摘要： Methods and apparatus for implementing anycast flow stickiness in stateful sessions are described. For the first packet from a source device to an anycast group, a destination anycast endpoint is selected from the anycast group by a routing process via an algorithm that is specified for the anycast group. A record of the mapping of the source device to the destination anycast endpoint may be stored. Additional packets in the flow are routed to the same anycast endpoint as the first packet according to the stored information. Alternatively, a hashing technique may be used to route packets to an anycast endpoint. The packets may be encapsulated in an encapsulation format that includes network substrate routing information to the destination anycast endpoint; anycast forwarding decisions are made at the overlay network level and not at the network substrate level, and thus flow stickiness can be maintained.

摘要： 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.

摘要： 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.

摘要： A system, method and computer-readable medium for request routing based on cost information are provided. A client request processing a resource identifier for requested content transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of cost information. The client computing device then issues a second DNS query to the same content delivery network service provider. The content delivery network service provider can then either resolve the second 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 with the content delivery network service provider's network until a DNS nameserver resolves a DNS query from the client computing device.

摘要： Aspects of a data environment, such as the creation, provisioning, and management of data stores and instances, are managed using a separate control environment. A user can call into an interface of the control environment, the call being analyzed to determine actions to be performed in the data environment. A monitoring component of the control plane also can periodically communicate with the data environment to determine any necessary actions to be performed, such as to recover from faults or events in the data environment. A workflow can be instantiated that includes tasks necessary to perform the action. For each task, state information can be passed to a component in the data environment operable to perform the task, until all tasks for an action are completed. Data in the data environment can be accessed directly using a separate interface of the data environment, without accessing the control plane.

摘要： A computer-implemented data processing system and method for storing a data set at a plurality of data centers. The data centers and hosts within the data centers may, for example, be organized according to a multi-tiered ring arrangement. A hashing arrangement may be used to implement the ring arrangement to select the data centers and hosts where the writing and reading of the data sets occurs, version histories may also be written and read at the hosts and may be used to evaluate causal relationships between the data sets after the reading occurs.

摘要： Methods and systems for processing data requests in a client-server computing environment, such as the Web, are disclosed. A client device initially transmits a data request to a randomly selected first server device. The first server device may reject the data request if its request queue threshold is exceeded. The client device retransmits the data request, including the request queue threshold, to a randomly selected second server device. The second server device may reject the data request if the request queue threshold of the first server device is smaller than a request queue threshold of the second server device. The client device transmits the data request back to the first server device, including the request queue threshold of the second server device. The first server device processes the data request and adjusts its request queue threshold based on the request queue thresholds of the first and second server devices.

摘要： 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.
