Virtual Network Architecture For Cloud Computing Essay

In the past a few years, the rapid advances in technology had brought us more challenges in adopting emerging technologies and pedagogies in our teaching and learning environment. As our school is committed to developing, implementing, and maintaining quality education programs, it becomes imperative to utilize updated technology to address the changing demand of students. However, the cost and time to develop the information, software, and resources is too high for us. Facing the high cost of providing computing infrastructure and software by traditional independent software vendors, I have examined the possibility of deploying a private cloud computing system in our school to help cut down our technology expense, and the implementation

Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but

(3) Web Services in the Cloud - instead of delivering full applications, this service allows users to access APIs for added functionality.

This seems like an odd question to ask since you probably already have some concept of "the cloud." However, given some of the conversations I have been having recently, I think there 's a good deal of cloudy thinking about cloud computing.

The infrastructure of the cloud provides a multi-tenant configuration in which software deployed in virtual machines, is accessed by multiple users concurrently across heterogeneous environments. Though verifying software through evidence can provide a means for trust, the consumer would demand the authenticity of that trusted service. The possibilities for the consumer not able to fully trust are that, there is no governance or authority to certify the resources. Hence a third party authority generally called as the cloud auditor should verify and certify the service instance which is generally termed as attestation process.

In doing a small business, most small companies usually have a lot of stuff to be stored safely including their application, files, data, business record, customer's information, and to name a few. As a result, most of the small businesses would continuously have problems finding space for all their necessary data when there is a disaster happen. In a realm of science fiction has become a reality with cloud computing which allows all kind of information to be widely and safely stored on the infinite space of the World Wide Web instead of in a limited area of physical drives. Therefore, many small businesses have been moving to cloud computing to keep their business sustainability and experiencing the new technologies that were never

Cloud computing is revolutionizing the use software globally at a very rapid pace as it is completely redefining the economics of how software is purchased and used. Web 2.0 technologies and their underlying design precepts are responsible for the current and future generations of social networks (Bernoff, Li, 2008). Both have immediate and significant impacts on the operations of businesses and the major contributions each makes are explained in this analysis.

The public cloud is a deployment model where cloud services are provided over a public network, such as the internet, by a third-party provider. Examples of public cloud services include Dropbox, Gmail and Twitter. By definition, most SaaS applications operate under the public cloud deployment model. One of the primary advantages of public cloud is its attractive pricing model. The organisation is typically charged a subscription fee for access to the cloud services, paying only for the number of users required, this removes the need for business to manage software licences (Savvas [Online], 2014). However, security conscious organisations requiring a SaaS solution may opt for a private cloud segregated from public networks. There are obvious security concerns involved in exposing a SaaS application to a public network. However, there are concrete steps an organisation can take to reduce the risk incurred with public cloud deployments. Many public cloud SaaS providers offer two-factor authentication, requiring an additional level of verification before the user’s credentials are accepted. This is typically achieved using an authentication code in the form of a text message sent to the user’s registered mobile number. Furthermore, organisations should develop and maintain a culture of cyber security, enforce best practices such as creating strong passwords and training staff in phishing awareness.

Over the past several years the term cloud computing has become common in homes and organizations alike. Cloud computing can be defined as a pooled set of computing resources that are furnished via the internet. There are three types of cloud services typically available, these services are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Organizations can benefit greatly from cloud services because they eliminate the need to buy and manage physical resources. Although such an action cuts cost it leaves organization victim to the vulnerabilities and threats that exist in cloud computing. Throughout this paper I will discuss the vulnerabilities and threats that come

The word "cloud" is used to represent the internet and other communications systems. Cloud computing is the result of an evolution of the widespread adoption of virtualization, service-oriented architecture, autonomic, and utility computing in the past, telecommunications companies mainly gave simply dedicated, point-to-point data circuits to their users. Starting from the 1990's, virtual private network services was included in their contributions. It made the telecommunication companies offer equally improved services whereby cutting down on cost as well as using resources effectively.

Abstract – Cloud computing is a type of computing that relies on sharing a pool of physical and/or virtual resources (e.g., networks, servers, storage, applications and services), rather than deploying local or personal hardware and software. This technology is mainly service oriented and focuses on cost reduction, hardware reduction and pay just for service concept. Virtualization in cloud computing is making a virtual image of the storage devices servers or network resources so that they can be used on multiple machines at the same time.

This project is going to discuss about the Cloud Computing and its application in business. To briefly describe what cloud

Nowadays, with the development of technology, the demand for high speed computing for the computers increases significantly. Cloud computing is the most emphasized Information and Communications Technology (ICT) which can effectively implement high speed computing [1]. Most common products that people used in their daily life such as cloud drive and Google search are based on cloud computing, therefore it is necessary to

The traditional model of software distribution, in which software is purchased for and installed on personal computers, is
