Abstract: Various aspects of a data volume or other shared resource are determined and updated dynamically for purposes such as to provide guaranteed qualities of service. For example, the number of partitions in a data volume and/or the way in which data is stored across those partitions can be updated dynamically without significantly impacting the customer using the volume. The data stored to the volume can be striped or otherwise distributed across a number of logical areas, which then can be distributed across the partitions. Separate mappings can be used for the data in each logical area, and the logical areas in each partition, such that when moving a logical area only a single mapping has to be updated, regardless of the amount of data in that logical area. Further, logical areas can be moved between partitions without the need to repartition or redistributed the data in the data volume.

Abstract: Patterns of access and/or behavior can be analyzed and persisted for use in pre-fetching data from a physical storage device. In at least some embodiments, data can be aggregated across volumes, instances, users, applications, or other such entities, and that data can be analyzed to attempt to determine patterns for any of those entities. The patterns and/or analysis can be persisted such that the information is not lost in the event of a reboot or other such occurrence. Further, aspects such as load and availability across the network can be analyzed to determine where to send and/or store data that is pre-fetched from disk or other such storage in order to reduce latency while preventing bottlenecks or other such issues with resource availability.

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: Usage of shared resources can be managed by enabling users to obtain different types of guarantees at different times for various types and/or levels of resource capacity. A user can select to have an amount or rate of capacity dedicated to that user. A user can also select reserved capacity for at least a portion of the requests, tasks, or program execution for that user, where the user has priority to that capacity but other users can utilize the excess capacity during other periods. Users can alternatively specify to use the excess capacity or other variable, non-guaranteed capacity. The capacity can be for any appropriate functional aspect of a resource, such as computational capacity, throughput, latency, bandwidth, and storage. Users can submit bids for various types and combinations of excess capacity, and winning bids can receive dedicated use of the excess capacity for at least a period of time.

Abstract: A system, method and computer-readable medium for request routing based on application information associated with the requested resource are provided. A DNS nameserver at an application broker obtains a DNS query corresponding to a resource requested from a client computing device and associated with a first resource identifier. The first resource identifier includes application information associated with the requested resource. Based on the application information parsed from the first resource identifier, the DNS nameserver at the application broker selects either a second resource identifier which resolves to a domain of a network computing provider or an IP address associated with a network computing component for processing the requested resource. The DNS nameserver then transmits either the second resource identifier or IP address to the client computing device.

Abstract: A system, method, and computer readable medium for managing CDN service providers 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 updates request processing information based on the process requests for content. The network storage provider then makes a recommendation regarding initialization of a CDN service provider as a function of the updated request processing information. Subsequent client computing device requests for resources can be provided to the recommended CDN service provider utilizing alternative resource identifiers.

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: The effects on networking systems of attacks on vulnerabilities, such as vulnerable modules in a webserver, SYN flooding, etc, can be devastating to a network environment. In various embodiments, a first, quick, or inexpensive analysis is performed on incoming network flows. If an intrusion issue or other problem is suspected based on the first, rapid, or an inexpensive analysis, then the flow can be flagged for redirection to another process, virtual machine, or physical computer module that will perform a deeper, more expensive analysis on the network flow. If there are no issues detected in the second, deeper analysis, then the network flow can be forwarded to its intended recipient. If an issue is detected in the second, deeper analysis, then the network flow can be throttled, quarantined, ignored, sent to an un-trusted portion of the system, sent for more analysis, or otherwise handled or flagged.

Abstract: A system, method, and computer readable medium for managing registration, by a content broker, of one or more resources with one or more service providers are provided. A content broker obtains registration information for registering the one or more resources with a service provider. The registration information may include a request to publish one or more resources to a service provider, an identification of the one or more resources, service provider selection criteria provided by the content provider or otherwise selected, and the like. The content broker transmits a service provider generation request corresponding to the registration information to the service provider. Then, the content broker manages and processes data pursuant to registration of the one or more resources with the service provider.

Abstract: To facilitate log streaming in a computing cloud, application service providers may dynamically provision one or more named log streams. A file-oriented interface to log streams may be made available to a plurality of virtual computer system instances used to provide the application services. Application service providers may further dynamically provision one or more sets of log stream processing agents arranged in one or more log stream processing graphs. Particular log streams may be assigned to particular log stream processing graphs for real-time processing. Processed log streams and/or associated data may be stored for later inspection. Such provisioning and/or configuration may be performed with a unified Web-based interface.

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, 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 form the client computing device.
