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 but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with Internet

...[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 Introduction This term paper will describe the characteristics of Cloud Computing and services associated with it. It will cover how businesses deploy services such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), as well as some of the benefits and challenges of Cloud Computing. Cloud Computing Definition - Cloud Computing is basically servers providing specific services to businesses and individuals over the internet. Characteristics * Shared Infrastructure — is when data centers use virtualization software on existing servers. This cuts down on total cost of infrastructure, storage, and networking bandwidth. * Dynamic Provisioning —Server computing instances or virtual machines are provisioned dynamically from a centralized console using automated software. The amount of services provided are determined by current demand requirements. * Network Access — One thing I like about Cloud Computing is the ability to access your account from anywhere, from any device. As long as you have an internet connection, you can use your pc, tablet, laptop, or mobile devices. An example is using iCloud storage to backup and restore your iphone. * Managed Metering — Another thing I like about Cloud Computing is you are only billed for what you use. Metering is used to optimize the service, provide reporting, and billing information. Service Models Once a cloud is established, how...

In this work we strive to frame the full space of cloud-computing security issues, attempting to separate justified concerns from possible over-reactions. We examine contemporary and historical perspectives from industry, academia, government, and “black hats”. We argue that few cloud computing security issues are fundamentally new or fundamentally intractable; often what appears “new” is so only relative to “traditional” computing of the past several...

...Cloud Computing Cloud computing is being hailed as an important technological shift which promises to change the face of information technology and data management in not only unprecedented ways but also in ways which are yet to be conceived. In other words, cloud computing is believed to offer a world of limitless potential and opportunity which may transform the ways in which businesses handle, store, access and manage data and the ways in which they deploy the necessary hardware, software and liveware assets for achieving their organizational goals. Cloud computing refers to the capability to deliver computing as a service, be it raw computing power, generic or specialized software, or storage space. This delivery is done through an interconnected network of computers to users who pay for the respective services as per their use. The reason that these services are known as ‘cloud’ is that the users typically do not know the exact location of their data / programs (all they know is that it is somewhere ‘out there’, or ‘on a cloud’). Status Quo - On-Premises Traditionally, most of the computing structures of the business organizations were designed as on in-premises systems. This comprised arrays of servers (number, size and power depending upon the size and computational requirements of the respective organizations), software (generic as well as customized) installed on those same servers and / or workstations, and storage capacity housed in the same place (usually)...

...To: Mari Buche, Colleague From: Kristen Therrian, Colleague Date: October 20, 2014 Subject: Cloud Computing The world of cloud computing has recently become of interest in my research. I would like to hear from you on whether cloud computing is something I should pursue after discussing what cloud computing is, what is the cloud computing system architecture like, what are its advantages, and disadvantages. The article reviewed shows that cloud computing is a network of computers that handles the brunt work of running applications. Companies need only to install one application that lets employees log onto a web-based service, such as the internet which hosts all the programs that users would need. The interface software which is like a browser, is the only thing that is needed. The network of the cloud will take care of everything else. The cloud architecture has a back end and a front end. The back end allows users to connect to the internet or network. It is also where numerous servers, computers, and storage systems are located that build the “cloud” of the computing system (Strickland, 1998-2014). The front end is what the user can view and it is where the client’s computer and the application that is the means of entry to the cloud system is located. It is important to note that each application acquires its own server. The central server manages the system where it audits traffic and demands of clients to guarantee everything runs properly. The central server...

...Cloud computing is now evolving like never before, with companies of all shapes and sizes adapting to this new technology. Industry experts believe that this trend will only continue to grow and develop even further in the coming few years. While cloud computing is undoubtedly beneficial for mid-size to large companies, it is not without its downsides, especially for smaller businesses. We now bring you a list of advantages of disadvantages of cloud computing, with a view to helping such establishments fully understand the concept of cloud computing. Saas, Paas and IaaS in the Mobile Industry Advantages of Cloud Computing If used properly and to the extent necessary, working with data in the cloud can vastly benefit all types of businesses. Mentioned below are some of the advantages of this technology: Why Cloud Computing Is Ideal for Small Businesses Cost Efficient Cloud computing is probably the most cost efficient method to use, maintain and upgrade. Traditional desktop software costs companies a lot in terms of finance. Adding up the licensing fees for multiple users can prove to be very expensive for the establishment concerned. The cloud, on the other hand, is available at much cheaper rates and hence, can significantly lower the company’s IT expenses. Besides, there are many one-time-payment, pay-as-you-go and other scalable options available, which makes it very reasonable for the company in question.

...The power of cloud You can hardly look at an IT strategy document today without seeing mention of cloud computing, even though it has been around for years. This model has now crossed the chasm to penetrate corporate America, which traditionally relied on internal infrastructure. This is a significant shift in IT mindset in what will certainly be remembered as a disruptive technology strategy that changed the way the world works, literally. What is cloud? Cloud computing is a pay-per-use consumption and delivery model that enables real-time delivery of configurable computing resources (for example, networks, servers, storage, applications, services). Typically, these are highly scalable resources delivered over the Internet to multiple companies, which pay only for what they use. Cloud delivery models can help organizations scale their investments as they grow their business. They can also open the door to new business approaches through standardized applications, infrastructure, testing environments and business processes that help improve service delivery and efficiency. Although cloud is widely recognized as a technology game changer, its potential for driving business innovation remains virtually untapped. Indeed, cloud has the power to fundamentally shift competitive landscapes by providing a new platform for creating and delivering business value. To take advantage of cloud’s potential to transform internal operations, customer relationships and industry value chains...

...Introduction What is cloud computing? To explain, it is kind of hard to explain as it is more like technology thing which only IT peoples know well. Assume you have run a big corporation; your responsibility is to make sure your employees have the right hardware and software to do their job. But, purchasing computer is not enough as you need to purchase software license give employees the right tools. This will cost a lot and eventually lost profit. Instead for each computer install the software, you just have to load one application only. That application would allow employees to access to the server and do the works. And using remote machines would run everything like email to complex data analysis programs (Strickland, 2008). That is cloud computing. As the one of a team which recently graduated software engineers working on a project to recommend an operating system choosing from either Ubuntu or Windows that able to leverage cloud computing enabling faultless access to the organization data and with services, applications and features that are vibrant and updatable immediately. User interface As most of the employees have better understanding on using Windows more than Ubuntu. This is because Windows’s reputation is far higher than Ubuntu at the outside world. But when come inside to IT field, the result is opposite. This is because Ubuntu has ability to customize the OS and make it more even better.

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...

...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...
