Cloud Service Providers Ranking System Using Ontology

The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

In today's business applications, management has to embrace cloud computing for them to succeed in the highly competitive world.

Cloud computing could be visible as Internet-based computing, in which software, the resources shared, and input are created obtainable to hardware 's on request . however utilizing a cloud computing model could

It is crucial that the cloud customer sets up an clearly characterized group to create and support a cloud business technique and execution plan for cloud benefits that will be a part of the entire IT environment. Previously, the proposals, plan, advancement, organization and support of the IT environment was mainly determined by the IT department. Cloud computing is making a development where the business pioneers are getting drawn in light of the fact that they see cloud computing as an instrument to get nearer to their clients and increment sales/income. Adoption of cloud computing is seen as a vital business choice that permits business to enhance IT effectiveness as well as help in accomplishment of worldwide business objectives like

Cloud computing comes up with designers and IT arrangements. capability to concentrate on factors such as providence, attainment and sufficiency planning. Due to increase in complications and costs of management, IT organizations found different models of cloud computing which respond to different needs of various users. National institute of standards and technology (2011) has described that cloud computing has three service models known as software as service(SAAS), Platform as a service (PAAS) and Infrastructure as a service(IAAS).cloud computing provides

While the public cloud has many potential advantages there are several factors that affect the overall success of cloud computing. Customer is considering the migration of some workloads to a cloud provider, and they seek knowledge and experience with assessing the fit and feasibility of these applications.

With the rapid development of processing and storage technologies and the success of the Internet, computing resources have become cheaper, more powerful and more ubiquitously available than ever before. This technological trend has enabled the realization of a new computing model called cloud computing, in which resources (e.g., CPU and storage) are provided as general utilities that can be leased and released by users through the Internet in an on-demand fashion. In a cloud computing environment, the traditional role of service provider is divided into two: the infrastructure providers who manage cloud platforms and lease resources according to a usage-based pricing model, and service providers, who rent resources from one or many infrastructure providers to serve the end users. The emergence of cloud computing has made a tremendous impact on the Information Technology (IT) industry over the past few years, where large companies such as Google, Amazon and Microsoft strive to provide more powerful, reliable and cost-efficient cloud platforms, and business enterprises seek to reshape their business models to gain benefit from this new paradigm. Indeed, cloud computing provides several compelling features that make it attractive to business owners, as shown below.

Cloud computing is an altering technology which is enjoying increasing rates of adoption. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources including networks, servers, storage, applications, and services that can be rapidly provisioned and released with minimal management effort or service provider interaction. The use of Cloud services is proven effective across diverse set of industries, reducing costs associated with computing while increasing flexibility and scalability for computer processes. For instance, Cloud computing services, like Amazon’s, can be used by all business types and more ideal for smaller businesses or especially ideal for businesses just starting. This report is a recommendation for moving all our company’s data center functions on to the cloud. This report outlines supporting details determining how our company could reap the most benefits by adopting cloud services from any of the high-quality cloud service providers available in the market today such as Amazon, Microsoft, Rackspace, and Verizon Terremark cloud services. The benefits of adoption cloud computing services are substantial including reduced infrastructure costs, increased scalability, availability, capacity, speed, backup and mobility. However, these benefits are not free from possible pitfalls. So, to maximize the benefits and minimize risks associated with the move to the cloud, it is

Cloud computing is the collective use of remote servers to handle data, rather than having a local server/computer handling the data. Cloud services provide a lot of convenience to businesses and personal use, because it alleviates the need for costly personal servers/ server maintenance. The issue with implementing this into a business, however, is the dependence on another company’s servers. It also faces security issues such as: lack of direct, physical control over the servers the company uses, reliance on third party security, and possibility of cloud computing resource abuse from hackers. There are three different cloud computing models that can be implemented for the business: Iaas (Infrastructure-as-a-Service), PaaS

Cloud computing has rapidly increased their services for IT infrastructures solutions in the last years, reducing cost of investment of supplies and maintenance becoming a promising concept in the business and IT industry. The cloud provides shared data center, automatic upgrades, security and performance. However, cloud’s safety and standardization have been a challenge when different types of clouds need to be connected. Resource management issues as Quality of service (QoS) and the increasing of complexity and functionality failures are a constant in cloud computing environments, and should be considered by customer when looking for cloud solutions to adapt their organization’s requirements. This paper will explain the

With the growing of technology and people around the world using the internet more often, the cloud is becoming more popular than ever before. The United States National Institute of Standards and Technology has defined cloud computing as follows: "Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction [1]." There are many uses of the cloud but the main uses people use the cloud for is to host websites, store documents, and to stream TV shows and movies. With all this new flooding of the cloud computing network, the dependability of cloud computing systems have come into question for all cloud service providers, consumers, and brokers around the world. Fig. 1 is just one example of the growth of cloud computing of a single company.
