The digital ecosystem (DE) paradigm is a holistic management/design/integration paradigm that is based on the notion of self-interested, self-managing, proactive and autonomous digital entities that evolve and self-organize. While a DE can be realized using different technologies Web services (WS) are particularly promising due to their widespread acceptance within industry and academia, established...
Many critical activities rely on the correct and uninterrupted operation of networked Computer Information Systems (CIS). Such systems are however exposed to many different kinds of risk, and thus many researches have been taking place for enabling them to perform self monitoring and self healing to maintain their operation over time as specified by domain policies. This capability is often referred...
The problem of finding efficient workload distribution techniques is becoming increasingly important today for heterogeneous distributed systems where the availability of compute nodes may change spontaneously over time. Therefore, the resource-allocation policy must be designed to be robust with respect to absence and re-emergence of compute nodes so that the performance of the system is maximized...
