With the emergence of X-as-a-Service (e.g., software as a service, platform as a service, and infrastructure as a service), QoS (quality of service) delivery is becoming increasingly important as users are becoming more and more demanding on good or better services. Traditional service delivery mainly focuses on function or information provisioning, and leaves behind service quality. In this pa...

While Cloud services offer flexibility, scalability and economies of scale, there have been commensurate concerns about security. As more data moves from centrally located server storage to the Cloud, the potential for personal and private data to be compromised will increase. Confidentiality, availability and integrity of data are at risk if appropriate measures are not put in place prior to s...

Quality-of-service and SLA guarantees are among the major challenges of cloud-based services. In this paper we first present a new cloud model called SLAaaS – SLA aware Service. SLAaaS considers QoS levels and SLA as first class citizens of cloud-based services. This model is orthogonal to other SaaS, PaaS, and IaaS cloud models, and may apply to any of them. More specifically we make three con...

Looking at today's services and applications offered in an increasingly interconnected world, there is a trend towards a variety of services and applications developed for very specific tasks. But instead of providing large, monolithic applications, complex applications are now stitched together based on interoperable services, which is known as service composition in the Service Oriented Archi...

This paper presents the NEFFICS platform, which is a software platform as a basis for a new innovation driven ecology for networked enterprises, extended on top of an established cloud-based, software-as-a-service business operation platform, combined with an advanced innovation management software platform. The business context and value of the new platform will be demonstrated and validated i...

Development of InformationSystems based on territorial data (e.g., land planning, geo-marketing, vehicle management, traffic guidance, . . . ) is usually highly complex and expensive. A large part of the cost is due to the fact that the real value of geographical data for a given application purpose is highly dependent from the match between data quality characteristics and the application targ...

Industrialization has led to efficiency and effectiveness gains in manufacturing industries. Industrialization approaches such as standardization or sourcing are also key concepts in modern service companies. Therefore, current IS research studies how to transfer industrialization approaches to IT service production in order to increase efficiency and effectiveness. Automated and integrated val...

Instead of using traditional learning environments which contain tools and content of a single provider that are often owned by one specific educational organization, the presented idea of Widgetand Cloud-based Personal Learning Environments (PLEs) exploits a variety of existing and developing open educational sources including popular Web2.0 resources such as YouTube, Flickr or Wikipedia. The ...
