  • Publication number: 20180107704
    Abstract: A data store maintaining data may implement reducing input/output (I/O) operations for on-demand data page generation. Log records may be maintained for data pages of data describing changes to the data pages. A coalesce operation may be performed when log records for a data page exceed a coalesce threshold for the data page, applying the log records for the data page to a version of the data page and creating a new version that includes the changes indicated by the log records. An indication may be received to increase the coalesce threshold for a particular data page, delaying to a coalesce operation for the data page according to the increased coalesce threshold. The indication may be received from a storage engine that identifies a delay for the particular data page.

  • Publication number: 20180109610
    Abstract: A service provider may apply customer-selected or customer-defined auto-scaling policies to a cluster of resources (e.g., virtualized computing resource instances or storage resource instances in a MapReduce cluster). Different policies may be applied to different subsets of cluster resources (e.g., different instance groups containing nodes of different types or having different roles). Each policy may define an expression to be evaluated during execution of a distributed application, a scaling action to take if the expression evaluates true, and an amount by which capacity should be increased or decreased. The expression may be dependent on metrics emitted by the application, cluster, or resource instances by default, metrics defined by the client and emitted by the application, or metrics created through aggregation. Metric collection, aggregation and rules evaluation may be performed by a separate service or by cluster components. An API may support auto-scaling policy definition.

  • Publication number: 20180101494
    Abstract: A system that provides virtualized computing resources to clients or subscribers may include an enhanced PCIe endpoint device on which an emulation processor emulates PCIe compliant hardware devices in software. In response to receiving a transaction layer packet that includes a transaction directed to an emulated device, the endpoint device may process the transaction, which may include emulating the target emulated device. The endpoint device may include multiple PCIe controllers and may expose multiple PCIe endpoints to a host computing system. For example, each PCIe controller may be physically coupled to one of multiple host processor sockets or host server SOCs on the host computing system, each of which exposes its own root complex. Traffic received by the PCIe controllers may be merged on the endpoint device for subsequent processing. Traffic originating at one host processor socket may be steered to the PCIe controller to which it is directly attached.

  • Publication number: 20180095774
    Abstract: In a multi-tenant environment, separate virtual machines can be used for configuring and operating different subsets of programmable integrated circuits, such as a Field Programmable Gate Array (FPGA). The programmable integrated circuits can communicate directly with each other within a subset, but cannot communicate between subsets. Generally, all of the subsets of programmable ICs are within a same host server computer within the multi-tenant environment, and are sandboxed or otherwise isolated from each other so that multiple customers can share the resources of the host server computer without knowledge or interference with other customers.

  • Publication number: 20180095670
    Abstract: Methods and apparatus are disclosed for securely erasing partitions of reconfigurable logic devices such as FPGAs in a multi-tenant server environment. In one example, a method of securely erasing an FPGA includes identifying one partition of previously-programmed resources in the FPGA, erasing the identified partition by storing new values in memory or storage elements of the identified partition, and storing new values in memory or storage elements of additional external resources electrically connected to the integrated circuit and associated with the identified partition. Thus, other partitions and subsequent users of the identified partition are prevented from accessing the securely erased data. A configuration circuit, accessible by a host computer via DMA, can be programmed into the FPGA reconfigurable logic for performing the disclosed erasing operations.

    Abstract: Replicated instances in a database environment provide for automatic failover and recovery. A monitoring component can periodically communicate with a primary and a secondary replica for an instance, with each capable of residing in a separate data zone or geographic location to provide a level of reliability and availability. A database running on the primary instance can have information synchronously replicated to the secondary replica at a block level, such that the primary and secondary replicas are in sync. In the event that the monitoring component is not able to communicate with one of the replicas, the monitoring component can attempt to determine whether those replicas can communicate with each other, as well as whether the replicas have the same data generation version. Depending on the state information, the monitoring component can automatically perform a recovery operation, such as to failover to the secondary replica or perform secondary replica recovery.

  • Publication number: 20180054302
    Abstract: Systems and processes are described for a message service with distributed key caching for server-side encryption. Message requests are received by message handlers of the message service that cache data encryption keys used to encrypt and decrypt messages that are stored to message containers in back end storage. A metadata service obtains the data encryption keys from a key management service, caches the keys locally, and sends the keys to the message handlers upon request, where the keys are cached, again. The key management service may generate the data encryption keys based on a master key (e.g., a client's master key). The message handlers may send both message data encrypted using the data encryption key and an encrypted copy of the data encryption key to be stored together in the data store.

    Abstract: Methods and apparatus for private network peering in virtual network environments in which peerings between virtual client private networks on a provider network may be established by clients via an API to a peering service. The peering service and API 104 may allow clients to dynamically establish and manage virtual network transit centers on the provider network at which virtual ports may be established and configured, virtual peerings between private networks may be requested and, if accepted, established, and routing information for the peerings may be specified and exchanged. Once a virtual peering between client private networks is established, packets may be exchanged between the respective client private networks via the peering over the network substrate according to the overlay network technology used by the provider network, for example an encapsulation protocol technology.

