Cloud computing, which can be described as a technology for provisioning computing infrastructure as a service, runtime platform as a service, and software as a service, is considered as a keystone for innovation in the IT area. However, a limiting factor to innovation through cloud computing...

As cloud federation allows companies in need of computational resources to use computational resources hosted by different cloud providers, it reduces the cost of IT infrastructure by lowering capital and operational expenses. This is the result of economies of scale and the possibility for...

Tourism industry/development constitutes one of only a few viable development options and is often the principal source of foreign exchange earnings without exporting any national wealth or resources. It plays an important role in the sustainable development of many developing countries. The...

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...

In this paper, we present an agent-based simulation system that allows modeling the interactions between software buyers and vendors in a software market. The market offers Software-as-a-Service (SaaS) and perpetual software (PS) licenses under different pricing schemes. Four dynamic pricing...

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...

The increasing demand for bandwidth and the error-prone, costly, and long-lasting service provisioning process force carriers to find new ways of automatic service provisioning. Despite the introduction of numerous path computation procedures, suitable for WDM-technology-based networks, very few...

Cloud computing is supposed to offer resources (i.e., data, software, and hardware services) in a manner similar to traditional utilities such as water, electricity, gas, and telephony. However, the current Cloud market is fragmented and static, preventing the successful implementation of...
