Abstract: An on-demand code execution environment present in points of presence (POPs) and in regions serviced by the POPs is provided herein. For example, a POP may receive a request to execute a task associated with user-defined code. If the POP determines that the computing resources necessary to execute a received task are not available or that the POP should not execute the received task for another reason (e.g., the task is not commonly received and the computing resources needed to execute the task are therefore best allocated for other requests), the POP can forward the task to a region that the POP services for execution by an on-demand code execution environment present in the region. The on-demand code execution environment present in the region can execute the task and forward the results of the execution to the POP for distribution back to a user device that requested the task execution.

Abstract: Systems and methods for sloppy routing are provided. A client transmits a DNS query corresponding to a requested resource to a content delivery network (CDN) service provider. In some embodiments, the CDN service provider processes the DNS query to determine whether a threshold content delivery bandwidth has been exceeded by data links at cache servers. In other embodiments, additionally or alternatively, the CDN service provider determines whether a content provider has exceeded a threshold network usage that indicates a price at which the CDN service provider to provide content on behalf of the content provider. Using both or either of these thresholds, the CDN service provider can further process the DNS query by providing an alternative resource identifier or a cache IP address, both associated with an alternative POP. In some embodiments, the CDN service provider determines a routing mode for the response to the DNS query.

If the POP determines that the computing resources necessary to execute a received task are not available or that the POP should not execute the received task for another reason (e.g., the task is not commonly received and the computing resources needed to execute the task are therefore best allocated for other requests), the POP can identify a region suitable for executing the task and forward the task to the identified region. An on-demand code execution environment present in the identified region can execute the task and forward the results of the execution to the POP for distribution back to a user device that requested the task execution.

Abstract: Systems and methods are described that enable the mitigation of network attacks directed to specific sets of content on a content delivery system. A set of content targeted in the attack may be identified based at least in part on a combination of network addresses to which attacked-related packets are transmitted. Thereafter, the content delivery system may mitigate the attack based on the identified target. For example, where both targeted and non-targeted sets of content are associated with the attacked network addresses, traffic directed to these sets of content may be separated, e.g., in order to reduce the impact of the attack on the non-targeted sets of content or increase the computing resources available to the targeted content. Redirection of traffic may occur using either or both of resolution-based redirection or routing-based redirection.

Abstract: Methods, systems, and computer-readable media for customizable event-triggered computation at edge locations are disclosed. A request for content is received at an edge server from a client device. The content is sought from a content cache at the edge server or from an origin server coupled to the edge server. Processing of the request is initiated, comprising encountering an event. The event is associated with a function specified by a customer. The function associated with the event is executed at the edge server using process isolation. The content is generated based at least in part on execution of the function. The content is sent from the edge server to the client device.

Abstract: An edge system receives requests from user devices to retrieves files from an origin server. Instead of retrieving the files as fast as possible, the edge system throttles the retrieval of files to a rate that just exceeds the speed at which the file is played by a browser or media player. The edge system determines an appropriate retrieval rate based on the contents of the file itself. For example, a manifest file associated with the file can indicate a time it takes to play back content and a bitrate of the content. Thus, the edge server can use this information to retrieve a file from an origin server at a rate that is just fast enough to minimize playback interruption. The retrieval rate determined by the edge server therefore does not rely on how fast or slow the user device retrieves the file from the edge server.

Abstract: An origin server that is implemented within one or more devices within a third party virtual private cloud (VPC) is provided herein. Instead of communicating with various CDNs over a public network, the third party VPC may instead communicate with a managed VPC via a private network. Thus, no gateway, network address translation (NAT), or other such devices may be needed for the third party VPC and the managed VPC to communicate. Rather, a VPC identifier of the managed VPC and a VPC identifier of the third party VPC are used to pair the two VPCs. Once paired, a private route is set up such that points from the private address space of the third party VPC to the private address space of the managed VPC. The managed VPC then communicates directly with the various CDNs via a public network.
