Abstract: A node of a distributed storage service receives a read request from a client, directed to a particular physical page storing at least a portion of a file store object. The node transmits, to the client, a particular operation sequence number (OSN), obtained from a replicated state machine, indicative of an order in which the read request was processed at the node relative to other requests directed to the file store object. The node receives a write request from the client directed to the page. The write request includes the particular OSN. The node determines whether the page has been modified after the particular OSN was obtained. If the page has not been modified since the OSN was obtained, a modification indicated in the write request is performed; otherwise, the write request is rejected.
Abstract translation: 分布式存储服务的节点从客户端接收指向存储文件存储对象的至少一部分的特定物理页的读取请求。 节点向客户端发送从复制状态机获得的特定操作序列号（OSN），其指示相对于针对文件存储对象的其他请求，该节点处理该读取请求的顺序。 节点从客户端接收指向页面的写入请求。 写请求包括特定的OSN。 该节点确定在获得特定OSN之后页面是否已被修改。 如果自获得OSN以来页面未被修改，则执行在写入请求中指示的修改; 否则写请求被拒绝。

Abstract: Methods and apparatus for WAN-optimized cache population at a storage gateway appliance are disclosed. A read request is received at the appliance from a client. The request is directed to a particular data block of a data chunk of a storage object of a remote storage service. A method comprises, in response to the read request, initiating a first data transfer of the data chunk from the remote storage service to an intermediate device. The method includes determining, based on one or more criteria, contents of one or more other data transfers including a second data transfer from the intermediate device to the appliance, initiating the second data transfer to transmit the requested data block to the appliance, and providing the particular data block to the client from the appliance.

Abstract: Virtual machines may migrate between heterogeneous sets of implementation resources in a manner that allows the virtual machines to efficiently and effectively adapt to new implementation resources. Furthermore, virtual machines may change types during migration without terminating the virtual machines. Migration templates may be established to manage migration of sets of virtual machines between sets of implementation resources and/or virtual machine types. Migration templates may be established based at least in part on information provided by migration agents added to the virtual machines under consideration for migration. The migration agents may detect and augment relevant virtual machine capabilities, as well as trigger reconfiguration of virtual machine components in accordance with migration templates.

Abstract: Some embodiments facilitate high performance packet-processing by enabling one or more processors that perform packet-processing to determine whether to enter an idle state or similar state. As network packets usually arrive or are transmitted in batches, the processors of some embodiments determine that more packets may be coming down a multi-stage pipeline upon receiving a first packet for processing. As a result, the processors may stay awake for a duration of time in anticipation of an incoming packet. Some embodiments keep track of the last packet that entered the first stage of the pipeline and compare that with a packet that the processor just processed in a pipeline stage to determine whether there may be more packets coming that need processing. In some embodiments, a processor may also look at a queue length of a queue associated with an upstream stage to determine whether more packets may be coming.
Abstract translation: 一些实施例通过启用执行分组处理的一个或多个处理器来确定是否进入空闲状态或类似状态来促进高性能分组处理。 随着网络分组通常到达或批量传输，一些实施例的处理器确定在接收到用于处理的第一分组时，更多分组可能在多级流水线中下降。 结果，处理器可以在预期输入分组的情况下保持清醒一段时间。 一些实施例跟踪进入流水线的第一阶段的最后一个分组，并将其与处理器刚刚在流水线级中处理的分组进行比较，以确定是否可能有更多的分组需要处理。 在一些实施例中，处理器还可以查看与上游级相关联的队列的队列长度，以确定更多分组是否可能来临。

Abstract: Information about the transmission of packets or other information can be inferred based at least in part upon the state of one or more queues used to transmit that information. In a networking example, a hook can be added to a free buffer API call from a queue of a NIC driver. When a packet is transmitted and a buffer freed, the hook can cause information for that packet to be transmitted to an appropriate location, such as a network traffic control component or control plane component, whereby that information can be compared with packet, source, and other such information to infer which packets have been transmitted, which packets are pending, and other such information. This information can be used for various purposes, such as to dynamically adjust the allocation of a resource (e.g., a NIC) to various sources based at least in part upon the monitored behavior.
Abstract translation: 可以至少部分地基于用于发送该信息的一个或多个队列的状态来推断关于分组或其他信息的传输的信息。 在网络示例中，可以将钩子添加到来自NIC驱动程序队列的空闲缓冲区API调用。 当分组被发送并且缓冲器被释放时，钩子可以使得该分组的信息被发送到适当的位置，诸如网络流量控制组件或控制平面组件，由此该信息可以与分组，源和 其他这样的信息来推断哪些分组已被发送，哪个分组正在等待，以及其他这样的信息。 该信息可以用于各种目的，例如至少部分地基于所监视的行为来动态调整资源（例如，NIC）到各种源的分配。

Abstract: Systems and method for the management of migrations of virtual machine instances are provided. A migration manager monitors a resource usable for migration of a virtual machine instance in order to predict availability of the migration resource. When migration of a virtual machine instance is desired, the migration manager schedules the migration to occur at a future point in time identified based on the predicted availability of the migration resource.

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: Processes and systems are disclosed for leasing a producer virtual machine on behalf of a consumer virtual machine in an overlay network. The consumer host of the consumer virtual machine can communicate with a set of leasing agents to obtain the identity of a number of producer virtual machines capable of providing the consumer virtual machine with access to a service. When the consumer virtual machine attempts to communicate with a producer system, the consumer host can identify a producer host that hosts a target producer virtual machine and redirect a service request to the producer host.
