Abstract: Approaches are described for enabling a host computing device to store credentials and other security information useful for recovering the state of the host computing device in a secure store, such as a trusted platform module (TPM) on the host computing device. When recovering the host computing device in the event of a failure (e.g., power outage, network failure, etc.), the host computing device can obtain the necessary credentials from the secure store and use those credentials to boot various services, restore the state of the host and perform various other functions. In addition, the secure store (e.g., TPM) may provide boot firmware measurement and remote attestation of the host computing devices to other devices on a network, such as when the recovering host needs to communicate with the other devices on the network.

Abstract: A set of techniques is described for enabling a user of a virtual resource to specify to the hosting system a preferred performance parameter such as throughput, latency, CPU utilization, or the like. The hosting system then dynamically tunes the underlying resources to favor the preferred performance parameter. Tuning the settings may include adjusting various batching and moderating processes that are available on the hosting device, such as enabling/disabling interrupt coalescing, enabling/disabling segmentation offload, increasing or decreasing the size of a ring buffer used to share data between several resources, batching input/output (I/O) operations and the like. For example, if the user has indicated that lower latency is preferable, the hosting system may disable interrupt coalescing; whereas if the user has indicated that higher throughput should be favored, the hosting system may enable interrupt coalescing.

Abstract: The transmission of data on computer networks according to one or more policies is disclosed. A policy may specify, among other things, various parameters which are to be followed when transmitting initiating network traffic. Multiple network interfaces may be installed on a server to enable transmission of data from the single server according a number of discrete configuration settings implicated by the various policies. The multiple network interfaces may correspond to separate physical components, with each component configured independently to implement a feature of a policy. The multiple network interfaces may also correspond to a single physical component that exposes multiple network interfaces, both to the network and to the server on which it is installed.

Abstract: Host machines and other devices performing synchronized operations can be dispersed across multiple racks in a data center to provide additional buffer capacity and to reduce the likelihood of congestion. The level of dispersion can depend on factors such as the level of oversubscription, as it can be undesirable in a highly connected network to push excessive host traffic into the aggregation fabric. As oversubscription levels increase, the amount of dispersion can be reduced and two or more host machines can be clustered on a given rack, or otherwise connected through the same edge switch. By clustering a portion of the machines, some of the host traffic can be redirected by the respective edge switch without entering the aggregation fabric. When provisioning hosts for a customer, application, or synchronized operation, for example, the levels of clustering and dispersion can be balanced to minimize the likelihood for congestion throughout the network.

Abstract: Operating profiles for consumers of computing resources may be automatically determined based on an analysis of actual resource usage measurements and other operating metrics. Measurements may be taken while a consumer, such as a virtual machine instance, uses computing resources, such as those provided by a host. A profile may be dynamically determined based on those measurements. Profiles may be generalized such that groups of consumers with similar usage profiles are associated with a single profile. Assignment decisions may be made based on the profiles, and computing resources may be reallocated or oversubscribed if the profiles indicate that the consumers are unlikely to fully utilize the resources reserved for them. Oversubscribed resources may be monitored, and consumers may be transferred to different resource providers if contention for resources is too high.

Abstract: Approaches are described for updating code and/or instructions in one or more computing devices. In particular, various embodiments provide approaches for updating the microcode of one or more processors of a computing device without requiring a restart of the computing device and without disrupting the various components (e.g., applications, virtual machines, etc.) executing on the computing device. The microcode updates can be performed on host computing devices deployed in a resource center of a service provider (e.g., cloud computing service provider), where each host computing device may be executing a hypervisor hosting multiple guest virtual machines (or other guest applications) for the customers of the service provider.

Abstract: A backup battery unit that can be reconfigured to provide different currents and/or voltages depending upon load conditions. The backup battery unit can be reconfigured, for example, between a configuration in which battery cells for the battery unit are wired in series to a configuration where the battery cells are wired in parallel. Additional embodiments are directed to a backup battery unit that can isolate a battery cell and remove the cell from a circuit for the battery while the battery is under load or being charged. The isolated cell can then be serviced or tested.

Abstract: Systems and methods for handling resources in a computer system differently in certain situations, such as catastrophic events, based upon an assigned layer of the resource to the system. The layer can be based, for example, on criticality of the resource to the system. Services or computing device resources can be physically segregated in accordance with layers and can be managed in accordance with the segregation. In response to receiving information about an event, the different layers can be handled in accordance with their criticality, for example by shutting some of the resources down and/or slowing some of the resources down.
