...White Paper Cloud Computing in Higher Education: A Guide to Evaluation and Adoption Executive Summary Public cloud computing—delivering infrastructure, services, and software on demand through the network—offers attractive advantages to higher education. For example, it has the potential to reduce information and communications technology (IT) costs by virtualizing capital assets such as disk storage and processing cycles into a readily available, affordable operating expense. Sometimes selecting a public cloud offering can create risk around security, privacy, interoperability, or performance. When it does, universities should consider private cloud deployment models to realize scale on demand, rapid platform deployment, and lower costs and carbon emissions while minimizing risk. Introduction The cloud-computing market is projected to grow from $40.7B in 2011 to $240B in 2020 (“Sizing the Cloud” by Stefan Ried and Holger Kisker, Forrester Research, April 21, 2011). , Such rapid market growth is a clarion call to all chief information officers (CIOs) to explore the possibilities offered by cloud and to assess the risks. Most are familiar with the cloud concept because many already use some aspect of cloud applications—software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS); for example, Google’s Gmail, iTunes University, and Amazon’s infrastructure, respectively. The cloud space is rapidly adopting a plethora of new acronyms...

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...

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...

...Cloud Computing Group Members Ruth Wanjiru Cliff Kinyua Maritim Leonard Alphonse Kinyua Tracy Gathoni Abstract. 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. History: The origin of the term “cloud computing” is nebulous. The term only gained traction around 2006 or 2007, but we found references dating back from much earlier [7] The idea of an "intergalactic computer network" was introduced in the sixties by J.C.R. Licklider, who was responsible for enabling the development of ARPANET (Advanced Research Projects Agency Network) in 1969. John McCarthy proposed the idea of computation being delivered as a public utility, similar to the service bureaus which date back to the sixties. Since the sixties, cloud computing has developed along a number of lines, with Web 2.0 being the most recent evolution. Salesforce.com in 1999 pioneered the concept of delivering applications via a simple website...

...Cloud computing Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation. There are many types of public cloud computing:[1] Infrastructure as a service (IaaS) Platform as a service (PaaS) Software as a service (SaaS) Storage as a service (STaaS) Security as a service (SECaaS) Data as a service (DaaS) Database as a service (DBaaS) Test environment as a service (TEaaS) Desktop virtualization API as a service (APIaaS) Backend as a service (BaaS) In the business model using software as a service, users are provided access to application software and databases. The cloud providers manage the infrastructure and platforms on which the applications run. SaaS is sometimes referred to as “on-demand software” and is usually priced on a pay-per-use basis. Saas providers generally price applications using a subscription fee. Proponents claim that the SaaS allows a business the potential to reduce IT operational costs by outsourcing hardware and software maintenance and support to the cloud provider. This will enable a business to reallocate IT operations to focus on other IT goals. In addition, the application is hosted centrally, so updates can be released without users...

...CLOUD COMPUTING – An Overview Abstract Resource sharing in a pure plug and play model that dramatically simplifies infrastructure planning is the promise of „cloud computing‟. The two key advantages of this model are easeof-use and cost-effectiveness. Though there remain questions on aspects such as security and vendor lock-in, the benefits this model offers are many. This paper explores some of the basics of cloud computing with the aim of introducing aspects such as: Realities and risks of the model Components in the model Characteristics and Usage of the model The paper aims to provide a means of understanding the model and exploring options available for complementing your technology and infrastructure needs. An Overview Cloud computing is a computing paradigm, where a large pool of systems are connected in private or public networks, to provide dynamically scalable infrastructure for application, data and file storage. With the advent of this technology, the cost of computation, application hosting, content storage and delivery is reduced significantly. Cloud computing is a practical approach to experience direct cost benefits and it has the potential to transform a data center from a capital-intensive set up to a variable priced environment. The idea of cloud computing is based on a very fundamental principal of „reusability of IT capabilities'. The difference that cloud computing brings compared to traditional concepts of “grid computing”, “distributed computing”, “utility...

...Cloud Computing Kevin Chang Chantal O’Connor Tameika Lee Richard Roberts Information Technology – INT1001 Lecturer: Lushane Jones University of Technology, Jamaica 4th November 2010 ABSTRACT This paper discusses what is meant by the term cloud computing, the difference between private and public cloud computing, the benefits and challenges that are being derived from adopting cloud computing and how it will change the way we work. It cites examples of enterprises that have adopted the concept, stating the success or lack thereof. It also discusses the possible future of cloud computing. WHAT IS CLOUD COMPUTING? Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that is often used to represent the Internet in flowcharts and diagrams. See Figure 1. A visual representation of the Cloud including some companies that offer cloud based services. A cloud service has three individual characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour. It is elastic, a user can have as much or as little of a service as they want at any given time and the service are fully managed by the provider (the consumer needs nothing...
