Commercially popularized with the year 2002 with the launch of Amazon web services cloud computing has changed the way IT services and resources are delivered to the customers. With its varied platforms like SaaS, PaaS and IaaS it has made available resources which was once never available on demand and scalable manner. With the advantages of high scalability and flexibility, excellent reliability...
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...
Virtualization technologies have grown steadily in the testing and educational environments, owing to their low costs for deploying a wide variety of scenarios. Many applications that provide network node virtualization face scalability problems when larger topologies are created because of their high memory and processing requirements. Although such applications offer methods for load distribution...
Interactive Voice Response (IVR) applications (e.g. automated attendant) are ubiquitous nowadays. Cloud computing is an emerging multi-faceted paradigm (Infrastructure as a Service — IaaS, Platform as a Service — PaaS, and Software as a Service — SaaS) with several inherent benefits (e.g. resource efficiency). Very few, if any, IVR applications are offered today in cloud settings despite all the potential...
Web has become an open platform where everybody can build and run their applications. Big companies can manage the capital expenditure themselves. Small company or a user wants to provide web services, better they can rent the computing infrastructure. Infrastructure-as-a-Service (IaaS) is the delivery of computer infrastructure such as servers, network, applications, storage, software, hardware as...
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...
XYLUS is a virtualized programming environment that addresses coder's mobility, hassle free coding environment, project management and team coordination. It aims to provide a coder or a team of coders to create, manage, develop, compile, execute and share a complete or partial set of development projects on the web without having any development and associated tools. This is mainly achieved through...
Recent economic/financial crisis has posed great difficulties for SMEs in the business operations, making them more cautions in IT investment. In this paper we present an innovative service delivery mechanism by lowering the cost of ownership of IT functions provided by software vendors. For each SME in this service delivery mechanism, a virtual machine instance is dynamically maintained on the computer...
Green computing is a growing research topic. Its goal is to increase energy efficiency and reduced resource consumption. Building infrastructure for cloud computing is one of the methods to achieve these goals. The key concept of cloud computing is to provide a resource sharing model based on virtualization, distributed filesystem and Web services. In this paper, we propose an energy efficient architecture...
This work describes a generic database service for the lightweight Venice Service Grid, which has been developed at the University of Kaiserslautern, Germany. By using Web services any SQL query can be processed and the corresponding result sets are sent back as strongly typed XML documents. The accurately defined interface allows an easy-to-use, platform and programming language independent access...
Many scientific fields routinely generate huge datasets. In many cases, these datasets are not static but rapidly grow in size. Handling these types of datasets, as well as allowing sophisticated queries necessitates scalable distributed database systems, in which scientists are efficiently able to search the datasets. In this paper we present the architecture, implementation and performance analysis...
Technologies associated with virtualization, SOA and grids in the sense of distributed computing have been on a convergence path during the past few years. This convergence allows separating data from the application that uses the data and from the computers that run the applications. Although new applications are certainly possible, perhaps the most revolutionary aspect of this convergence are the...
As an emerging technology and business paradigm, Cloud Computing has taken commercial computing by storm. Cloud computing platforms provide easy access to a company's high-performance computing and storage infrastructure through web services. With cloud computing, the aim is to hide the complexity of IT infrastructure management from its users. At the same time, cloud computing platforms provide massive...
