Report In Computer System Example Report In Computer System â€" Assignment Example > Cloud computing system for Anglia CloudIntroductionThis paper is a report for the board of Anglia Cloud explaining the idea, benefits and dangers of cloud computing as well as recommendations of computers, printers, broadband internet connection, network hardware, and network topology suitable for the system. Meaning of cloud computingCloud Computing is a concept that describes provision of IT resources via a network, usually, the internet. Velte et al (2009, p. 4) have stated that cloud computing allow users to acquire computational resources owned and managed by another entity, which is usually a vender or a service provider. These resources include applications (software), platforms and infrastructures, and are provided as a service (Stanoevska-Slabeva, 2009, p. 48). Therefore, a cloud service can be categorized as Software-as-a-Service (SaaS), platform-as-a-Service (PaaS) or infrastructure-as-a-Service (IaaS). Software-as-a-ServiceSoftware-as-a-Service is an idea of software p rovision where the service provider or vendor hosts and distributes applications to clients through a computer network, which is often the internet. SaaS is normally characterized by scalability and on-demand provision. As Roehl-Anderson notes (2010, p. 338) SaaS is increasingly becoming a popular model by which users obtain software; usually, users have the option of scaling up or down the software usage. The service delivery in SaaS can be grouped into two faintly distinct models. One model, which is comparable to application service provider (ASP), is characterized by a service provider hosting and delivering commercially accessible applications to clients through the internet. However, in the other model, the provider delivers via a network an application made purposely for SaaS circulation. Landy and Mastrobattista (2008, p. 86) recognizes the two model of SaaS. Platform-as-a-ServicePlatform-as-a-Service is another form of cloud computing where hardware, operating systems, net work and storage space can be rented and delivered through a network (or the internet). Stanoevska-Slabeva (2009, p. 52) highlights that a “platform is an abstraction layer” separating the virtualized infrastructure and the applications. PaaS is mainly meant to serve the software developers. An example of PaaS distribution is the Google’s App Engine that allows users to run their applications on the company’s infrastructure. Infrastructure-as-a-ServiceInfrastructure-as-a-Service basically involves an organization or rather a client contracting out IT hardware such as servers, networking and storage equipments that are necessary to support certain operations. The out-sourcing entity normally pays for the resources depending on use, while the provider maintains, operates and owns the resources. According to Hurwitz, Bloor, Kaufman and Halper (2009, p. 18) virtualization systems and operating systems (OS) may also be part of the services offered through IaaS. Potential uses a nd relative benefits of cloud servicesThe uses and benefits of cloud computing are enormous. Cloud computing is increasingly being used by organizations to deliver applications and other products to clients. It is an alternative or a supplement to the convention way of distributing products to the consumers. It can be used in connecting mobile workforce in an organization who need to access applications remotely from their computers. Being able to access resources remotely is a huge benefit to users of cloud computing. Through this service, remotely located workers can have access to the resources (applications) they need so long as they have access to the network, or the internet.
