Abstract: A system, method and computer-readable medium for request routing based on content popularity information are provided. A client computer transmits a request for content from a content provider. The content provider utilizes executable code, such as translation request code, for facilitating request routing utilizing popularity information. The translation request code, may direct a client computing device to request further translation request code and/or translation information. Thereafter, the client issues a DNS query with the translated information including popularity information. The content delivery network service provider can then either resolve the DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat until a DNS nameserver resolves a DNS query from the client computing device.

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: Resource management techniques, such as cache optimization, are employed to organize resources within caches such that the most requested content (e.g., the most popular content) is more readily available. A service provider utilizes content expiration data as indicative of resource popularity. As resources are requested, the resources propagate through a cache server hierarchy associated with the service provider. More frequently requested resources are maintained at edge cache servers based on shorter expiration data that is reset with each repeated request. Less frequently requested resources are maintained at higher levels of a cache server hierarchy based on longer expiration data associated with cache servers higher on the hierarchy.

Abstract: A system, method and computer-readable medium for client-side processing of resource identifiers. A client request for content is returned that includes information for generating a request for translation information and a number of embedded resource identifiers. Based on the information for generating a request for translation information, the client generates and obtains translation information and processes the embedded resource identifiers to obtain resources from a service provider.

Abstract: A system, method, and computer readable medium for managing resources maintained in resource cache components are provided. A network storage provider storing one or more resources on behalf of a content provider obtains client computing device requests for content. The network storage provider provides resources that are received and maintained on resource cache components. The network storage provider either processes requests or provides notifications to the resource cache components to facilitate the management of resources that need to be updated or are otherwise treated as invalid.

Abstract: A network-based data store may implement retention-based management techniques for data stored at the network-based data store. When data is received for storage at the network-based data store, a retention time for the data may be determined. Storage locations at persistent storage devices of the network-based data store may be selected according to the retention time. The data may then be placed at the storage locations. When a request to delete data is received, retention times of co-located data may be evaluated to determine whether the deletion may be delayed. Delayed deletions may allow the data to be subsequently deleted with at least some of the co-located data. Repair operations to maintain the data according to a durability policy may be modified according to retention time for a data suffering a loss of redundancy.

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 transcoding service is described that is capable of transcoding or otherwise processing content, such as video, audio or multimedia content, by utilizing one or more pipelines. A pipeline can enable a user to submit transcoding jobs (or other processing jobs) into an available pipeline, where a transcoding service (or other such service) assigns one or more computing resources to process the jobs received to each pipeline. The transcoding service and the pipelines can be provided by at least one service provider (e.g., a cloud computing provider) or other such entity to a plurality of customers. A service provider can also provide the computing resources (e.g., servers, virtual machines, etc.) used to process the transcoding jobs from the pipelines.

Abstract: A system, method, and computer readable medium for managing secure content by CDN service providers are provided. A network storage provider stores one or more resources on behalf of a content provider. A CDN service provider obtains client computing device requests for secure content. Based on processing first signature information, the CDN service provider determines whether the secure content is available to the client computing device. If the CDN service provider does not maintain the requested content, the CDN service provider transmits a request to the network storage provider. Based on second signature information and an identifier associated with the CDN service provider, the network storage provider processes the request based policy information associated with the identifier.

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.
