A server node in an IaaS (Infrastructure as a Service) cloud includes a hypervisor arrangement and virtual machine arrangements at least a subset of which together defines at least one application utilizing the IaaS cloud. The server node includes a cloud infrastructure monitor within the hypervisor arrangement. The cloud infrastructure monitor includes a monitor arrangement monitoring an infrastructure of the IaaS cloud by monitoring a physical network, storage within the physical network, the server node, or the virtual machine arrangements. A detector arrangement detects faults within the monitored IaaS infrastructure. A notifying arrangement provides notifications of detected faults on a message bus between the hypervisor arrangement and each at least one application. The message bus relays the fault notifications from the cloud infrastructure monitor to the at least one application. Each at least one application is configured to automatically manage its operation in response to received fault notifications.
