An Introduction to Cloud Computing UKOLN: Supporting The Cultural Heritage Sector
What is Cloud Computing?
Cloud computing is an umbrella term used to refer to Internet based development and services. The cloud is a metaphor for the Internet. A number of characteristics define cloud data, applications services and infrastructure:
1 Remotely hosted: Services or data are hosted on someone else’s infrastructure.
2 Ubiquitous: Services or data are available from anywhere.
3 Commodified: The result is a utility computing model similar to traditional that of traditional utilities, like gas and electricity. You pay for what you would like.
Software as a Service (SaaS)
SaaS is a model of software deployment where an application is hosted as a service provided to customers across the Internet. SaaS is generally used to refer to business software rather than consumer software, which falls under Web 2.0. By removing the need to install and run an application on a user’s own computer it is seen as a way for businesses to get the same benefits as commercial software with smaller cost outlay. Saas also alleviates the burden of software maintenance and support but users relinquish control over software versions and requirements. The other terms that are used in this sphere include Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).
Cloud Storage
Several large Web companies (such as Amazon and Google) are now exploiting the fact that they have data storage capacity which can be hired out to others. This approach, known as ‘cloud storage’ allows data stored remotely to be temporarily cached on desktop computers, mobile phones or other Internet-linked devices. Amazon’s Elastic Compute Cloud (EC2) and Simple Storage Solution (S3) are well known examples.
Data Cloud
Cloud Services can also be used to hold structured data. There has been some discussion of this being a potentially useful notion possibly aligned with the Semantic Web [2], though concerns,

    In other words, cloud computing allows to store all personal and business applications without the data centre. This means that with cloud computing no sophisticated hardware is needed, which leads to great benefits for businesses. Cloud computing provides several hosted services on the Internet. These provided services are divided into three major categories: Software-as-a-Service (SaaS), Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) (Barnatt, 2013).

    This research paper tackles the issues that faces Cloud Computing today and gives the experts and industry’s point of view on the matter. The aspects explored are the significant industry questions that have risen about the use of Cloud Computing, business value, organization impact, adaptability, limitations, initial cost of implementation, and the severe business security risks due to centralization of resources. Brian Proffitt will argue in is IT World article [24], there are some serious limitations with cloud computing that is being blithely ignored such as bandwidth limitation, storage, and availability. Interviews conducted with colleagues that are experts in the Enterprise Systems network arena reveals that, the impact is all in planning before implementation, the selected architecture and the security policy. Findings in manuscripts and online libraries reflect that Cloud Computing is a technological revolution that provides computer resources as a service; offering flexible IT usage, computing efficiency through improved utilization and reduced administration and infrastructure costs. Users are not limited to applications confined to a computer, data stored to a hard drive, or bounded by the organization’s network. Also known as the sum of Software as a Service (SaaS) and Utility Computing, Cloud Computing is argued to be more efficient and scalable. My hope is to identify the common issues that face Cloud Computing in organizations that have implemented it, and find the answer or probable solutions.…

    Cloud computing is simply a new way of looking at and talking about virtual servers. The cloud computing is the emerging technology of delivering many kinds of resources as services, mainly over the Internet. Delivering party is referred to as the service providers, while the users are known as the subscribers. Subscribers pay subscription fees typically on a per-use basis. Cloud computing is broken down into few different categories based on the type of service provided. SaaS (Software as a Service) is the category of cloud computing in which the main resources available as a service are software applications. PaaS (Platform as a Service) is the category/application of cloud computing in which the service providers deliver a computing platform or a solution stack to their subscribers over the Internet. IaaS (Infrastructure as a Service) is the category of cloud computing in which the main resources available as a service are hardware infrastructure. DaaS (Desktop as a Service), which is an emerging –aaS service deals with providing a whole desktop experience over the Internet. This is sometimes referred to as desktop virtualization/virtual desktop or hosted desktop.…
