Abstract: A computer apparatus (100) includes an OS execution unit (120), an OS-dependent interrupt processing unit (110), and an OS-independent interrupt processing unit (130). When an OS-independent interrupt (201) due to a state of a device (200) occurs, the OS-independent interrupt processing unit (130) determines whether or not to initiate a task (145). When the task (145) is to be initiated, the OS-independent interrupt processing unit (130) turns on the flag (141) and causes the OS execution unit (120) to generate an OS-dependent interrupt (202). When the OS-dependent interrupt (202) is generated, the OS-dependent interrupt processing unit (110) determines whether or not the flag (141) is on, and when the flag (141) is on, initiates the task (145) and turns off the flag (141).

Abstract: Technologies for hybrid virtualization and secure enclave include a computing device and an edge orchestrator. The edge orchestrator securely provisions a container-enclave policy to the computing device. A VMM of the computing device constructs a platform services enclave that includes the container-enclave policy. The platform services enclave requests a local attestation report from an application enclave, and the application enclave generates the attestation report using secure enclave support of a compute engine of the computing device. The attestation report is indicative of a virtualization context of the application enclave, and may include a VM flag, a VMM flag, and a source address of the application enclave. The platform services enclave enforces the container-enclave policy based on the virtualization context of the application enclave. The platform services enclave may control access to functions of the computing device based on the virtualization context.

Abstract: Techniques for migrating servers from customer networks into service provider networks are described. A backup proxy can be deployed in a customer's network and associated with one or more servers in the customer's network and with a server migration service of a service provider network. A customer can identify a server in the customer's network to migrate and the server migration service coordinates the migration with the backup proxy. The backup proxy can be instructed to obtain replication data for the server, obtain configuration data associated with the server, and upload the replication data and configuration data to the service provider network. The service provider network uses the replication data and configuration data to create a migrated copy of the server at the service provider network.
