Abstract: Aspects extend to methods, systems, and computer program products for orchestrating operations at applications. Aspects of the invention use a side channel (instrumentation messages generated by a service) as a mechanism to discover when a service has completed an activity. Use of a side channel, allows a (e.g., client) application to create behaviors similar to service side interfaces and/or protocols without modifying a service. Accordingly, functionality can be added incrementally, safely, and cheaply without having to revise an underlying implementation. In one aspect, an instrumentation collector and publisher (ICP) facilitates the synchronization between services and an application. ICP is a scalable infrastructure that provides applications a way to interact with servers through instrumentation.

Abstract: Runtime polymorphism may be enabled with metadata that is usable for casting objects to casted objects. In an exemplary media implementation, processor-executable instructions cause operations including: discover at least one type of an object while in a runtime environment; and create a casted object from the object by casting the object to the casted object using metadata. An exemplary computing device implementation includes: one or more processors; and one or more media in operative communication therewith, the one or more media including: an object of a first type; metadata that is capable of being used to cast unknown objects in a runtime environment; and processor-executable instructions that, when executed, cause the one or more processors to perform an action including: casting the object of the first type to a casted object of a second type using the metadata in the runtime environment, the first type differing from the second type.
