Abstract: A data volume can be created on a network-accessible storage device in a data center for use by a virtual machine instance. More specifically, a management system of the data center may request storage servers to allocate space for the data volume. Prior to receiving confirmation that the data volume has been created, the management system may further request the storage servers to establish a lease that authorizes the virtual machine access to the data volume.

Abstract: Techniques for preserving the state of virtual machine instances during a migration from a source location to a target location are described herein. A set of credentials configured to provide access to a storage device by a virtual machine instance at the source location is provided to the virtual machine instance. When the migration from the source location to the target location starts, a second set of credentials configured to provide access to a storage device by a virtual machine instance at the source location is provided to the virtual machine instance. During the migration, a response to an input-output request is provided to one or more of the locations using the set of credentials and based at least in part on the state of the migration.

Abstract: A network-based storage resource may implement access control for virtual computing resources that utilize the storage resource during live migration of the virtual computing resources. A network-based storage resource may enforce an access control that limits access to a host of a virtual compute instance. Upon detecting migration of the virtual compute instance, the network-based storage resource may allow a connection to be established with a destination host for the virtual compute instance. The access control mechanism may be updated to limit access to the destination host for data stored for the virtual compute instance at the network-based storage resource.

Abstract: Live migration may be performed for virtual computing resources utilizing network-based storage. A virtual compute instance operating at a source host may be moved to a destination host. The virtual compute instance may be a client of a network-based storage resource that stores data for the virtual compute instance. Access to the data stored for the virtual compute instance may be limited to the source host. When migration is performed, the destination host may be prepared to assume operation of the virtual compute instance. Operation of the virtual compute instance at the source host may be paused and the access to the data at the network-based storage resource may be modified to limit access to the destination host. Operation of the virtual compute instance may then resume at the destination host.
Abstract translation: 可以使用基于网络的存储来对虚拟计算资源进行实时迁移。 在源主机上操作的虚拟计算实例可能被移动到目标主机。 虚拟计算实例可以是存储虚拟计算实例的数据的基于网络的存储资源的客户端。 对虚拟计算实例存储的数据的访问可能被限制到源主机。 当执行迁移时，目标主机可以准备好承担虚拟计算实例的操作。 源主机上的虚拟计算实例的操作可能会被暂停，并且可能会修改对基于网络的存储资源的数据访问，以限制对目标主机的访问。 虚拟计算实例的操作然后可以在目的主机上恢复。

When the migration from the source location to the target location starts, a second set of credentials configured to provide access to a storage device by a virtual machine instance at the source location is provided to the virtual machine instance. During the migration, state information associated with the block storage device is copied from the source location to the target location based on the migration phase.
