CLOUD COMPUTING is the latest buzz in technology and business, which experts believe has the power to reshape IT). This paper seeks to define the concept and its features, how it could be used at the company I work, the implications and recommendations to overcome any challenges that could be encountered. CLOUD COMPUTING is a model in which literally all resources and services – development tools, application software, data storage, processing power and back-up facilities – are sold via the internet (Aljabre, 2012). Simply explained, it is a technology that is used to acloud computingess different services on the internet or ‘cloud’. It offers flexible payment plans and leases (Kroenke (2007, p. 125) on a monthly or yearly basis (Furht & Escalante, 2010), and as well as per-per-use facility (Hunsberger & Gale, 2011). It has five layers, but here, I will only mention three. The first called “software as a service” (SaaS), which lets users run applications from a browser remotely from the cloud, e.g.salesforce.com (Furht & Escalante, 2010). The second layer is called “platform as a service” (PaaS), with an operating system in the cloud (The Economist, 2010). With PaaS, functions like spam filtering and archiving are added from the cloud on exchange servers on the clients’ premises, via Microsoft exchange hosted services (Furht & Escalante, 2010). Infrastructure as a service” (IaaS), offers basic computer services, including processing power and storage (The Economist, 2010). IaaS is usually used by developers to create applications (Furht & Escalante, 2010). There are three types of CLOUD COMPUTING: 1) public cloud – computer services are externally supplied over the internet via web applications from an off-site third party provider; 2) private cloud – which is exclusively built and managed by a company’s own IT unit or cloud provider; and 3) hybrid cloud, which is…...

...How Cloud Computing Improve Resource Management Hajar Bte Ahmedy Master of Business Administration: Faculty of Business Management BM 7702CF UiTM Shah Alam hajarahmedy@gmail.com Abstract— The emergence of cloud computing has changed the perception of how a resource management can be properly managed. Cloud computing is crucial in resource management. Without the improper implementation of cloud computing, applications or CPU might experience network congestion, long time wait, waist in CPU, overused CPU and memory, and security problems. In order for the resource management properly maintain, a good usage of cloud computing infrastructure utilization needs to be maximized. Keywords-component; Resource Management, Cloud Computing, Types of cloud computing Introduction The emergence of cloud computing has changed the perception of how a resource management can be properly managed. Cloud computing has been integrated with the business processes and it refers to the applications and services offered over the internet. These services are offered from data centers all over the world, which are collectively referred to as the “cloud”. The idea of cloud can be represent many network connections and computer systems involved in online services. It shows that the cloud computing is crucial in a resource management. On the other side, many network diagrams use the image of cloud computing to represent the internet. It can actually represent the internet’s broad...

...Cloud Computing ABSTRACT Cloud computing is Internet- ("cloud-") based development and use of computer technology ("computing"). In concept, it is a paradigm shift whereby details are abstracted from the users who no longer need knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them. Cloud computing describes a new supplement, consumption and delivery model for IT services based on Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet. The term cloud is used as a metaphor for the Internet, based on the cloud drawing used to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. Typical cloud computing providers deliver common business applications online which are accessed from a web browser, while the software and data are stored on servers. These applications are broadly divided into the following categories: Software as a Service (SaaS), Utility Computing, Web Services, Platform as a Service (PaaS), Managed Service Providers (MSP), Service Commerce, and Internet Integration. The name cloud computing was inspired by the cloud symbol that is often used to represent the Internet in flow charts and diagrams. THE CLOUD COMPUTING AN...

... 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...

...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...

Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallels to this concept can be drawn with the electricity grid, where end-users consume power without needing to understand the component devices or infrastructure required to provide the service. Cloud computing describes a new supplement, consumption, and delivery model for IT services based on Internet protocols, and it typically involves provisioning of dynamically scalable and often virtualized resources It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.

...CLOUD COMPUTING FOR EDUCATION Introduction Over the past few years, people have become increasingly accustomed to the “always on” Internet, and we expect our devices to be connected all (or at least most) of the time. You should be able to pop open a browser any time you like and have access to information anywhere in the world. You also need email applications to fetch new mail for you whenever it is available, without you having to manually log on somewhere to get it. Other applications, such as RSS feed readers, instant messaging clients, and so on also get information from the Internet in the same way. These are examples of using web services to communicate with other applications that exist somewhere on the Internet. Web services allow you to send and receive information. A cloud is a combination of hardware, networks, storage, services, and interfaces that helps in delivering computing as a service. It has broadly three users, which are end user, business management user, and cloud service provider. The end user is the one who uses the services provided by the cloud. The business management user in the cloud takes the responsibility of the data and the services provided by the cloud. The cloud service provider is the one who takes care or is responsible for the maintenance of the IT assets of the cloud. The cloud acts as a common center for its users to fulfill their computing needs. Cloud Computing

...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...

