...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 experience...

...GREEN CLOUD COMPUTING ABSTRACT: Cloud computing is a highly scalable and cost-effective infrastructure for running HPC, enterprise and Web applications. However, the growing demand of Cloud infrastructure has drastically increased the energy consumption of data centers, which has become a critical issue. High energy consumption not only translates to high operational cost, which reduces the profit margin of Cloud providers, but also leads to high carbon emissions which is not environmentally friendly. Hence, energy-efficient solutions are required to minimize the impact of Cloud computing on the environment. In order to design such solutions, deep analysis of Cloud is required with respect to their power efficiency. Thus, in this chapter, I discuss various elements of Clouds which contribute to the total energy consumption and how it is addressed in the literature. I also discuss the implication of these solutions for future research directions to enable green Cloud computing. The paper also explains the role of Cloud users in achieving this goal.

...- 2011 Cloud Hooks: Security and Privacy Issues in Cloud Computing Wayne A. Jansen, NIST Abstract In meteorology, the most destructive extratropical cyclones evolve with the formation of a bent-back front and cloud head separated from the main polar-front, creating a hook that completely encircles a pocket of warm air with colder air. The most damaging winds occur near the tip of the hook. The cloud hook formation provides a useful analogy for cloud computing, in which the most acute obstacles with outsourced services (i.e., the cloud hook) are security and privacy issues. This paper identifies key issues, which are believed to have long-term significance in cloud computing security and privacy, based on documented problems and exhibited weaknesses. • applications can be developed upon and deployed. It can reduce the cost and complexity of buying, housing, and managing hardware and software components of the platform. Infrastructure-as-a-Service (IaaS) enables a software deployment model in which the basic computing infrastructure of servers, software, and network equipment is provided as an on-demand service upon which a platform to develop and execute applications can be founded. It can be used to avoid buying, housing, and managing the basic hardware and software infrastructure components. 1.

...Security Issues in Cloud Computing”. As of today, cloud computing is a flexible, cost-efficient, and established transfer platform for giving business or user IT services on the internet. Yet, cloud computing presents an additional level of risk because crucial services are time and again outsourced to a moderator. This makes it more difficult to uphold data security, privacy, support data, service availability, and validate compliance. It is my goal to discuss some of the current issues involved with the cloud and how important that they are to everyone. What is Cloud? Cloud computing is a capable computing regular where computing resources in big data points are made accessible as services over the internet. It has become a renowned IT by presenting a professional atmosphere for data storage capability. It is a standard for computing and is provides a striking, enormous, significant asset that contains any subscription-based or pay-per-use service over the web. Cloud is on-demand admission to virtualized IT services and products. Places like Amazon and Google are presently giving such services, by charging customers by means of an on-demand strategy. Being that consumers put their sensitive information on the clouds public domains, huge problems for cloud implementation are lack of security and access control. The key obstacle is that the doubtful info drifts as service providers can access numerous computer-generated mechanisms in clouds. The cloud takes virtual infrastructure...

...Introduction Cloud computing has the potential to change the face of the Information Technology (IT) industry. Industry experts maintain that the cloud will eventually become a primary component of computing activities conducted over the Internet. Presently, major corporations like Google, Amazon, Microsoft, and IBM have embraced this trend and are using the technology to enhance IT supported services. As the number of benefits and potential uses of the technology grows, the funding earmarked for assessments and implementation of cloud services will likely multiply. Cloud computing consists of immense benefits that allows end users to utilize services that include infrastructure, applications, data storage capacity. Last year, the Brookings Institution released a study that endorses the benefits of cloud computing to the government. The writer of the study, Darrell West, who is the vice president and director of government studies at Brookings, stated in the paper, “that agencies that have moved to the cloud generally enjoyed 25percent to 50 percent savings on their IT cost. For the federal government as a whole, this translates into billions in cost savings, depending on the scope of the transition” (West, 2011). Cloud computing consist of a network of servers that run services that are operated as shared platforms. The characteristics of cloud computing include on-demand services, pay-per-use services, broadband network access, multi-tenancy, rapid elasticity and scalability...

...Cloud Computing Cloud computing is the delivery of computing as a service rather than a product. Resources like software and information are provided to computers and communication devices as a utility like electricity or water. This cloud computing service is done through a computer network, which is the internet typically. Cloud computing is known as encapsulation by some users since the physical location and configuration of how the resources are shared to the devices is often not revealed to the end user. It is like using the electricity. The end user doesn’t have to know the whereabouts of the physical location where the electricity is produced nor how the components are configured from there to their home. They just use the feature or resource instead. Similar to this cloud computing describes the consumption of IT services through the common most computer network available in the world, the internet. Virtualized resources can be shared remotely with ease-of-access exploiting the facilities provided by the internet. The end user must have a tool or an application (Web Browser) installed on their local computers which provides the platform for the sharing of resources. Providers of cloud computing deliver applications or tools via the internet, which are accessed using web browsers and desktop mobile apps, while the main resources (business software and data) are stored in a server located in a remote location. Screen-sharing technology is used sometimes to provide...
