Abstract: Methods, systems, and devices supporting global message threads are described. A thread server may receive a communication message associated with a first set of user identifiers (e.g., the author and recipients of the message) and may extract a thread identifier from the message. The thread identifier may associate the message with one or more additional messages (e.g., from the same thread of messages), where the one or more additional messages may be associated with different user identifiers. The thread server may upsert the received communication message to a stored set of messages associated with a root indicating the thread identifier. If the thread server receives a query indicating the thread identifier from a user, the thread server may retrieve all of the messages associated with the thread identifier from persistent memory based on the query, including messages that are not associated with the user identifier for the querying user.

Abstract: Techniques are described that enable a user to upgrade a stack of resources by providing a template that reflects the desired end state of the stack. Upon receiving a new template, the system automatically detects changes that should be performed and determines the order in which the changes should be performed. The system can also detect if the desired changes to the stack are a result of direct modifications; because parameters to the resources have changed; or the changes are indirectly caused by other dependency/attribute changing. Additionally, the system determines whether the changes require creating new resources or if the changes can be made to the resources live. In case of replacement of resources, the system will first create the new resource, move that new resource into the stack and remove the old resource(s). In case of failures, the system ensures that the stack rolls back to the initial state.

Abstract: A storage gateway serves as an interface between processes on a customer network and a service provider. The storage gateway is located on-premise with the customer processes. To customer processes, it appears that data is stored locally. However, the storage gateway interfaces with a remote storage service to store the data. For cached gateways, the primary data store is a remote data store, while frequently accessed data may be locally cached by the gateway. Reads may be satisfied from the local cache or from virtual data storage; writes are handled so as to appropriately update data blocks in the local cache and/or in virtual data storage. For shadowing gateways, the primary data store is the local data store; reads are passed through to a local data store, and writes are shadowed to virtual data storage as well as being sent to local data store.

Abstract: Systems and methods for locating server nodes for edge devices using latency-based georouting. At least one cloud platform including at least one cloud platform router and a node database is in network communication with at least one edge device and a plurality of server nodes. The at least one cloud platform receives an initial hypertext transfer protocol (HTTP) request from the at least one edge device. The node database is queried using the at least one cloud platform router and node data is fetched from the plurality of server nodes using an object-oriented function. A query result is returned indicating a nearest node from the plurality of server nodes. The HTTP request is responded to with a unique hypertext markup language (HTML) web page, and the HTTP request is executed using the nearest node.

Abstract: A triggered action set for a first device can be defined by the first device. Instructions for executing the triggered action set can be provided by the first device to a second device. Subsequent to providing the instructions, the first device can monitor the status of the second device; if the delegate device enters a state in which it is presumed to be unavailable to execute the trigger, the first device can monitor for a triggering event associated with the triggered action set and send a control message to an accessory device in response to detecting the triggering event.

Abstract: Computer system and method for managing storage requests in a distributed storage system uses congestion signals associated with storage requests, which are generated based on congestion at local storage of the computer system that supports a virtual storage area network. The storage requests are differentiated between a first class of storage requests and at least one other class of storage requests. For a storage request of the first class of storage requests, an actual ratio of a current average bandwidth of the first class of storage requests to a current average bandwidth of a second class of storage requests is calculated and compared with an expected ratio. The congestion signal associated with the storage request is then adjusted and transmitted to at least one source of storage requests for storage request fairness control.

Abstract: Described herein are systems and methods for content streaming with bandwidth management. Prior to shipment of a streaming device, partial content and remaining content from content may be generated. The partial content may be configured to be unusable for presentation at the streaming device without at least a portion of the remaining content, and the remaining content may be configured to be unusable for presentation at the streaming device without at least a portion of the partial content. The partial content may be combinable with the remaining content by the streaming device to form a presentable file corresponding to the first content. The partial content may have a filename extension indicating that an associated media file includes the partial content, and the associated media file is different from the presentable file. The partial content on the streaming device may be stored prior to the shipment of the streaming device.
