    Abstract: Systems and methods are disclosed which facilitate management of thin provisioned data storage. Specifically, portions of thinly provisioned data stores may be deallocated when they contain invalid data, such as data deleted by a user. A user may transmit notifications, which may include delete notifications, such as TRIM commands, to a provider of the data store (or to the data store itself) that data has been deleted. A management component may modify the data store, or metadata corresponding to the data store, to reflect the deletion. The management component may further monitor portions of the data store to determine whether individual portions contain entirely invalid data. If so, the portion may be deallocated from the thin provisioned data store, resulting in more efficient thin provisioning. Deallocation may be enabled even where deletion notifications from a user do not correspond directly to allocated storage portions.

    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: Secure networking processes, such as packet encapsulation and decapsulation, can be executed upstream of a user or guest operating system provisioned on a host machine, where the user has substantially full access to that machine. The processing can be performed on a device such as a network interface card (NIC), which can have a separate network port for communicating with mapping systems or other devices across a cloud or secure network. A virtual image of the NIC can be provided to the user such that the user can still utilize at least some of the NIC functionality. In some embodiments, the NIC can work with a standalone processor or control host in order to offload much of the processing to the control host. The NIC can further handle headers and payload separately where possible, in order to improve the efficiency of processing the various packets.

    Abstract: Systems and methods are disclosed which facilitate management of thin provisioned data storage. Specifically, portions of thinly provisioned data stores may be deallocated when they contain invalid data, such as data deleted by a user. A user may transmit notifications, which may include write requests corresponding to a defined bit pattern, to a provider of the data store (or to the data store itself) that data has been deleted. A management component may modify the data store, or metadata corresponding to the data store, to reflect the deletion. The management component may further monitor portions of the data store to determine whether individual portions contain entirely invalid data. If so, the portion may be deallocated from the thin provisioned data store, resulting in more efficient thin provisioning. Deallocation may be enabled even where deletion notifications from a user do not correspond directly to allocated storage portions.
