Abstract: Techniques for detection of the fraudulent use of content delivery network (CDN) served byte streams are described. A fraud detection service obtains CDN log data, distribution data, and account data and uses elements therefrom to perform a distribution-centric fraud analysis using machine learning techniques. Based on the likelihood of fraud determined by the analysis, the fraud detection service can rapidly perform actions to address the fraud, such as the termination of service for the distribution, throttling of resources provided for the distribution, or further investigation techniques.

Abstract: A cache system may maintain size and/or request rate metrics for objects in a lower level cache and for objects in a higher level cache. When an L1 cache does not have an object, it requests the object from an L2 cache and sends to the L2 cache aggregate size and request rate metrics for objects in the L1 cache. The L2 cache may obtain a size metric and a request rate metric for the requested object and then determine, based on the aggregate size and request rate metrics for the objects in the L1 cache and the size metric and the request rate metric for the requested object in the L2 cache, an indication of whether or not the L1 cache should cache the requested object. The L2 cache provides the object and the indication to the L1 cache.

Abstract: Systems and method with regard to the routing of a client computing device DNS query within a content delivery network service provider domain as a function of additional request routing information embedded as parameters in messages transmitted as part of the DNS queries generated by, or on behalf of, the client computing device are provided. By parsing and processing all the received information, the CDN service provider may select components of a CDN network reflective of the additional request routing information.

Abstract: Edge functions at an edge location of a content delivery network (CDN) may access data from a back-end database without the need to make high-latency network calls to the back-end databases. When a client sends a query to the edge location, an edge function is triggered. The requested data may be retrieved from a read-only local table at the edge location (populated from a back-end database) and the retrieved data is provided to the edge function's memory for low-latency access during function execution.

Abstract: A determination is made that a request associated with an application is a candidate for blockchain-based deferral. An insertion of a record representing at least the request at a blockchain is initiated. One or more records representing the request are accessed to perform an operation indicated in the request.

Abstract: Described are techniques for determining a confidence value associated with the probability that a user will access a particular second user interface by interacting with a first user interface. The confidence value may be determined based on user interaction data indicative of prior interactions by the user. Based on the confidence value, the second user interface may be pre-generated, in advance of user interaction with the first user interface. If the user interacts with the first user interface in a manner that would cause presentation of the second user interface, the user may be provided with the second user interface promptly, avoiding the latency that would normally be experienced during the time that the second user interface is generated. Pre-generation of only the user interfaces indicated by the user interaction data may limit unnecessary use of computing resources.

Abstract: In some embodiments, a system is provided, and computer-executable instructions cause the system to: obtain, at an edge server of a content delivery network, a request for a content item from a client device; determine that the there are multiple versions of the first content item that require varying amount of resources to serve including a first version, and a second version requiring more resources to serve than the first version; select the second version; send the second version; determine that the client device is not properly rendering the second version of the content item; and in response to determining that that the client device is not properly rendering the second version, send the first version.

Abstract: Techniques for using one or more satellites as a part of a content delivery network are described. For example, in some instances a satellite of a cluster of satellites is to receive a request for a resource hosted by the content delivery network; determine that the request for the resource cannot be served by the cluster of satellites; determine a first entity to ask for the resource; send a secondary request for the resource to the determined first entity; receive the resource from the determined first entity; and respond, to a user of the content delivery network, to the request using the received resource for the resource.

Abstract: A centralized content management service may facilitate streaming providers obtaining rights to digital content associated with content providers. The content management service may maintain a site in which the content providers and streaming providers may negotiate for rights to digital content items. Upon receiving a request from a streaming provider to stream a digital content item to a customer, the content management service may authenticate the customer and validate the streaming provider to confirm that the streaming provider is authorized to stream the digital content item to the customer. The digital content item may be encrypted, decrypted, and re-encrypted prior using various encryption keys prior to streaming the digital content item to the customer. The content management service may cause the digital content item to be streamed to a customer device of the customer without providing a copy of the digital content item to the streaming provider.

Abstract: A content delivery system dynamically manages a content cache fleet by expanding or shrinking the size of the cache fleet to anticipate and/or respond to changes in demand for cached content. The content delivery system can consider various demand-based parameters when determining when and how to scale the cache fleet, including the overall demand (expected or observed) for all content available for delivery by the content delivery system, the demand for a subset of content or individual content items relative to the demand for other subsets of content or individual content items, etc. When content servers are removed from the cache fleet, snapshots of the content caches of the content servers can be stored to a persistent data store, and then restored to content servers when content servers are added to the cache fleet.
