47.4 billion in 2013 and is expected to be more than $107 billion in 2017 with an annual growth rate of 23.5 percent, five times that of the industry (IDC, 2013). Cloud Computing is a resourceful model that allows enterprises to accelerate innovation, decrease infrastructure costs, improve resource utilization, and greater ability to manage information technology security (PwC, 2010). The “Cloud” refers to the Internet, a collection of interconnected networks that communicate with each other, and it can be accessed globally. Cloud Computing employs network resources to deliver services entirely online. The National Institute of Standards and Technology defines Cloud Computing as: “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” (Mell, 2011)...

As technology developments are increased significantly, many individuals and businesses are interested to use software and hardware services that are managed by third parties at remote locations (Mirzaei, 2008). The term “ cloud “ can be truly understandable how the cloud can be a value to an organization by providing various services like online data storage, social networking, online business applications and webmail’s etc. because, the cloud computing allows access to information and computer related resources from any location that has network connection (Mirzaei, 2008). 2. Components of Cloud Computing: 2.1 Cloud Client: Clients play a key role in providing access for users to client devices which consists of computer software and hardware that depends on cloud computing for application delivery. And also there are several applications which are designed specifically for delivery of cloud services and it is essentially useless without the application. For example which can include devices like computers, mobile phones and applications like operating systems, browsers etc (Nichols, 2011). The cloud client has three different types, they are * Mobile clients. * Thick clients (Nichols, 2011). * Thin clients (Most popular) (Nichols, 2011). 2.2 Distributed Servers:...