  • Publication number: 20180054923
    Abstract: A rack-mountable computer system enables an airflow that cools components in an upstream portion of the computer system interior to be cooled through mixing with a bypass airflow downstream of the components in the upstream portion. The mixed airflow can cool components in a downstream portion of the interior. The bypass airflow is directed by a bypass plenum that is unencompassed by the separate plenum that directs the airflow to cool the upstream portion components. The bypass plenum can be at least partially established by an external surface the computer system and one or more external structures, including an external surface of an adjacently mounted computer system. Relative flow rates through the separate plenums can be adjusted, via flow control elements, to separately control heat removal from components upstream and downstream of the air mixing, based at least in part upon air temperatures in the separate interior portions.

  • Publication number: 20180047002
    Abstract: Data stores that are to be configured as members of a storage group on behalf of a client are identified. The client indicates one or more types of cross-data-store operations to be performed. A transaction manager that makes acceptance decisions for write requests directed to the members based at least partly on contents of a log is instantiated, and respective write transformers are set up for at least some of the types of cross-data-store operations. During a particular time period, the workload at the storage group is monitored, and the number and types of cross-data-store operations is determined. The results of the monitoring are used to determine a billing amount for the client based on a selected pricing policy.

  • Publication number: 20180046552
    Abstract: A log-structured data store implementing data backup may implement variable data replication. Write requests may be received at different storage nodes maintaining respective replicas of a portion of a log for data maintained in the log-structured data store. Log records indicating the write requests may be stored in the respective replicas of the log portions at the different storage nodes. The log records may be sent to a backup data store to be durability persisted as part of an archived version of the log. At some of the storage nodes, in response to determining that the log records have been durably persisted in the backup data store, storage space for the log records may be reclaimed. In other remaining storage nodes, the log records may be retained and made accessible for servicing read requests.

  • Publication number: 20180039307
    Abstract: An air channeling sub-system may include a mechanical cooling section and a direct evaporative cooling section. The direct evaporative cooling section may be downstream from the mechanical cooling section. Cooling air is channeled through the air channeling sub-system and into the room. If a first set of control conditions is met, the air channeling sub-systems is operated in an adiabatic mode. The adiabatic mode includes channeling cooling air through the direct evaporative cooling section to evaporate water into the cooling air. If a second set of control conditions is met, the air channeling sub-system is operated in a hybrid mode. The hybrid mode includes channeling cooling air through the mechanical cooling section to remove heat from the cooling air and channeling the cooling air through the direct evaporative cooling section to evaporate water into the cooling air.

    Abstract: In accordance with a designation of a private alias endpoint as a routing target for traffic directed to a service from within an isolated virtual network of a provider network, a tunneling intermediary receives a baseline packet generated at a compute instance. The baseline packet indicates a public IP (Internet Protocol) address of the service as the destination, and a private IP address of the compute instance as the source. In accordance with a tunneling protocol, the tunneling intermediary generates an encapsulation packet comprising at least a portion of the baseline packet and a header indicating the isolated virtual network. The encapsulation packet is transmitted to a node of the service.

  • Publication number: 20180025065
    Abstract: A probabilistic data structure is generated for efficient query processing using a histogram for unsorted data in a column of a columnar database. A bucket range size is determined for multiples buckets of a histogram of a column in a columnar database table. In at least some embodiments, the histogram may be a height-balanced histogram. A probabilistic data structure is generated to indicate for which particular buckets in the histogram there is a data value stored in the data block. When an indication of a query directed to the column for select data is received, the probabilistic data structure for each of the data blocks storing data for the column may be examined to determine particular ones of the data blocks which do not need to be read in order to service the query for the select data.

  • Publication number: 20180024608
    Abstract: A busway system enables multiple interchangeable power support redundancies to be provided to electrical loads. The busway system includes multiple busways extending through an aisle space, where some busways carry power from separate primary power sources, and one or more busways carry power from a secondary power source. Busways are coupled to loads to provide power support directly to the loads, indirectly via devices that distribute power to the loads via branch circuits, etc. The power support redundancy provided to a load is established based at least in part upon which busways are coupled to the load, and power support redundancies can be changed by changing the couplings of particular busways with the loads. The busways can extend through the aisle space in a staggered configuration to enable load balancing between busways by restricting loads in certain regions of the aisle space to coupling with certain busways and not others.

  • Publication number: 20180004801
    Abstract: Nodes of a database service may receive a read request to perform a read of a record stored by the database service and a transaction request to perform a transaction to the record. First and second indications of time may be associated with the read and transaction, respectively. A potential read anomaly (e.g., fuzzy read, read skew, etc.) may be detected based, at least in part, on a determination that the first indication of time is within a threshold value of the second indication of time. In response to detecting the potential read anomaly, the read may be performed after the transaction specified by the transaction request, regardless of whether the first indication of time is indicative of an earlier point in time than the second indication of time.
