  • Patent number: 11153182
    Abstract: Policies can be applied to, and enforced for, specific resources by applying a corresponding tag to those resources. An entity, such as a customer of a resource provider, can generate one or more policies to be applied to a set of resources, where those policies can relate to data retention, backup, lifecycle events, and other such aspects. Each policy can be associated with a particular tag, which may comprise a key-value pair to be applied to various resources. A policy enforcement manager can determine the tagged resources and ensure that the relevant policies are applied. The policies can include logic or intelligence for performing a variety of tasks with respect to resources, groups of resources, or types of resources, as identified using the tags.

  • Publication number: 20210318895
    Abstract: A computing system that provides virtual computing services may generate and manage remote computing sessions between client computing devices and virtual desktop instances hosted on the service provider's network. A computing resource instance manager may monitor connections to and disconnections from a virtual desktop instance during particular time periods, and may apply a resource management policy to determine whether and when to shut down an underlying virtualized computing resource instance following a disconnection (e.g., immediately, after some period of time, or only between certain hours). A storage volume for the virtual desktop instance may be detached during a shutdown. In response to a reconnection request, the virtualized computing resource instance (or another such instance) may be restarted and the storage volume may be reattached. The computing resource instance manager may develop a model for predicting when to shut down or restart an instance based on historical data or machine learning.

  • Patent number: 10909094
    Abstract: Systems and methods are provided to implement a metadata record migration system that schedules the migrations of metadata records that are frequently mutated. In embodiments, the scheduler collects timing data of jobs that modify the metadata records, including the timing of various mutation operations within the jobs. In embodiments, when it is determined that a metadata record is to be migrated to a different storage location, the scheduler determines a time to migrate the metadata record. The migration time may lie within a migration window, selected based on an expected migration time needed for the metadata record and the collected time data in order to reduce a probability that record mutations will occur during the migration. In embodiments, the jobs may be snapshot jobs that modify a snapshot record, and the migration may be performed as a result of a cell partitioning operation occurring within the snapshotting system.

  • Publication number: 20200322138
    Abstract: Generally described, one or more aspects of the present application correspond to techniques for creating encrypted block store volumes of data from unencrypted object storage snapshots of the volumes. These encryption techniques use a special pool of servers for performing the encryption. These encryption servers are not accessible to users, and they perform encryption and pass encrypted volumes to other block store servers for user access. The encryption context for the volumes can be persisted on the encryption severs for as long as needed for encryption and not shared with the user-facing servers in order to prevent user access to encryption context.

  • Patent number: 10740156
    Abstract: A router receives a request to access a resource. In response to the request, the router identifies routing metadata comprising first metadata specifying a first location of the resource and a first merit value and second metadata specifying a second location of the resource and a second merit value. The router determines, based at least in part on the first merit value of the first metadata and the second merit value of the second metadata, an authoritative state of the resource associated with the first location or the second location. Based at least in part on the determination, the router identifies a preferred location for a new resource. In the event of a rollback, merit values are assigned to cause a reversal of the preferred path for the creation of new resources.

  • Patent number: 10623370
    Abstract: Virtual workspaces can be provided using shared resources and network-attached storage. A workspace client can access a virtual workspace created under a customer account. For specific types of data, such as pixel data used to render the display component of the workspace on the workspace client, the data can be prevented from being transmitted over a public network. Private security gateway interfaces can be created in the customer environment that can be attached to respective security gateways in the workspace environment. Routing rules are configured such that pixel data for a workspace is only transmitted to the workspace client through a security gateway and over a secure connection to the corresponding private gateway interface in the customer environment, which can direct the pixel data to the workspace client.

  • Patent number: 10620866
    Abstract: A system partitions a graph representation of relationships between block devices and associated snapshots into a plurality of cells to more evenly distribute computing resource usage attributable to the block devices and snapshots. The relationships may be analyzed to determine resource usage associated with the block devices and/or the snapshots wherein the resource usage corresponds to a mutation operation rate or number of mutation operations performed (or scheduled for performance). As a result of determining that the resource usage for a given cell exceeds a predetermined threshold for resource usage, the cell may be partitioned into a plurality of cells, and a portion of the corresponding block device(s), and subsequent snapshot(s) generated therefrom, may be assigned to the new cell.

  • Patent number: 10452453
    Abstract: A router of a block-level data storage service receives a request to generate a snapshot of a block device. The router, based on routing metadata for the block-level data storage service, identifies active metadata that indicates a first cell that may maintain the block device and alternate metadata that indicates a second cell that may maintain the block device. Based on a first state of the block device in the first cell, a second state of the block device in the second cell, and a predetermined set of rules defining operations corresponding to outcomes associated with the first state and the second state, the router determines which of the first cell and the second cell authoritatively maintains the block device. The router transmits the request to the appropriate cell in accordance with the predetermined set of rules.
