Abstract: A virtual tape library system is used to back up data from a client archive system expecting physical tape operations onto logical data containers and/or a metadata store of a storage service by emulating the physical tape operations. For example, a virtual tape library appliance is installed at a customer premise location to interface with a client archive system. The virtual tape library appliance provides virtual interfaces to appear as physical tape library subsystems, such as tape drives and media changing interfaces. However, these virtual interfaces are supported by logical data containers in a storage service and a metadata store. The virtual tape library system allows the client archive system to make requests to import new virtual tapes, export virtual tapes for archiving, store virtual tapes at a virtual location, load and eject virtual tapes into a virtual tape drive and operate on virtual tapes in a virtual tape drive.

Abstract: High-speed processing of packets to, and from, a virtualization environment can be provided while utilizing hardware-based segmentation offload and other such functionality. A hardware vendor such as a network interface card (NIC) manufacturer can enable the hardware to support open and proprietary stateless tunneling in conjunction with a protocol such as single root I/O virtualization (SR-IOV) in order to implement a virtualized overlay network. The hardware can utilize various rules, for example, that can be used by the NIC to perform certain actions, such as to encapsulate egress packets and decapsulate packets.

Abstract: Processes and systems are disclosed for selecting a producer system from a number of producer systems to lease to a consumer system. A leasing agent, in response to a request from the consumer system for access to a service at a producer system, can identify a producer system to lease to the lease requestor based, at least in part, on a selection weight associated with each producer system that the leasing agent is assigned. The selection weights can be modified based on status information associated with each of the producer systems. This status information may be obtain from the producer systems and/or from a consumer system that has previously accessed the producer system. The consumer system may provide the status information to the leasing agent as part of the consumer system's lease request.

Abstract: Systems and method for the management of migrations of virtual machine instances are provided. A migration manager monitors the resource usage of a virtual machine instance over time in order to create a migration profile. When migration of a virtual machine instance is desired, the migration manager schedules the migration to occur such that the migration conforms to the migration profile.

Abstract: A directed acyclic graph (DAG) is generated to represent a namespace of a directory. In response to a request to create a new object with a specified name, a hash value bit sequence is computed for the name. A plurality of levels of the DAG are navigated using successive subsequences of the bit sequence to identify a candidate node for storing a new entry corresponding to the specified name. If the candidate node meets a split criterion, the new entry and at least a selected subset of entries of the candidate node's list of entries are distributed among a plurality of DAG nodes, including at least one new DAG node, using respective bit sequences obtained by applying the hash function for each distributed entry.

Abstract: A virtual tape system utilizes multiple virtual tape libraries. Some virtual elements of the virtual tape libraries are connected elements, such as virtual import/export slots, that logically connect two or more virtual tape libraries. Virtual media changers of the virtual tape libraries can be commanded, as if physical media changers, to virtually move virtual media, such as virtual tapes, within and among the virtual tape libraries. By moving a virtual medium to a connected element, the virtual medium can be virtually moved from one virtual tape library to another.

Abstract: In response to a rename request to change a file name at a storage service from a first name to a second name, a workflow comprising at least two atomic operations is initiated. In the first atomic operation, a lock is obtained on a first directory entry for the first name, and an intent record for the rename workflow is stored. In a second atomic operation, a pointer of a second directory entry for the second name is modified, and an indication of the pointer modification is stored. In a third set of operations, the intent record is deleted, the lock is released, and the first directory entry is deleted.

Abstract: Attempts to update confirmation information or firmware for a hardware device can be monitored using a secure counter that is configured to monotonically adjust a current value of the secure counter for each update or update attempt. The value of the counter can be determined every time the validity of the firmware is confirmed, and this value can be stored to a secure location. At subsequent times, such as during a boot process, the actual value of the counter can be determined and compared with the expected value. If the values do not match, such that the firmware may be in an unexpected state, an action can be taken, such as to prevent access to, or isolate, the hardware until such time as the firmware can be validated or updated to an expected state.

Abstract: In this disclosure, techniques are described for more efficiently sharing resources across multiple virtual machine instances. For example, techniques are disclosed for allowing additional virtual machine instances to be supported by a single computing system by more efficiently allocating memory to virtual machine instances by providing page swapping in a virtualized environment and/or predictive page swapping. In one embodiment, a virtual memory manager swaps pages predicatively in and/or out of a paging pool based on information from a central processing unit (“CPU”) scheduler. In one embodiment, the CPU scheduler provides scheduling information for virtual machine instances to the virtual memory manager, where the scheduling information allows the virtual memory manager to determine when a virtual machine is scheduled to become active or inactive. The virtual memory manager can then swap-in or swap-out memory pages.
