Disclosed is a system for automatically executing multiple functional units of operation from multiple applications to complete a task that requires data from a variety of sources. The system stores information about operations that may be executed on a client device. When executing a sequence of operations, for example in response to a user request, the system may automatically store output from each operation. When executing subsequent operations in the sequence of operations, the system can determine whether output from a previously executed operation is appropriate for use as input to a new operation. The system can thus save data from one application and automatically use that data as input to a different application. Additionally, the system may determine subsequent operations to execute in response to previously observed output values.

A global queue service of a provider network allows clients to automatically replicate a queue to another queue of one or more other regions (creating a global queue). A local instance of the service receives a send request from a producer. In response, the local instance stores a message in a local queue and replicates the send request to a remote queue of a remote instance of the global queue service (e.g., at another region). The local instance receives a receive request from a consumer and sends the message to the consumer (without replicating the request to the remote queue). The local instance then receives a delete request from a consumer. In response, the local instance deletes the message from the local queue and replicates the delete request to the remote queue. The local instance also receives replicated requests from the remote instance and in response, applies them locally.

Provided is a distributed ledger device, aiming at easily and appropriately determining a status of operational processing on a distributed ledger in a certain distributed ledger device at another distributed ledger device. A BC node in a BC system including a plurality of BC nodes that manage a distributed ledger for a predetermined target transaction, the BC node including: the storage device; and the processor, in which the storage device stores the distributed ledger, and the processor, when executing processing relating to the distributed ledger, transmits content information indicating contents of the processing to be managed by another BC node that manages the distributed ledger. The processor may transmit an instruction to register the content information in another distributed ledger managed by the plurality of BC nodes that manage the distributed ledger.

A service may be provided that reads sensors, and that communicates information based on the sensor readings to applications. In one example, an operating system provides a sensor interface that allows programs that run on a machine to read the values of sensors (such as an accelerometer, light meter, etc.). A service may use the interface to read the value of sensors, and may receive subscriptions to sensor values from other programs. The service may then generate messages that contain the sensor value, and may provide these messages to programs that have subscribed to the messages. The messages may contain raw sensor data. Or, the messages may contain information that is derived from the sensor data and/or from other data.

A computer system hosting (micro)services that uses a service mesh to govern communication between the services. The services include consumer services and an event stream service, the latter directing an event stream from a producer service to the individual consumer services. The control plane of the service mesh has the role of creating and removing service instances. Based on a specified event capacity that is to be provided by the consumer services collectively, the control plane manages service provisioning by estimating the current event capacity of the system. This is done by measuring the event capacities of each consumer service instance and summing them, from which any shortfall or excess of the current event capacity in relation to the specified event capacity can be determined. Consumer service instances are then added in case of a shortfall or removed in case of an excess as needed to avoid over or under-provisioning.

Techniques and systems are provided for processing user interface content. For example, a server computer can receive a user interface event corresponding to a user interface of a device (e.g., a client device, another server computer, or other device). An application associated with the user interface event can be determined, and an interface model 5 can be generated using the application associated with the user interface event. The interface model defines state information for one or more graphic objects of the user interface. The state information results from the user interface event. The server computer can send the interface model to the device, which enables the device to render the user interface.

This application provides a graphics rendering method and apparatus. A service starts an application and obtains a rendering instruction sent by the application; and sends the rendering instruction to an electronic device. The electronic device performs graphics rendering according to the rendering instruction, to display an image related to the application. According to the technical solutions provided in this application, the electronic device, instead of the server, can perform graphics rendering according to the rendering instruction, thereby improving picture quality and user experience.

A automation system, a computer and method for communicating includes exchanging data, between a first computer, a second computer and at least one automation device over a wide area network via an application-specific protocol, wherein one of the computers has a local network connection to the automation device, the application-specific protocol has an application layer, and the first and second computers execute respective first and second automation programs such that a transparent connection is provided for the automation programs and their application-specific protocol beyond local network boundaries which can be it efficiently, where signaling functions from lower communication layers that are missing are simulated by introducing event loops on both sides of the communication.

A method and system is provided for data/process sharing. A trigger response unit is provided to reside on a first system where a first application system is present. The trigger response unit monitors, on the first system, when trigger data from a second application system is presented in the first application system. When the trigger data is presented in the first application system, the trigger response unit decodes the trigger data to obtain a trigger corresponding to a second application system. The obtained trigger is used to launch the second application system on the first system.

Methods and apparatus to provide peer-to-peer interrupt signaling between devices coupled via one or more interconnects are described. In one embodiment, a NIC (Network Interface Card such as a Remote Direct Memory Access (RDMA) capable NIC) transfers data directly into or out of the memory of a peer device that is coupled to the NIC via one or more interconnects, bypassing a host computing/processing unit and/or main system memory. Other embodiments are also disclosed.
