Service compositions build new services by orchestrating a set of existing services. In the Internet of Services there may be many functional similar services, but with different Quality of Service (QoS). Thus a significant research problem in service compositions is how to select the composition’s composite services that the overall QoS of the(More)
Live migration, the process of moving a virtual machine (VM) interruption-free between physical hosts is a core concept in modern data centers. Power management strategies use live migration to consolidate services in a cluster environment and to switch off underutilized machines to save power. However, most migration models do not consider the energy cost(More)

The evolution of service-oriented architectures towards digital ecosystems comprehends a number of challenges. According to Papazoglou et al., one challenge is to develop services in a dynamic environment with high uncertainties, and in collaboration with other companies. The Integrated Service Engineering (ISE) Workbench is a step in this direction in that(More)
One of the mechanisms to achieve energy efficiency in virtualized environments is to consolidate the workload (virtual machines) of underutilized servers and to switch-off these servers all together. Similarly, the workloads of overloaded servers can be distributed onto other servers for a load balancing reason. Central to this approach is the migration of(More)
Currently available mobile devices lack the flexibility and simplicity their users require of them. To start with, most of them rigidly offer impoverished, traditional interactive mechanisms which are not handy for mobile users. Those which are multimodal lack the grace to adapt to the current task and context of their users. Some of the reasons for such(More)
The energy consumption of ICT infrastructures has increased considerably in the recent years. This has resulted in extensive research on dynamic power management strategies as well as data centre design and placement. The main problem with most of the proposed or existing approaches is that they do not fully take the distributed nature of and strong logical(More)

Virtualization and broadband Internet connections enabled existing technologies to form up under the nebulous term cloud. Cloud computing promises near infinite scalability and cost reduction by pay per use agreements. However for data outsourced to existing cloud solutions - which can be considered synonymous with unknown locations and potentially hostile(More)
