Cloud computing faces two business-related issues. First, the management of clouds requires not only technical skills but also the understanding of the business side of these systems. Traditional distributed systems research did not require this understanding, simply assuming that all components...

Cloud computing aims at allowing customers to utilize computational resources and software hosted by service providers. Thus, it shifts the complex and tedious resource and software management tasks typically done by customers to the service providers. Besides promising to eliminate these...

IP/MPLS service providers rely on transport networks to provide bandwidth on demand with the lowest possible provisioning time. However, due to the static nature of transport networks and the differences in the communication languages and switching systems, the IP/MPLS and transport network...

Low liquidity of cloud markets can result in market instability and inefficiency, preventing the successful implementation of ubiquitous computing on demand. To circumvent this issue, it has been suggested to channel demand and supply into a limited number of standardized services. These...

Service markets allow users to discover, purchase, and utilize services offered on a specific platform. As service platforms grow in number of users and variety of offerings, it raises the question of whether this phenomenon continues to benefit users. Based on a literature review, the paper...

IT service businesses can achieve economies of scale and scope faster than in traditional product businesses. In particular, as IT service platforms will become the founding infrastructure of our economies, the analysis and understanding of the value that a service platform can generate is of...

The current access policies and funding schemes of computing e-infrastructures represent a huge challenge for the sustainable growth of computing e-infrastructures and a serious jeopardy for investments made into these e-infrastructures. In order to be able to address these issues, the economics...

This paper investigates the impact of determination of an original initiator of transmission on demand as well as profits of the providers. For that purpose we present a new model, called differentiated traffic-based interconnection agreement (DTIA) that differentiates traffic into two types,...

This paper applies the theory of social networks to P2P systems, creating a social-network-based P2P network topology formation algorithm for file sharing. The algorithm extends the Gnutella P2P file sharing technology, which uses super nodes for searching and for relaying shared files between...

While the h-Index and the g-Index (as the major indices for quantifying the academic performance of researchers) take into consideration the citation count of publications, some other important indicators of research output (i.e. the number of authors per paper, lead author, year of publication)...
