Abstract: According to one or more aspects, apparatus, systems, and methods may be provided for language agnostic full link gray deployment of microservices and middleware. According to an aspect a method may be provided for propagating and routing traffic between microservices of an application. The method includes receiving, at a plugin of a proxy corresponding to a service of the application, an outbound request from the service. The outbound request may indicate a trace identifier (ID) identifying a trace of the outbound request in the application. The method may further include assigning, by the plugin, a custom label to the outbound request. The custom label may be associated with the trace ID and indicate a version of the application towards which the outbound request is to be routed. The method may further include sending, by the plugin to a router of the proxy, the outbound request for routing.

Abstract: A method, system, and computer-readable medium for enabling a client application to access an online service, such as an online AI service, without requiring the developer of the client application to fully understand the interface contract of the online service and write software code integrating the client application directly with the interface of the online service. In one aspect, the interface contract of the online service is automatically analyzed, and the client application developer is presented with options for configuring the mapping of data fields between the client application or client application database and the online service. Based on the developer's configuration choices, software code is automatically generated for exchanging data between the client application or client application database and the online service. Trigger conditions for the software code may be changes in the database state, predefined events, or requests received from the client application.
