...Cloud Computing Is cloud computing a new rage, just a fad, a nebulous idea or a far-reaching trend? Cloud computing has become a buzz word in working and learning environments around the globe. Newsstands and Internet pages everywhere are inundated with articles, whitepapers and websites dedicated to defining the many facets of cloud computing such as hosting a website on the cloud, building a cloud infrastructure, cloud security, vulnerabilities, capabilities, pros and cons and cost. IEEE.org (IEEE CLOUD COMPUTING) has dedicated pages on their website to reference nothing but articles of interest and white papers surrounding cloud computing. The barrage of information can be daunting. Jon Oltsik (Oltsik) eloquently discusses industries’ bewilderment with cloud computing when he writes: When discussing cloud computing, I often think of Joni Mitchell's haunting lyrics from the song,Both Sides Now (jonimitchell.com). In Mitchell's world, clouds can be wonderful "ice cream castles in the air" or annoying disturbances that "only block the sun." This duality prompts Mitchell to declare, "It's clouds illusions I recall, I really don't know clouds at all." Joni's cloud confusion mirrors current industry bewilderment over cloud computing. Like many other industry initiatives, cloud computing has a number of meanings. Finally, industry confusion is no more. A guideline has been prepared by the National Institute of Standards and Technology (NIST). NIST is responsible...

...Cloud Based Computing By: Alex Hornberger Introduction Cloud based computing is a new and very misunderstand piece of technology. Businesses moving their IT services to the “Cloud” will cut expenses and increase productivity. In this report I will discuss what cloud based computing is, how it can benefit and business. To better understand what cloud computing is, the key components must be understand first. When referring to the cloud, that is nothing more than the internet. The internet is a logical place hosted on physical hardware. (Ricadela,2007) Cloud computers are multiple PC’s housed on a single piece of hardware. This allows a company to get the most out of their IT investment. Instead of running one single operating system on a piece of hardware, it gives the ability to run multiple logical PC’s on a single piece of hardware simultaneously. This is important due to the amount of money that can be saved by a business, PCs costs any were from $300 dollars to $2000 dollars. To begin to utilizing cloud computing a business has to purchase a mid to high end server which will house all of the virtual machines. Each virtual machine will only use the designated amount of resources, this gives an administrator the ability to assign resources as needed. Challenges There are many challenges facing a business to adopted the Cloud Computing. One challenge is understanding the way it functions and works, most business owners chose not to get involved in how their...

...constant rotations and deployments, and the Operations and Maintenance (O & M) contractors, who have the knowledge base and the continuity but are on edge due to contract issues and tenuous job security. Added to that tumultuous mix is my small contract of twelve people who are implementing a methodology of best practices for managing a complex Information Technology (IT) organization. This methodology, known as IT Infrastructure Library (ITIL), provides a framework of processes that give shape and order to an IT operation. These three teams, the military, the O & M contractors, and the ITIL improvement team work together to provide network services for the greater Air Force, striving to maintain network availability while keeping the data secure from intrusion or compromise. 2. Problem Statement In the last four or five years collaborative computing and social networking have rapidly increased both in the business environment and in people’s personal lives. On the home front, the internet sites Facebook, MySpace, YouTube, and Twitter have seen phenomenal growth: In 2009 the user growth rate on Facebook was 145% (Corbett, 2010), and other social media sites have shown similar growth rates (Owyang, 2010). In business and of late in the military, collaborative tools that allow users to chat from their desktops, collaborate on documents, and hold...

...economics works with cloud computing. Is economics the way to go with cloud computing? What is the general understanding of economics when it comes to cloud computing? How will businesses benefit from cloud computing? Will cloud computing work within a budget of an organization? Businesses will economically grow and benefit with cloud computing. Cloud computing has significant implications for the way companies, businesses, and governments access and use information technology. It enables users to remotely access scalable, high-powered computing services via broadband networks from a range of devices, all on-demand. Cloud computing has the potential to provide users with increased computing capability, greater efficiency, and lower energy and infrastructure costs. According to Kevin Jackson of Forbes.com he describes cloud computing as a metrics. According to Kevin Jackson the four sets of cloud computing economics are the number of unique customer sets, customer set duty cycles, relative duty cycle displacement and customer set load. These metrics reduce resources and creates more resource demand. According to Mr. Jackson of Forbes.com this “properly balancing these factors across a well characterized user group can lead to approximately 30-percent savings in IT resources, and enables the near real-time modification of the underlying physical infrastructure required for the delivery of the desired “illusion of infinite resources” synonymous with a cloud computing user’s...

