...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...

...INTRODUCTION Cloud computing has boost a large amount of interest in the IT industry. The market research and analysis firm IDC suggests that the market for cloud computing services was $16bn in 2008 and will rise to $42bn/year by 2012 (Chhabra, Verma &ump; Taneja, 2010) .The era of cloud computing introduces a new dimension for Enterprises. The academia and research worlds have developed a keen interest into challenges and issues introduced by this relatively new concept (Sriram &ump; Khajeh-Hosseini, 2009). As experienced by large or small companies while adopting cloud computing technology, the issues can be outlined as security, privacy, data migration as (Hosseini, et al., 2010 ). Adoption of cloud technology by enterprises especially those are using KBE (knowledge based engineering) systems are in risk in terms of migration their data over the cloud. Most enterprises are in a midst of creating, sharing, streaming and storing data in digital formats to allow collaboration , hence there is a need to continuously managed and protect the data to ensure its value and authenticity (Yale &ump; Chow, 2011). Enterprises now acquire increasingly more information about their products, customers and partners- whether it’s stored in a cloud environment or not and failure to protect this data can be damaging. Partners and clients anticipate their information will be constantly protected before conducting business with a company. Within lay the need for complete data governance to...

...Trust in Cloud Computing Sarah Kim University of Texas at Austin 1616 Guadalupe Suite #5.202 Austin, TX 78701-1213 srhkim@gmail.com ABSTRACT Ayoung Yoon University of North Carolina at Chapel Hill 216 Lenoir Dr. CB #3360 100 Manning Hall, Chapel Hill, NC 27599 ayyoon@email.unc.edu journalists, IT experts, and scholars have addressed challenges of trust in cloud computing often accompanied with concerns for security, privacy, diminishing user control, lack of transparency, and reputation issues (e.g., Ghosh & Arce, 2010; Kahn & Malluhi, 2010; Pearson & Benameur, 2010; Habib, Ries, & Muhlhauser, 2010). Many of the trust-related discussions, however, are often based on the viewpoints of service developers/providers or technology focused (e.g., Hwang & Li, 2010). Cloud service providers (CSPs) saying “trust me” does not necessarily motivate people to respond with “I trust you.” Understanding of users’ thoughts on trust issues in the cloud computing environment is necessary in order to build and preserve trust between users and cloud service providers. PURPOSE OF RESEARCH The present study explores individual end-users’ perspectives of cloud computing, especially issues regarding their trust/distrust of cloud services. While current cloud computing service development focuses on adoption by enterprises and organizations, individual endusers who use cloud services in their everyday lives also constitute an important consumer group. Challenges of trust in cloud computing have gained...

...2014 Hybrid cloud 2014 Hybrid cloud Introduction A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and has others provided externally. For example, an organization might use a public cloud service, such as Amazon Simple Storage Service (Amazon S3) for archived data but continue to maintain in-house storage for operational customer data. Market Survey According to Forrester study, hybrid model of implementing IaaS is particularly enticing for US and European enterprises. 28% of hardware decision-makers report using a hybrid cloud strategy for server resources today, and nearly half predict that they will have workloads in both traditional/on-premises and hosted/service provider cloud environments by 2016. This new architecture will bring unfamiliar challenges, as IT works to integrate resources and workloads in their data centers with those at a cloud service provider. Having infrastructure resources at two locations connected via the network creates need for a whole new level of integrated visibility, management, and orchestration. Hybrid cloud architectures let firm’s provision capacity for typical workload needs and use cloud service provider capacity for demand spikes. This saves them from having to purchase mostly idle peak server capacity for peak needs, such as an extra 50% for end of quarter financial closing or 10x capacity for web marketing flash crowds. And firms only pay for the capacity...

...The Reality about Clouds and the Security Challenges They Pose Clouds are an extremely practical and obvious solution to data storage management. However, there is a critical need to securely store, manage, and share (structured and unstructured) amounts of data. “The major security challenge with clouds is that the owner of the data may not have control of where the data is placed. Therefore, we need to safeguard the data in the midst of untrusted processes. There are numerous security issues for cloud computing. For example, the networks that connects the system in a cloud has to be secure. Mapping the virtual machines to the physical machines has to be carried at securely. Since data in the cloud will be placed anywhere, it is important that the data is encrypted. As a result, it is critical that this data be protected and only given to authorized individuals. Access control is a key concern, because insider attacks are a huge risk. A cloud can be private or public. A public cloud sells services to anyone on the Internet. (Currently, Amazon Web Services is the largest public cloud provider.) A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people. When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services (Rouse, M. 2013)...

...Review 8 References 14 Research Skills 1. Research Proposal 2.1. Rationale and Context Cambridge City Government is an institution that is currently facing problems with the management of its information transfer over the internet. This is seen in the need to align data, particularly revenue streams, incomes and expenditures. In fact, the situation is worsened by an increasing city population, as well as amenities complexities that are placing a strain on the available internet facilities that serve the institution. As such, the proposed research study intends to analyse the role that cloud computing could play in solving the information transfer problems that face the government. The research results will act as the blueprint for the city administrators to develop and implement networking management approaches that will address its needs. I assume that if cloud computing is determined to be advantageous for the government, then its implementation will make it easier for the institution to meet its information management needs. This proposal describes the approach to research that will be adopted for the proposed study. Kenrick et al. (2010, pp. 293-294) argue that the cognitively driven constructs and context of any research would aid it in accepting the intellectual journey applied in the identification of the research problem. In this respect, it is better to understand the context of the research and the cognitively driven constructs that make up the search for...

Threats of New Entrants 7 III. Bargaining Power of Clients (and Customers) 8 IV. Threats of Substitutes 9 V. Bargaining Power of Suppliers 10 Works Cited 11 Overview of Cloud Computing National Institute of Standards and Technology defines Cloud computing as the ability for users to have on-demand access to a shared pool of compute resources called the cloud infrastructure. The cloud infrastructure can be viewed as containing both a physical layer and an abstraction layer. The physical layer consists of the hardware resources that are necessary to support the cloud services being provided, and typically includes server, storage and network components. The abstraction layer consists of the software deployed across the physical layer, which manifests the essential cloud characteristics. Conceptually the abstraction layer sits above the physical layer (NIST, 2011). The graphic above from NIST defines the Essential Characters, Service Models, and Deployment Models for Cloud Computing. Using Michael Porter’s Five Forces Model (Schilling, p. 74-76), we can examine the challenges that impact Cloud Computing from 5 perspectives as detailed in the sections below. * Rivalry among existing competitors * Threats of New Entrants * Bargaining...
