Abstract: Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. In order to increase the speed of provisioning, a data replication may be provision with less than the total number of nodes to be included in the group. Once an initial set of nodes have been provisioned and are implementing a consensus protocol, the data replication group may begin to receive traffic. Furthermore, new nodes may be added to the group until the total number of nodes for the group has been reached.

Abstract: Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. During the execution of the set of nodes various nodes may become stale or otherwise obtain a state that is inconsistent with at least one other node of the data replication group. A catch up algorithm may be employed in which a set of teachers is initialized, the various node which may be stale may select a teacher from the set of teachers and perform learning operations. This process may be repeated until the state of the various nodes is current with at least one other node of the data replication group.

Abstract: Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. In order to increase the speed of provisioning, a pool of data replication groups may be maintained. When a request is received a data replication group may be selected from the pool, removed from the pool, and associated with the request. Furthermore, a replacement data replication group may be provisioned and added to the pool.

Abstract: Generally described, one or more aspects of the present application relate to a public snapshot service for creating and managing block-level snapshots on a cloud provider network. Storage locations for each block that comprise the snapshot can be enumerated on a snapshot manifest. Identification of storage location for a requested snapshot block can be improved using a manifest index.

Abstract: Generally described, one or more aspects of the present application relate to a public snapshot service for creating and managing block-level snapshots. Snapshots can be configured to enable writing at the sub-block level. Subsequent modifications made to blocks storage volume that forms the basis of the snapshots can be backed up as a sub-block level operations.

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.

Abstract: A data storage system includes a head node and mass storage devices. The head node is configured to flush data stored in a storage of the head node, based at least in part on one or more triggers being met, from the storage of the head node to a set of the mass storage devices of the data storage system. The flushed data is written to a segment of free storage space across the set of the mass storage devices allocated for the given data flush operation. In some embodiments, a head node may flush both current version data and point-in-time version data to the set of mass storage devices. Also, the data storage system maintains an index that indicates storage locations of data for particular portions of a volume before and after the data is flushed to the set of mass storage devices.
