Abstract: An enterprise database server may store enterprise information. An application layer server, coupled to the enterprise database server, may use an application programming language (e.g., ABAP) to access the enterprise information. The application layer server may execute a plurality of domain runtimes, each associated with a domain service (e.g., transactional, SQL, analytical, search, etc.). The application layer server may also access, by a first domain runtime, a first data service entity in an infrastructure for data modelling (e.g., CDS) that enables data models to be defined and consumed on the enterprise database server. Similarly, the application layer server may access, by a second domain runtime, a second data service entity in the infrastructure for data modelling. According to some embodiments, the first data service entity includes a first provider contract and the second data service entity includes a second provider contract (different than the first provider contract).

Abstract: Techniques are disclosed for creating an attachment between two compute instances. An infrastructure and a generalized method is described for attaching two or more cloud resources (e.g., two compute instances) in spite of the compute resources being provisioned by two different services from different cloud tenancies. An automated process is described that is executed for wiring the compute instances. The automated process can be generally applied to attach any two compute instances providing two different services and provisioned from two different service tenancies.

In some examples, a method can include, in response to a first request to run a serverless function, executing, at an execution environment on a network, computer-readable code configured to perform the serverless function; after the computer-readable code has executed, modifying a pointer to an area of memory used to store a first state of the serverless function to reference a different area of memory; in response to a second request to run the serverless function, reusing, at the execution environment, the computer-readable code to perform the serverless function; and based on the pointer referencing the different area of memory, using the different area of memory to store a second state of the serverless function.

Abstract: A method and system for cloud distributed hybrid data storage and normalization are disclosed. The method may include obtaining a data set comprising data entities. A data entity may comprise data fields each containing a data element. The method may further include determining policy constraint meta-data for each of the data elements based on the storage policy constraint. The policy constraint meta-data may include a first meta-tag indicating the storage policy constraint for the data element. The method may further include determining whether a server satisfies the storage policy constraint based on the first meta-tag for the data element. When the server satisfies the storage policy constraint, the method may further include transmitting the data element to the server to store the data element on the server. When the server fails to satisfy the storage policy constraint, the method may further include, storing the data element on the client.

Abstract: In a data sharing system 1, a plurality of dHCI systems 100 share data by communication, and each of the plurality of dHCI systems 100 is configured to include a dHCI 110 to provide a virtual environment to execute an application and a storage system 120 to provide a volume to the virtual environment together with a storage device of the dHCI 110. Each of the plurality of dHCI systems 100 stores data of the own computer system in the volume of the own computer system and acquires data of another computer system from the other computer system and stores the data in the volume. When data of some other computer system cannot be acquired from the other computer system, each of the plurality of dHCI systems 100 acquires the data from a different other computer system and stores the data in the volume.

Abstract: This application provides a packet processing method and a device. In this application, a control identifier field is added to a packet, and the control identifier field indicates whether forwarding of the packet is allowed when a resource corresponding to a slice identifier fails to be matched. The control identifier field and a slice identifier of a network slice are carried in the packet, so that the slice identifier and the control identifier field are transmitted on a network together. When a receive end fails to match the resource corresponding to the slice identifier, the receive end can discard the packet based on the control identifier field, instead of forwarding the packet by using routing information.

Abstract: A method for a proxyless protocol includes intercepting, from a client, a first Transmission Control Protocol (TCP) connection request requesting to establish a TCP connection between the client and a proxy for routing data to a destination server. The request includes client information and a first sequence number. The method also includes transmitting, to the destination server, a second TCP connection request to establish a TCP connection between the client and the destination server. The second request includes a second sequence number less than the first sequence number. The method also includes intercepting, from the destination server, an acknowledgment message indicating acknowledgment of the second TCP connection request. The method also includes transmitting, to the destination server, a proxy protocol header message with the client information.

Abstract: A system and method for managing logs from computing environments uses a rate change in a rate of occurrence of same event type logs from a base time window to a current time window for each of the event types to identify candidate event types for a particular tier log storage. The rate changes of the event types are checked against a threshold rate change range to identify the candidate event types. In response to selection of some of the candidate event types, the logs in the selected candidate event types are transferred to the particular tier log storage.

The system may generate aggregated resource data based on a corresponding quantity of each resource within the resource class and may determine, based on the aggregated resource data, a resource usage metric indicating a total amount of resources used by the cloud computing system.

Abstract: Systems, methods, and computer-readable media for reducing distributed storage operation latency using segment routing. In some examples, a method can involve receiving, from a client, a message identifying an intent to store or retrieve data on a distributed storage environment, and sending to the client a segment routing (SR) list identifying storage node candidates for storing or retrieving the data. The method can involve steering a data request from the client through a path defined by the SR list based on a segment routing header (SRH) associated with the request, the SRH being configured to steer the request through the path until a storage node from the storage node candidates accepts the request. The method can further involve sending, to the client device, a response indicating that the storage node has accepted the request and storing or retrieving the data at the storage node that accepted the request.
