Abstract: Disclosed embodiments are directed at systems, methods, and architecture for providing execution order and execution for plugins installed on an API gateway associated with a microservices application. In application architectures where features of microservices are implemented as plugins and migrated to an API gateway, the relevant APIs are able to be built lighter weight than otherwise. However, the migration of the features to plugins introduces the potential for error states in the microservice application. To resolve the potential issues, the API gateway takes into consideration a set of native instructions in each of the plugins to determine the execution order thereof. The execution order is determined dynamically in response to requests by the APIs of the microservice application.

Abstract: Inter-microservice communications are managed through in-memory connection routing. A sending microservice writes a message over a port associated with the connection. The message is routed directly to one or more receiving microservices associated with the connection over their ports associated with the connection. The message may be converted to a different format or multiple different formats through plugins processed when the message is received over the sending microservice's port and before the converting messages are routed over the receiving microservices' ports. The inter-microservice communications are hardware and platform independent or agnostic, such that the microservices associated with the connection can be processed on different hardware and different platforms from one another.

Abstract: The present disclosure involves systems, software, and computer implemented methods for resolving data location for queries in a multi-system instance landscape. One example method includes receiving a request for data for at least one entity that includes a qualified identifier that includes a system tenant qualifier and a local identifier. The system tenant qualifier identifies a system tenant in a multi-system tenant landscape and the local identifier identifies an entity instance of an entity in the system tenant. A routing policy table configured for the multi-system tenant landscape is identified and a cell is located in the routing policy table that corresponds to the entity and the system tenant. A routing policy is determined for routing the request based on the cell. The routing policy is used to determine a target system tenant to which to route the request and the request is provided to the target system tenant.

Abstract: Disclosed herein are embodiments of systems, methods, and products comprises a server for efficiently processing electronic requests. The server receives a plurality of predictive computer models and a specification file for each model for registration. The server extracts validation codes for each model based on the specification file. When the server receives an electronic request, the API layer of the server validates the request by verifying the inputs of the request satisfying the validation codes of the corresponding model. If the electronic request is invalid, the server returns an error message immediately; otherwise, the API layer of the server sends the electronic request to the model execution layer. Within the model execution layer, the server executes the corresponding model based on the request inputs and generates output results. The model execution layer transmits the output results back to the API layer, which transmits the output results to the user device.

Abstract: Using a common reference address when processing calls among a native ABI and a foreign ABI. Based on caller calling using a reference address, a lookup structure is used to determine whether the reference address is within a memory range storing native code (and that the callee is native) or a memory range not storing native code (and that the callee is foreign). Execution of the callee is initiated based on one of (i) when the caller is native and when the callee is foreign, calling the callee using the reference address within an emulator; (ii) when the caller is foreign and the callee is native, calling an entry thunk; (iii) when the caller is native and the callee is foreign, calling an exit thunk; or (iv) when the caller is native and the callee is native, directly calling the callee using the reference address.

In a data sending process, the one or more applications distribute data to corresponding paths through a system call.

Abstract: In an embodiment, an operating system for a computer system includes a kernel that assigns code sequences to execute on various processors. The kernel itself may execute on a processor as well. Specifically, in one embodiment, the kernel may execute on a processor with a relatively low instructions per clock (IPC) design. At least a portion of other processors in the system may have higher IPC designs, and processors with higher IPC designs may be used to execute some of the code sequences. A given code sequence executing on a processor may queue multiple messages to other code sequences, which the kernel may asynchronously read and schedule the targeted code sequences for execution in response to the messages. Rather than synchronously preparing a message and making a call to send the message, the executing code sequences may continue executing and queuing messages until the code has completed or is in need of a result from one of the messages.

The first schema may include data describing content of the first message and organization of the content of the first message. An asynchronous API document may be generated based at least in part on the first schema and the first metadata.

In an example two computing nodes coordinate to provide a computing service, where each node has a base operating system configured to fence the other base operating system, and an application configured to fence the other application. In some examples, fencing requests by an application are routed through its base operating system, which coordinates application-level fencing requests and operating system-level fencing requests.

Abstract: The present disclosure relates to controlling communication between various applications or integrating various applications using interaction patterns. Interaction pattern data, which defines multiple roles for an interaction pattern is generated. Each role is associated with a transaction and is a source or target of a transaction. A transaction is performed using an application programming interface (API). A role can be a provider, or a consumer of the API based on whether the role is a source or target of the transaction. Application conformance data, which defines a set of roles implemented by the application is generated. An application is permitted to invoke an API of another application, if the application implements a first role and the other application implements a second role, and the first role and the second role are a source and target, respectively, of a transaction performed using the API.
