Abstract: Generally described, one or more aspects of the present application relate to an instance cloning service for cloning a running virtual machine instance and configuring the resources of the new virtual machine instance created by cloning the running virtual machine instance. For example, the instance cloning service can create the new virtual machine instance and attach it to a storage volume to which the original virtual machine instance is attached. The instance cloning service may subsequently move the new virtual machine instance to another storage volume (e.g., based on a user request or based on the performance of the instances). Alternatively, upon cloning, the instance cloning service may attach the new virtual machine instance to a new storage volume. For example, the instance cloning service may use copy-on-write to provide the new virtual machine instance with its own storage volume.

Abstract: This disclosure describes systems, devices, and techniques for migrating virtualized resources between the main region and edge locations. Live migration enables virtualized resources to remain operational during migration. Edge locations are typically separated from secure data centers via the Internet, a direct connection, or some other intermediate network. Accordingly, to place virtualized resources within an edge location, the virtualized resources must be migrated over a secure communication tunnel that can protect virtualized resource data during transmission over the intermediate network. The secure communication tunnel may have limited data throughput. To efficiently utilize resources of the secure communication tunnel, and to reduce the impact of migrations on virtualized resource operations, virtualized resource migrations may be carefully scheduled in advance. For instance, virtualized resources may be selectively migrated at times-of-day in which they are likely to be relatively idle, or at times when the communication tunnel is predicted to have sufficient bandwidth.

Abstract: Methods and apparatus for post data synchronization in live migration of domains. Host devices on a network may implement virtual machines (VMs) as domains in an execution environment, and may provide local persistent storage for data of the VMs. A migration technique for moving a domain including the persistent data from one host device to another host device is described in which the VM is instantiated on the target device, and the domain is switched to the target device. Synchronization of the VM's data from the persistent storage on the source device to the target device is then initiated, for example according to a distributed replicated storage technique that makes the target device's persistent storage the primary storage and the source device's persistent storage the secondary storage for the VM. Once the data is synchronized, the VM and its respective storage on the source device are released.