...[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...

...Cloud Computing Abstract: In this fast computerized world, cloud computing is one of the emerging technology in today's life and plays a major key role in changing the aspects of the computer world as many organizations have started using it from day to day life. The main purpose of "The Cloud" is what kind of models/architectures it offers for research and development in this digital world. Cloud computing primarily focuses on sharing data over a scalable network. The network includes data centers, end user computers and web services. Such a network of nodes is called cloud. An application based on such cloud is called cloud application. Usually, cloud is an image for internet which uses the existing infrastructure to access services regardless of location and time. Before we discuss the service models, the cloud computing can be broadly classified into two categories namely: 1) Cloud Applications: These are accessed by users via Internet as they run on a shared data center. Example: Google apps 2) Cloud Platforms: These are used by developers for supporting cloud applications, run applications, store data and other important services. Example: Amazon Web Services Cloud computing environment has three core options which are as follows: SaaS (Software as a Service): It consist of end-user applications. The most commonly used example is Sales force which provides a customer relationship management. PaaS (Platform as a Service): It provides an application platform...

..."Cloud Computing:Taking the world by storm" (Cloud computing is becoming very popular around the world. A storm (Internet) comes in quickly and with power) What is cloud? Where is cloud? Are we in the cloud now? These are some of the questions we've probably heard or even asked ourselves. The term "cloud computing"is everywhere. Cloud computing has received a lot of popularity anywhere. It is well known for being the storage solutions to provide individuals and enterprises with various capabilities in storing and processing their data. Cloud computing also known as cloud manage, store and process relevant data. It's cheaper, faster and easy to maintain because not only businesses but regular Internet users can also use cloud computing services such as Google Docs, EFAX,YouTube, Webex, YouSendIt, Gliffy, Yahoo, Mozy, LinkedIn,Picnik, Zamzar, PBWiki, Blogger and Dropbox. With the use of cloud we can access a data or search informations whenever and wherever we are, as long as we have internet connection. Instead of using personal computer of a local server or your computer's hard drive why not store it at the cloud? Here are some key points, advantages, importance and disadvantages you need to know about cloud computing: • There are two versions of cloud computing. Two of the more popular versions of cloud offerings are Software-as-a-Service also known as SaaS and Infrastructure-as-a-Service also known as laaS. • With SaaS, the cloud service provider hosts your...

...In this research paper, I will discuss the following topics about Cloud computing, the several cloud deployment and service models. This paper will cover the benefits and disadvantages of cloud computing over the traditional IT environment including scalability, flexibility, security, and privacy. Now a days cloud computing is considered the next big thing, a tool that is used by marketers to be impressive, for example Microsoft release a commercial back in 2010 with a man in front of a computer and then an image saying “Into the Cloud” (youtube.com). This tool is being used by many companies to attract customers yet many people fail to understand what Cloud computing is, Cloud computing is an overall philosophy and design concept that is much more complex and yet simpler then people give it credit for. Cloud Computing is a new term to many people since it was introduced to the general public in 2006 (infoworld.com). However it has been around for much longer, Western Union was thought to have created the term “The Cloud” in the 1960`s (infoworld.com). Those who have been in the business for a long time like David S. Linthicum who is a consultant at Cloud Technology Partners, and is an internationally recognized industry expert who has authored 13 books on cloud computing can recall the name “The Cloud” in the 1980`s in terms of networking semantics (infoworld.com).The term Cloud Computing itself has changed over the years and is still evolving to this day.

...Professor Danner ISYS 263 October 18, 2015 Cloud Computing Cloud computing is a cost effective and on-demand way to access data from servers, storages, databases, and applications over the internet as a service. The uses from cloud computing includes not only software as a service (SaaS), but also platform as a service (PaaS), and infrastructure as a service (IaaS). Cloud Computing has many advantages for everyday users of the internet through applications, such as Facebook or Google drive, to more intricate uses for businesses, such as outsourcing data and business applications. Cloud computing allows online applications to let their users access the application without the need of having to install, update, or manage the application. Also businesses use cloud computing as a way for cost- savings and more efficient processing by outsourcing their huge collections of data utilizing complex information systems. The main advantages of cloud computing are that it allows for easy storage and scalability, better processing, cost efficiency, backup recovery, and mobility. Companies dodge not having to create their own infrastructure of servers, not having to update and manage software or applications, not having to hire and train staff, and would even have decreased onsite energy cost. The powerful servers contained by the third party also allows for a more efficient processing, which is easier for the third party to do because their company is dedicated to effective...
