Examples disclosed herein relate to using a tenant data mapping for multiple tenant cloud applications. For example, a processor executing tenant access instructions may retrieve data related to a tenant associated with a user login and data related to tenants with a hierarchical relationship to the tenant and create a mapping including the retrieved data. The data may be wherein data is communicated via the mapping such that cloud application instructions are related to a single tenant application

This disclosure relates to systems and methods for collecting, integrating, processing, distributing, and analyzing spatial and/or spatio-temporal information associated with a variety of data sources and/or locations. In some embodiments, systems and methods described herein allow for collection and integration of information included in one or more spatial and/or spatio-temporal data streams and/or other related information that may be utilized in connection with one or more analytical processes. In certain embodiments, the disclosed embodiments may allow a user to, among other things, interact with spatio-temporal information associated with a variety of diverse data sources, generate visualizations using such data, and/or perform desired analytical queries based on the data.

Maintaining cache coherency in the presence of a network attached memory is disclosed. A computer system includes a plurality of physical nodes. An operating system is run collectively across the plurality of physical nodes. The physical nodes are configured to communicate with a network attached memory. Based at least in part on an operation to be performed with respect to page on a first physical node included in the plurality of physical nodes, the network attached memory is configured to receive a message. The network attached memory is configured to perform an action based at least in part on the received message.

A system and method are provided of minimizing network bandwidth used from an external network by client peers in a local network. The method can include the operation of organizing a plurality of clients each having media streamlets and a client parent in a structure within the local network. Mapping information propagates through the structure. The mapping information represents local streamlet locations as stored by the plurality of clients. Another operation is retrieving a local streamlet from a client identified in the mapping information as having the local streamlet for the requesting client.

Described herein are systems, devices, and methods for content delivery on the Internet. In certain non-limiting embodiments, a caching model is provided that can support caching for indefinite time periods, potentially with infinite or relatively long time-to-live values, yet provide prompt updates when the underlying origin content changes. In one approach, an origin server can annotate its responses to content requests with tokens, e.g., placing them in an appended HTTP header or otherwise. The tokens can drive the process of caching, and can be used as handles for later invalidating the responses within caching proxy servers delivering the content. This caching and invalidation model can be extended out to clients, such that clients may be notified of invalid data and obtain timely updates.

A method for managing a cache memory network according to a distributed hierarchical cache model is disclosed. The distributed hierarchical cache model includes a plurality of cache levels each corresponding to a delivery rank for delivering data content to users of the cache memory network. The method includes dividing at least one cache memory of the cache memory network into a plurality of cache segments, mapping each of the cache segments to a cache level of the distributed hierarchical cache model, and performing cache management operations over the cache memory network according to the distributed hierarchical cache model.

A slave resource router may receive a client request. The slave resource router may be the nearest representation of an Anycast IP address in a network to a client sending the client request in the network. The slave resource router may then determine that the slave resource router has been authorized to cache content for a delivery service corresponding to the client request. Next, the slave resource router may determine that content corresponding to the client request is cached locally in a blind cache. Then the slave resource router may provide the client with the content from the blind cache.

Technologies for fulfilling service requests in an edge architecture include an edge gateway device to receive a request from an edge device or an intermediate tier device of an edge network to perform a function of a service by an entity hosting the service. The edge gateway device is to identify one or more input data to fulfill the request by the service and request the one or more input data from an edge resource identified to provide the input data. The edge gateway device is to provide the input data to the entity associated with the request.
