...The Future of Cloud Computing Melissa Gilchrist INF 103: Introduction to Digital Literacy Brent Ferns March 3, 2014 The Future of Cloud Computing Cloud computing is defined as being a replacement of all computers with “dumb” terminals that have no software or complex operating systems on them (Bowles 2013). This means that applications and the data used are being housed online rather than being put on your computer. As Americans these days we at some point are already using some of the cloud applications. With the future of technology rising in this day and age some wonder what the future actually holds for cloud computing and just how it will play a major role in society. After reading my textbook and the two scholarly articles I chose for my research paper, they all discussed the importance of cloud computing in the future and its advantages. This will have a large impact on technology and the use of computers. One advantage of cloud computing discussed in the course material Introduction to Digital Literacy (Bowles 2013) was the start-up time of the actual cloud. Software companies such as Google are now building operating systems that exist on-line rather than on your computer you use. This means that there would be non complex systems to boot up the computer. You would only have to press the power button and in seconds you will be connected to the internet as long as you have an internet connection. Another advantage would be the fact that computer...

...EBM510 - Information Processing and the Web Cloud Computing Research Paper Mahesh BahuleyanNair 000-14-6974 Abstract This research paper is to recommend or suggest cloud computing as an alternative to the obsolete and highly expensive traditional computing mechanisms. Cloud computing is a new general purpose Internet-based technology through which information is stored in servers and provided as a service and on-demand to clients. Cloud computing services including Infrastructure as a Service promise potential cost savings for businesses by offering remote, scalable computing resources. However attractive these services are, they pose significant security risks to customer applications and data beyond what is expected using traditional on-premises architecture. This paper identifies three basic types of threats related to the IaaS layer and eight kinds of attacks. These are aligned within the CIA model as a way to determine security risk. Cloud computing is a generalized term for anything that involves delivering hosted services over the Internet. These services are broadly divided into threesome categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The study darken computing was inspired by the darken symbol that's often utilized to equal the Internet in flowcharts and diagrams. A darken assist has threesome...

...[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...

...Mobile Cloud Computing (MCC): A Survey Abstract: Mobile devices have come a long way and their capabilities in terms of speed, raw computing capabilities, storage capacity and the applications that are real world end user friendly. The sale of mobile devices has seen a huge boom and is now surpassing those of PCs [1]. With this enormous use of smart phones across the world and as well as the introduction of cloud computing concept, Mobile Cloud computing or MCC has become the new paradigm in the world of mobile services. This paper will discuss the technology of MCC, applications and challenges faced. Mobile Cloud Computing: Introduction MCC in its simplest form can be defined as an infrastructure where the storage of data and its processing is outside a mobile device. What mobile cloud computing does is move processing and storage to the cloud and thereby bringing applications and the computing power to a broader spectrum of mobile users [2]. Mobile service providers can provide services to the subscribers as AAA which refers to authentication, authorization and as well as accounting which is based on what is known as an home agent or HA and the end users data being stored on the cloud database. Every time a request is initiated from the subscriber, it is delivered to the cloud based system with the help of Internet. The controllers on the cloud will be able to process these requests and eventually providing the subscribers with the respective cloud based service. These...

...An Introduction to Cloud Computing UKOLN: Supporting The Cultural Heritage Sector What is Cloud Computing? Cloud computing is an umbrella term used to refer to Internet based development and services. The cloud is a metaphor for the Internet. A number of characteristics define cloud data, applications services and infrastructure: • Remotely hosted: Services or data are hosted on someone else’s infrastructure. • Ubiquitous: Services or data are available from anywhere. • Commodified: The result is a utility computing model similar to traditional that of traditional utilities, like gas and electricity. You pay for what you would like. Software as a Service (SaaS) SaaS is a model of software deployment where an application is hosted as a service provided to customers across the Internet. SaaS is generally used to refer to business software rather than consumer software, which falls under Web 2.0. By removing the need to install and run an application on a user’s own computer it is seen as a way for businesses to get the same benefits as commercial software with smaller cost outlay. Saas also alleviates the burden of software maintenance and support but users relinquish control over software versions and requirements. The other terms that are used in this sphere include Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Cloud Storage Several large Web companies (such as Amazon and Google) are now exploiting the fact that they have...

...Cloud Computing: A Brief Introduction The origin of the term cloud computing is obscure, but it appears to derive from the practice of using drawings of stylized clouds to denote networks in diagrams of computing and communications systems. The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network on telephony schematics and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. In the 1990s, telecommunications companies who previously offered primarily dedicated point-to-point data circuits, began offering virtual private network (VPN) services with comparable quality of service but at a much lower cost. By switching traffic to balance utilization as they saw fit, they were able to utilize their overall network bandwidth more effectively. The cloud symbol was used to denote the demarcation point between that which was the responsibility of the provider and that which was the responsibility of the users. Cloud computing extends this boundary to cover servers as well as the network infrastructure.[10] The underlying concept of cloud computing dates back to the 1950s; when large-scale mainframe became available in academia and corporations, accessible via thin clients / terminal computers. Because it was costly to buy a mainframe, it became important to find ways to get the greatest return on the investment in them, allowing multiple users...
