Cloud computing is a computational model in which resource providers can offer on-demand services to clients in a transparent way. However, to be able to guarantee quality of service without limiting the number of accepted requests, providers must be able to dynamically manage the available resources so that they can be optimized. This dynamic resource(More)
Fault tolerance techniques can improve the trust of users in service oriented architectures as they can ensure data availability. This paper presents an implementation of a novel fault tolerance mechanism in a SOA architecture which simultaneously provides increased availability and better quality of service. In addition to this mechanism, a service(More)
This paper presents an approach to provide quality of service for IoT-Cloud users through a dynamic virtual machine allocation algorithm on a Metascheduler. Although there are others reactive approach to handle with general cases of virtual machine allocation and placement, they may have not optimal performance for IoT workload, because it aggregates a new(More)
