Essay on Cloud Computing Benefits , Challenges and Future.

This case gives us a fundamental understanding of the concept of cloud computing and presents the advantages and issues of this IT infrastructure. This case gives a clear vision of the company’s current situation. Three main questions to consider

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

In today's business applications, management has to embrace cloud computing for them to succeed in the highly competitive world. Cloud computing is the latest technology that allows provision and use of IT infrastructure, and applications which are readily available on the Internet. Cloud computing provides information over the web thus businesses will have no need for hardware or software on the consumer side. Cloud services are hosted on the Internet and businesses can pay to lease them according to the businesses usage. Cloud resources are a virtual form of storage, meaning companies comfortably use them without the trouble of systemic dependencies or constraints. Businesses are finding that cloud computing can be scaled dynamically

A significant paradigm shift is represented by public cloud computing from conventional norms of an organizational data center to a de-parameterized infrastructure which opens gates for potential adversaries to use. Cloud computing should be approached carefully with any emerging information technology area with due consideration to the sensitivity of data. A good planning helps and ensures that the computing environment is secure to the most possible extant and is in compliance with all relevant policies of an organization and makes sure the privacy is maintained.

A lot has being said concerning issues surrounding the law and cloud computing. Some of these issues include privacy and data security concerns and laws and regulations. Regardless of what cloud computing models an organization uses, both the cloud provider and the consumer ha to operate under this laws. Therefore both parties need to have a broad knowledge of the these laws such as data breaches, information ownership and control and how close customers can manage risk both at the federal and state levels.

Cloud computing is able to offer a distinct advantage to companies willing to move into this growing arena. This is not without its drawbacks. Even in the definition of Cloud Computing by the National Institute of Standards and Technology, (NIST) clear advantages exist. The definition includes the following terms: on demand self-service, ubiquitous network access, location independent resource pooling, rapid elasticity and measured service.

The purpose of the article is to provide a brief summary of cloud computing, a relatively new concept that has emerged with the increasing use of technology. In describing cloud computing, the article also informs the general public of its limited privacy and security levels, one of the main issues currently surrounding cloud computing. The article evaluates existing laws governing the privacy and security of the information and data of individuals, prompting readers to be more cautious in their use of the cloud.

It would be fair to say that cloud computing has changed the way the business used to do. With the evolution of cloud computing, IT companies can get software to hardware and infrastructure to staff requirement on demand. Cloud service providers also fully mange the services which can be provided at any time. Cloud computing utilizes a combination of the internet (cloud) and computer technology (computing). It is broadly defined as methods to deliver information or services to customers who pay for what they use. It uses the architecture in which one provider is giving services to multiple organizations. This paper, I will be discussing about risk and challenges of cloud computing. My main focus on the paper will be over cloud, its standardization, challenges/concerns and current business transformation.

Cloud technology links remote computers to a network of data servers that contain user data. It serves to increase efficiency in data access, increase user convenience and lower costs. It also has created efficiencies in terms of user hardware requirements necessary to access files and programs in multiple locations. A system designed in only 2006, it has already become a $68 billion global industry, with an anticipated $17 billion per annum growth rate. With such a growth rate, cloud technology is rapidly becoming an increasingly important aspect of individual and corporate data storage. While cloud technology provides an expansive range of possibilities of use for individuals and businesses alike, it has also posed challenges for its effective governance and privacy.

Cloud computing is the result of evolution and adoption of existing technologies and prototypes; although the origin of the term cloud computing is unclear. In the earliest stages, the term ‘cloud’ was used to represent the computing space between the provider and the end user. References to cloud computing in its modern sense appeared as early as 1996, with the earliest known mention in a Compaq internal document (Regalado, 2011). In 1997, Professor Ramnath Chellapa of Emory University and the University of South California defined cloud computing as the new “computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits alone”. This has become the basis of what we refer to today when we discuss

The customers of cloud services are anxious about the security and confidentiality of their sensitive client data. This fear is

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)

This project is going to discuss about the Cloud Computing and its application in business. To briefly describe what cloud

Over the past decade, a commoditization and standardization of technologies, virtualization and the rise of service-oriented software architectures along with the dramatic growth in the adoption of the Internet has resulted in a discontinuity that amounts to a new opportunity to shape the relationship between those who use IT services and those who sell them. This has led to an evolution from legacy, hardware-oriented datacenters, through adoption of virtualization to private cloud infrastructures. The trend toward cloud computing started in the late 1980s with the concepts of grid computing when, for the first time, a large number of systems were applied to a single problem, usually scientific. In the 1990s the concept of virtualization was expanded beyond virtual servers to higher levels of abstraction,
