Resources may be isolated for potentially fraudulent virtual compute instances. Resource utilization of virtual compute instances at a host system may be monitored. A virtual compute instance may be identified for fraud mitigation based on the monitored resource utilization. Availability of hardware resources to the identified virtual compute instance may be modified, whereas the availability of the hardware resources may remain for other virtual compute instances not identified for fraud mitigation.

Isolating resources for potentially fraudulent virtual compute instances

Techniques for a device with NUMA a memory architecture to migrate virtual resources between NUMA nodes to reduce resource contention between virtual resources running on the NUMA nodes. In some examples, the device monitors various metrics and/or operations of the NUMA nodes and/or virtual resources, and detect events that indicate that virtual resources running on a same NUMA node are contending, or are likely to contend, for computing resources of the NUMA node. Upon detecting such an event, the device may migrate a virtual resource from the NUMA node to another NUMA node on the device that has an availability of computing resources. The device may then migrate the virtual resource from the overcommitted NUMA node onto the NUMA node that has availability to run the virtual resource. In this way, devices may reduce resource contention among virtual resources running on a same NUMA node.
