Abstract: Systems and methods are described for implementing a multi-tenant caching service. The multi-tenant caching service provides a scalable infrastructure with dedicated per-tenant cache widths for tenants of a hosted computing environment, and allows tenants to implement a caching layer between cloud-based services that would otherwise need to scale up in response to load. Tenants may also use the service as a public facing endpoint that caches content provided by backend servers. Content provided by the tenants may be distributed and cached across a cell-based architecture, each cell of which may include a set of storage volumes that are partitioned into caches for individual tenants and configured to store a portion of the content provided by that tenant. Eviction policies may be implemented based on tenant cache usage across multiple cells, and geolocation policies may be implemented to ensure that cached content remains within a particular geographic region.

Abstract: Techniques for dynamic content delivery network (CDN) selection using the domain name service (DNS) protocol are described. A DNS resolver utilizes a network identifier provided within a DNS query seeking to resolve a domain to select between different CDNs. The selection can be based on an analysis of network metric summary data corresponding to the CDNs from the perspective of an approximate location of the requesting client, as determined via the network identifier as a proxy. The selection process and involved network metric types can be configured by the user associated with the domain via a selection policy. Network metrics can be provided by the user or collected based on reported data generated by remote clients through provided metric-generating code, and thereafter transformed into network metric summary data that is used for resolution.

Abstract: A datastore engine at an edge location of a content delivery network (CDN) may perform low-latency query processing and data retrieval for multiple types of databases at one or more origin servers. When a client sends a query to the edge location, the datastore engine translates the query from a back-end database format into a native format of the local edge datastore. If the requested data is not there, then the datastore engine retrieves the data from the back-end table and inserted inserts the data into the local edge datastore. By using multiple queries over time to re-construct data from the backend database tables at the edge, the datastore engine may provide low-latency access to data from the backend database tables (avoiding the need to retrieve data from the back-end tables to serve subsequent queries).

Abstract: Various embodiments of apparatuses and methods for protecting data integrity in a content distribution network (“CDN”) are described. Code or data in one of the servers or instances of a CDN might sometimes become incorrect or corrupt. One corrupted server or instance can potentially impact a considerable portion of the CDN. To solve these and other problems, various embodiments of a CDN can designate one or more parameters, which are then identified in a request for content to another entity. In these embodiments, the CDN can generate an encoding of the expected values of the designated parameters. The CDN can then compare, in these embodiments, its encoding of the expected values to an encoding of the values received from the other entity in response to the request. The CDN can validate the content of the response, as well as the identity of the other entity, in some embodiments.

Abstract: Techniques for stateful computing at the edge of a content delivery network are described. In some embodiments, a point of presence of the content delivery network includes proxy servers, function execution units, and function state cache servers executing on computer systems within the point of presence. A proxy server checks for requests for resources hosted on behalf of customers of the content delivery network that trigger a customer-specified function. When a function is triggered, the proxy server selects an execution unit and sends a function execution request to the execution unit. The execution unit executes functions of many different customers of the provider network. Upon receiving a request to execute a function that is stateful, the execution unit retrieves the function state from a function state cache server, execute the function, and returns a result to the proxy server.

Abstract: System and methods are provided for sharding at the content level and routing content requests. Each point of presence (PoP) can initially identify the PoP that should serve content by using hashing. A PoP can encode a domain name with the identified PoP in metadata and redirect the client computing device. A client computing device transmits a DNS query for the encoded domain name. A DNS server receives the encoded domain name and decrypts and decodes the domain name label. The DNS server uses the decrypted and decoded metadata to make a further routing decision. The DNS server sends, to the client computing device, a DNS reply with the Internet Protocol (IP) address of the selected PoP. The client computing device requests content from the PoP identified by the provided IP address.

Abstract: Techniques for using a satellite as a part of a content delivery network are described. For example, in some instances a satellite 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 satellite, 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, respond, to a user of the content delivery network, to the request using the received resource for the resource, and respond to a subsequent request using the cached received resource.

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.
