Cloud computing is a massively central advancement in the technique that businesses and users devour and work on computing. It's a elementary modify to an prepared model in which applications don't subsist out their lives on a specific section of hardware and in which possessions are more supplely deployed than was the historical standard. It's a primary shift to expansion and utilization model that...
Web has become an open platform where everybody can build and run their applications. Big companies can manage the expenditure themselves. Small company or a single user wants to create web services, better they can rent the computing infrastructure. All the big companies are investing heavily on this Cloud technology. Few notable, important and popular cloud based products are g-mail and yahoo mail...
The creating of reusable mobile solutions is influenced by many factors. The platforms are arbitrary, the target audience can be new to mobile software, and the devices are not always online and restricted in their computational capabilities. This paper presents an archetype pattern- and REST-driven approach for building customizable, flexible, and efficient mobile business applications. Furthermore,...
Cloud computing is a buzzword terminology applied to several nascent trends in the turbulent landscape of information technology. Computing in the "cloud" alludes to ubiquitous and inexhaustible on-demand IT resources accessible through the Internet. In the era of cloud computing, whole lifecycle of telecommunication services, especially service deployment, present new features. In this...
Software as a service (SaaS) is an emerging software framework in which business data and logic typically integrate with other applications. It requires a unified subscriber to describe SaaS to make for easy integration, however, SaaS provides services to different tenants by running only one instance. In order to satisfy personalized needs from different tenants, the business logic becomes correspondingly...
Cloud computing is causing a paradigm shift in the provision and use of computing services, away from the traditional desktop form to online services. This implies that the manner in which these computing services are tested should also change. This paper discusses the research issues that cloud computing imposes on software testing. These issues were gathered during interviews with industry practitioners...
The lack of license management schemes in distributed environments is becoming a major obstacle for the commercial adoption of Grid or Cloud infrastructures. In this paper, we present a complete license management architecture that enables a pay-per-use license management which can be deployed together with an on-demand computing scenario. Our architecture enables authenticated access to a remote...
It is obvious that big, complex enterprise systems are hard to manage. What is not obvious is how to make them more manageable. There are two traditional solutions for management in IT systems. One relies on administrators, but there are lacks of experienced administrators. The other relies on systems themselves, but there are no important progresses in related technologies about self-management,...
A recent survey of the 451group on Cloud usage highlights software licensing as one of the top five obstacles for Cloud computing, quite similar to what has been observed in the Grid already a couple of years. The reasons are the same: the current praxis of software licensing, both in terms of business models and licensing technology. As a consequence, using commercial applications that require access...
The Software as a Service (SaaS) methodology is a key paradigm of Cloud computing. In this paper, we focus on an interesting topic - to implement a Cloud computing functionality, the SaaS model, on existing production Grid infrastructures. In general, production Grids employ a Job-Submission-Execution (JSE) model with rigid access interfaces. In this paper we develop the Cyberaide onServe, a lightweight...
The service and cloud computing oriented architecture is a very promising architecture for practical implementation of the next generation geographical information systems. This paper investigated the service and cloud computing oriented architecture for constructing a distributed and web service enabled geographical information platform. The spatial cloud computing applies geographical information...
Business agility is of vital importance to chemical and petroleum industry, especially in rapid response to diagnose and exchange of real-time information and other relevant data sources. From IT perspective, emerging delivery models such as cloud computing offer the possibility to build the elastic infrastructure and flexible computing platform, thus enable enterprises to focus on their core competences...
While the emergence of clouds had lead to a significant paradigm shift in business and research, cloud computing is still in its infancy. Specifically, there is no effective publication and discovery service nor are cloud services easy to use. This paper presents a new technology for offering ease of discovery, selection and use of clusters hosted within clouds. By improving these services, cloud...
To follow the technology advancement and satisfy the needs on the RTI software in the “Cloud computing” age, a scheme of remodeling the traditional RTI software to be with “Platform as a Service (PaaS)” architecture was proposed. Software construction, sub-component functions and the method of interacting based on the remodeled RTI software on the WAN were studied. The focus was scheduling computing...
In this paper, we present a REST-based SOA system, Set It Right (SIR), where people can get feedback on and help with short texts. The rapid development of the SIR system, enabled by designing it as a set of services, and also leveraging commercially offered services, illustrates the strength of the SOA paradigm. Finally, we evaluate the Cloud Computing techniques and infrastructures used to deploy...
Many companies aim to use Web services to integrate heterogeneous and /or remote application in SOA (Service Oriented Architecture) contexts. The SaaS (Software as a Service) economical model allows to link service consumption and pricing. We aim to consider e learning as a set of services, hosted according to Cloud Computing techniques. We based our work on a concrete industrial product.
Cloud computing is a recent trend in IT that moves computing and data away from desktop and portable PCs into large data centers, and outsources the “applications” (hardware and software) as services over the Internet. Cloud computing promises to increase the velocity with which applications are deployed, increase innovation, and lower costs, all while increasing business agility. But, is the migration...
Cloud Computing Environments enable business agility and enterprises to exploit/respond quickly to changes in the marketplace, competition, technology and operational environment. For enterprises, CCE present a number of issues and challenges. Some of these include the inability to take advantage of the dynamic resource elasticity of CCE, issues of data fragmentation and duplication, the challenge...
Desktop virtualization is a new delivery method in which desktop operating systems execute in a data center and users access their applications using stateless "thin-client" devices. This paradigm promises significant benefits in terms of data security, flexibility, and reduction of the total cost of ownership. It is important to further improve this approach while maintaining good user...
Today, when the Internet is concerned, one seldom thinks about the network itself and the TCP/IP suite only. With the boom of Web applications, Internet services, new business models and innovative computing paradigms (e.g. software-as-a-service model and cloud computing), the Internet has evolved into an indispensable social infrastructure and the largest computing platform of the world as well....
