public cloud computing services

“The agility, cost savings and fast response times of public cloud services can afford financial enterprises huge business opportunities”,says Stephen Schmidt, vice-president and chief information security officer of Amazon Web Services (AWS).As is becoming more and more known to us,public cloud computing services promises to play an important part in our society. A cloud is called a "public cloud" when the services are rendered over a network that is open for public use. A public cloud is a set of computers and computer network resources based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet[1] . Public cloud services may be free or offered on a pay-per-usage model.In the public cloud, your network resources and IT expenses are shared among users – resulting in lower costs, while allowing for total elasticity. For instance, if your network calls for more resources one month, while less the next, scaling your network to match is as simple as flipping a switch.Technically there may be little or no difference between public and private cloud architecture, however, security consideration may be substantially different for services (applications, storage, and other resources) that are made available by a service provider for a public audience and when communication is effected over a non-trusted network. Generally, public cloud service providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access only via Internet. Public clouds are the latest evolution of computing, offering tremendous value to businesses in terms of better economics, agility, rapid elasticity, etc. The public cloud infrastructure is operated by a cloud service provider and the services are offered…...

...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...

...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......

... 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......

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.

Cloud Computing

...[pic] Cloud computing in general isn’t a term that can be defined with one specific definition as different people from all over the world each have a different understanding of the term cloud computing. Hence the best way to effectively explain the term is to explain it using different examples. Some people believe the term to mean another way of describing IT (information technology), others use it to mean any computing service provided over the Internet or a similar network; and some define it as any bought-in computer service you use that sits outside your firewall. As you can seem, there is no straightforward definition for the term and therefore best way to understand it is to learn about how it works. The main point of cloud computing can be summed up with this one short sentence: “Access your data anytime and anywhere” What is the difference between cloud computing and old fashioned personal computing? An important thing that differentiates cloud computing to the now old fashioned and declining personal computing is the location where all the data is stored. In cloud computing the data is stored on a remote database operated by a third party which can be accessed from most places, as the main requirement to access this cloud storage is only an Internet connection. In personal computing, all data is stored on a hard drive or another form of data storage device such as a usb drive, and once the data storage limit is reached a bigger hard drive...

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.
