Configuration fragments developed separately and focusing on different aspects, such as availability, security or performance of a system need to be integrated into a consistent system configuration to avoid system malfunctions. The main challenges of such integration are due to the overlapping entities and the integration relations between the entities of the different configuration fragments. In...
A system configuration consists of many entities with many configuration attributes that are interrelated by system constraints. A system configuration is consistent when all the constraints are satisfied by the entities, their attributes and relations. At runtime a system configuration may be modified for instance in response to changes in the system environment or for security/performance fine-tuning...
A system configuration is a set of configuration entities, their relations and the rules the system should obey. At runtime the configuration may be modified to meet new requirements, in response to performance degradations, or due to upgrade. Such modifications should maintain the consistency of the configuration to avoid any malfunction and service outage. Thus there is a need for runtime validation,...
High-Availability requires hardware and software redundancy. Virtualization is a technique - among others - for improving the utilization of hardware resources by making virtual (rather than actual) versions of hardware, operating system, etc. and collocating them on the same hardware. In virtualized environments virtual machines (VMs) are used for the deployment of the software entities. When VMs...