...The concerns of ethics and computer is a constant balancing act. Technology will continue to advance and it’s our job to make sure that we always keep ourselves and our neighbors in mind when it comes to ethical behavior and computer technology. In this paper three article that touch on ethical concerns in computing in their own way. One will discuss how the concerns that we all may be very easily find ourselves in on a daily basis. One will look into more specific areas where ethics and computers intertwine, using cell phones to track pedestrians and home monitoring for the elderly. The other will hit on the risk and rewards of cloud computing and the ethics behind law firms and their move into the 21st century. Ethics surrounding computer technology are currently an ever evolving conversation. As technology advance so must the ethics and rules of how we handle our personal information and how others can and cannot used that information. With this evolution in technology there are many topics of concern that raise red flags and force people to reevaluate what needs to change in order to make sure that the very principals we hold as a country are not bent to meet the demands of changing technologies. Concerns over personal and private data who can see what and at what point is personal data no longer private. Identity theft is another issue as people become more and more willing to use computers to bank and pay bills they are more at risk of another person electronically stealing...

...Security is a main concern with VoIP, as it is with other Internet technologies. The most prominent security issues over VoIP are identity and service theft, viruses and malware, denial of service, spamming, call tampering and phishing attacks. Analysis of Cloud Computing In a cloud computing system, there's a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demands on the user's side decrease. The only thing the user's computer needs to be able to run is the cloud computing systems interface software, which can be as simple as a Web browser, and the cloud's network takes care of the rest. There's a good chance you've already used some form of cloud computing. If you have an e-mail account with a Web-based e-mail service like Hotmail, Yahoo Mail or Gmail, then you've had some experience with cloud computing. Instead of running an e-mail program on your computer, you log in to a Web e-mail account remotely. The software and storage for your account doesn't exist on your computer, it's on the service's computer cloud. When talking about a cloud computing system, it's helpful to divide it into two sections: the front end and the back end. They connect to each other through a network, usually the Internet. The front end is the side the computer user, or client, sees. The back end is the "cloud" section of the...

...Section IV presents the models developed to represent a mobile cloud system. A case study is described in Section V, with the results obtained through model analysis. Section VI concludes the paper, presenting also some possible future works. II. BACKGROUND Abstract—Mobile cloud computing refers to abstraction of computational power to outside of the mobile device, processed in the “clouds”. This paper provides an availability and energy consumption study using hierarchical heterogeneous modeling. Different scenarios were analyzed considering wireless communication technologies, such as 3G and WiFi. The results shows that the 3G protocol causes a lower availability and is the greater responsible for the discharge of battery, but when is combined with WiFi protocol providing communication redundancy, we have the best results of availability and better results of uninterrupted operation time of battery. I. I NTRODUCTION In the last years, the tech industry has showed a special interest in cloud computing and mobile devices. Cloud computing enables the use of computing resources by means of providers that may be in any geographic location, accessible through de Internet, i.e., in the clouds [1]. In parallel with the advance of cloud computing, mobile phones have evolved from...

...Title: IBM and The Emerging Cloud-Computing Industry Case Study Analysis Introduction The character of a company -- the stamp it puts on its products, services and the marketplace -is shaped and defined over time. It evolves. It deepens. It is expressed in an ever-changing corporate culture, in transformational strategies, and in new and compelling offerings for customers. Those are the words that start the chronological history on the IBM website [1]. I couldn’t agree anymore with that statement. I am often very fascinated by the evolvement of technology stories I get to hear quiet often from my fellow senior coworkers. One of the stories I enjoy is about the large IBM370 computer my workplace once owned in 1970’s. From my understanding it occupied a whole room and it required several people to operate. That was less than a half century ago. Today the smart phone’s memory is much higher than that computer. For my time what I could relate to, is the floppy disk which of course is obsolete today. I am sure my kids will be fascinated by the floppy disk someday just like I get fascinated by circular slide rule that predated the calculator era. In place of floppy disks or another external memory, in the cyber world today, cloud computing is taking place of all those external memories. IBM website defines Cloud computing as, the delivery of on-demand computing resources everything from applications to data centers over the Internet on a pay-for-use basis [1]. Background...

...[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...

...Cloud Computing: The Benefits and the Downside Air, energy, the environment are intangible to the human eye, but yet all three play an integral part in our survival. Cloud computing relates to these three things because all of these could be adversely affected by cloud computing. Technology is an ever evolving and growing market dominated by the consumerism of Apple products and a world where instant gratification is gloried as information is processed in the matter of seconds. The evolution of technology has not only changed the way that we communicate with one another, but also the way in which businesses must conduct their daily transactions. A person in the United States can keep in touch with a friend thousands of miles of way in Brazil or England using Facebook or Twitter. World events spread in the same manner as wildfire, uniting citizens around the world with such topics as war and human rights. We live in a society in which technology has shaped the people that we are today. Most students in middle or high school have had access to a cellular phone since their birth. Beyond the surface of technology being used as a device to interact with one another, technology is used as a device to store information. Our society has transformed from storing information on a hard drive or a flash drive to the information being stored on the Internet via the concept of cloud computing. Cloud computing is the act in which information can be stored and reviewed over the Internet rather...
