Abstract: A request to copy at least a portion of a first network that includes a first set of devices is received, the request including one or more filtering criteria, with at least one of the one or more filtering criteria specifying a tag assigned to a device of the first set of devices. At least the portion of the first network is copied by causing the system to create, according to the one or more filtering criteria, a second network by causing a second set of devices to be configured to be duplicative of devices of the first set of devices that are assigned the tag specified by the filtering criteria.

Abstract: A system, method, and computer-readable medium for updating request routing information associated with client location information are provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a resource identifier for requested content from the client computing device. The content delivery network service provider obtains a query IP address corresponding to the client computing device. Based on routing information associated with the query IP address, the content delivery network service provider routes the DNS query. The process further includes monitoring performance data associated with the transmission of the requested resource and updating routing information associated with the query IP address based on the performance data for use in processing subsequent requests from the client computing device.

Abstract: A system and method for management and processing of resource requests are provided. A content delivery network service provider receives a DNS query from a client computing device corresponding to a requested resource from the client computing device. The content delivery network service provider associates the requested content into a set of content segments. For each content segment, the content delivery network service provider identifies the network address of a registered content provider, such as peer computing device, and a cache component of the content delivery service provider. The content delivery network service provider also provides tokens for requesting the content from a registered content provider. The client computing device obtains the content from the registered content providers and/or the cache component of the content delivery network service provider.

Abstract: A system and method for content distribution are provided. A content provider generates a network topology having one or more subnetworks made up of content sources. The content provider segments content, such as applications, into segments for distribution. The content provider then distributes the content such that for each identified subnetwork, each content segment is distributed to a content source. Subsequent, client computing device requests for content can be serviced by selecting a content source in a particular subnetwork selected for delivering the requested content to the client computing device to minimize traffic flow of the requested content through the nodes of the distribution network.

Abstract: A system and method for management and processing of resource requests is provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a requested resource from the client computing device. The content delivery network service provider associates the client computing device with a cluster of other client computing devices. Based on routing information for the cluster, the content delivery network service provider routes the DNS query. The process can further include monitoring performance data associated with the delivery of the requested resource and updating the routing information for the cluster based on the performance data for use in processing subsequent requests from client computing devices in the cluster.

Abstract: A system, method, and computer readable medium for managing network storage provider and CDN service providers are provided. A content broker component obtains client computing device requests for content provided by a content provider. The content broker processes the client computing device requests and determines whether a subsequent request for the resource should be directed to a network storage provider or a CDN service provider as a function of the updated or processed by the content broker.

Abstract: A natural language understanding model is trained using respective natural language example inputs corresponding to a plurality of applications. A determination is made as to whether a value of a first parameter of a first application is to be obtained using a natural language interaction. Using the natural language understanding model, at least a portion of the first application is generated.

Abstract: A determination is made as to whether a value of a first parameter of a first application is to be obtained using a natural language interaction. Based on received input, a first service of a plurality of services is identified. The first service is to be used to perform a first task associated with the first parameter. Portions of the first application to determine the value of the first parameter and to invoke the first service are generated.

Abstract: Systems and methods dynamically manage replicas of data sets. A collection of data stores is used to redundantly store one or more replicas of one or more data sets. The replicas may be used to respond to read requests from multiple sources. Upon identification of a need to allocate storage space to a data object, space used by one or more of the replicas is allocated to the data object. Various parameters may be utilized in the selection of one or more replicas whose storage space can be allocated to the data object. The parameters may be based at least in part on characteristics of the one or more data sets relative to one another.

Abstract: A computer system that provides clients access to pooled resources in order to provide computing or data storage services may receive service requests (which explicitly or implicitly include requests for pooled resources), may service at least some of those requests, and may determine pricing for the serviced requests. The pricing for each request may be dependent on whether it was serviced using a portion of a resource pool that was reserved for the use of the client on whose behalf it was received or using burst capacity (e.g., unreserved or otherwise idle capacity within the resource pool). Pricing for the use of reserved capacity may be fixed, regardless of the amount of reserved capacity used. Pricing for burst capacity may depend on actual use, and may be demand-based (e.g., using a spot-market-based dynamic pricing model). Clients with reserved capacity may optionally request access to burst capacity.

Abstract: A system and method for management and processing of resource requests are provided. A content delivery network service provider receives a DNS query from a client computing device corresponding to a requested resource from the client computing device. The content delivery network service provider associates the requested content into a set of content segments. For each content segment, the content delivery network service provider identifies the network address of a registered content provider, such as peer computing device, and a cache component of the content delivery service provider. The content delivery network service provider also provides tokens for requesting the content from a registered content provider. The client computing device obtains the content from the registered content providers and/or the cache component of the content delivery network service provider.

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.

Abstract: A distributed system for collecting and processing packet routing information is provided. A service provider, such as a content delivery network service provider, can maintain multiple Points of Presence (“POPs”). Routing computing devices associated with each POP can forward information about the packet routing information to a packet routing management component. The packet routing component can process the information provided by the various POPs. The packet routing component can then update, or otherwise modify, packet routing information used by one or more of the POPs. Accordingly, the packet routing management component can then selectively distribute the updated or modified packet routing information, including the distribution to all POPs, the targeted distribution to specific POPs and the creation of centrally accessible routing information.

Abstract: A system, method and computer-readable medium for client-side cache management are provided. A client request for content is returned that includes executable code for generating a request for preload information. Based on processing the executable code, a client computing device requests preload information from a content delivery service provider. The content delivery service provider provides an identification of content based on resource requests previously served by the content delivery service provider. The client computing device processes the preload information and generates and obtains identified resources for maintenance in a client computing device memory, such as cache.

Abstract: A group of computers is configured to implement a block storage service. The block storage service includes a block-level storage for storing data from a set of distinct computing instances for a set of distinct users. An interface is configured to allow the set of distinct users to specify respective destinations for storing backup copies of respective data stored in the block-level storage for the distinct users. At least some of the respective destinations are for different storage systems remote from one another. A backup copy function is provided for creating backup copies of data stored in the block-level storage by the set of distinct computing instances for the set of distinct users. The backup copies are stored in different destination locations specified by respective ones of the plurality of distinct users via the interface.

Abstract: A hosted analytics system may be integrated with transactional data systems and additional data sources such real-time systems and log files. A data processing pipeline may transform data on arrival for incorporation into an n-dimensional cube. Correlation between patterns of events in transactional data may be identified. Upon arrival, new data may be transformed and incorporated into the n-dimensional cube. Similarity between the new data and a previously identified correlation may be determined and flagged.

Abstract: Replicated instances in a distributed computing environment provide for automatic failover and recovery. A component monitors the status of event processors in a set or bucket and handles the failure of an event processor. For a large number of instances, the data environment can be partitioned such that each monitoring component is assigned a partition of the workload. At intervals, each event processor sends a “heartbeat” message to the event processors in the bucket covering the same workload partition, to inform the other event processors of the status of the event processor sending the heartbeat. If it is determined that a heartbeat is received from each event processor in the bucket, a current process can continue. In the event of monitoring component failure, the instances can be repartitioned, and the remaining monitoring components can be assigned to the new partitions to substantially evenly distribute the workload.

Abstract: A computer-implemented method routes service requests to services in a service framework provided by a plurality of hosts. The method comprises receiving a service request for a service in the service framework and discovering a plurality of candidate hosts that host the service. The plurality of candidate hosts are a subset of the plurality of hosts. The method further comprises selecting a candidate host from the plurality of candidate hosts based on measured latencies for the plurality of candidate hosts and routing the service request to the selected candidate host.
