Abstract:
A support system negotiates secure connections on behalf of multiple guest systems using a set of credentials associated with the guest systems. The operation of the secure connection may be transparent to the guest system such that guest system may send and receive messages that are encrypted or decrypted by the support system, such as a hypervisor. As the support system is in between the guest system and a destination, the support system may act as a local endpoint to the secure connection. Messages may be altered by the support system to indicate to a guest system which communications were secured. The credentials may be managed by the support system such that the guest system does not require access to the credentials.
Abstract:
Update preferences might be utilized to specify that an update to an application should not be applied until the demand for the application falls below a certain threshold. Demand for the application is monitored. The update to the application is applied when the actual demand for the application falls below the specified threshold. The threshold might be set such that updates are deployed during the off-peak periods of demand encountered during a regular demand cycle, such as a diurnal, monthly, or yearly cycle.
Abstract:
Network computing systems may implement data loss prevention (DLP) techniques to reduce or prevent unauthorized use or transmission of confidential information or to implement information controls mandated by statute, regulation, or industry standard. Implementations of network data transmission analysis systems and methods are disclosed that can use contextual information in a DLP policy to monitor data transmitted via the network. The contextual information may include information based on a network user's organizational structure or services or network infrastructure. Some implementations may detect bank card information in network data transmissions. Some of the systems and methods may be implemented on a virtual network overlaid on one or more intermediate physical networks that are used as a substrate network.
Abstract:
In a resource-on-demand environment, dynamically created server instances are allowed to boot from encrypted boot volumes. Access keys to the boot volumes are provided from a key provider that authenticates new instances based on possession of a security token that has been previously shared between the key provider and the new instance through an out-of-band communication.
Abstract:
In certain embodiments, a system includes one or more memory units and one or more processing units. The memory units store blocks that each include a number of identifiers. The memory units include executable instructions that upon execution by the processing units cause the system to receive a request to allocate an identifier to an entity. The request includes data identifying the entity. A target block of identifiers is identified. The target block includes more unallocated identifiers than any other block. The target block is split into first and second blocks. The identifiers of the second block are each higher than any identifier of the first block. The second block is assigned to the entity, and a lowest identifier of the second block is allocated to the entity.

Abstract:
With the advent of virtualization technologies, networks and routing for those networks can now be simulated using commodity hardware. For example, virtualization technologies can be adapted to allow a single physical computing machine to be shared among multiple virtual networks by providing one or more virtual machines simulated in software by the single physical computing machine, with each virtual machine acting as a distinct logical computing system. In addition, as routing can be accomplished through software, additional network setup flexibility can be provided to the virtual network in comparison with hardware-based routing. In some implementations, virtual network setup can be abstracted through the use of resource placement templates, allowing users to create virtual networks compliant with a customer's networking policies without necessarily having knowledge of what those policies are.

Abstract:
In certain embodiments, a system comprises a memory and a processor communicatively coupled to the memory. The memory includes executable instructions that upon execution cause the system to generate, at a first time, a first snapshot capturing data stored in storage units of a storage device. The executable instructions upon execution cause the system to receive an indication to delete at least a portion of the data in the storage units and captured by the first snapshot, and to mark, in response to receiving the indication, the one or more storage units that store the at least a first portion of the data as available. The executable instructions upon execution cause the system to generate, at a second time subsequent to the first time, a second snapshot that omits the one or more storage units marked as available.
