1. A system for an ontology-based request/reply service (RRS), comprising: a storage which is configured to store an RRS ontology; and a processor cooperatively operable with the storage, and configured to: host a plurality of different request/reply services (RRS), each different RRS is dedicated to represent a different unique service and to provide connections from a client to a server instance of the different unique service, each different RRS is accessible by client instances and server instances through a same independent communication layer (ICL) that handles different transport protocols between different platforms; receive, from the client through the ICL, a request that indicates a unique service and determine which RRS of the different RRSs is dedicated to represent the unique service which is indicated in the request; instantiate an RRS of the different RRSs dynamically as needed, the RRS being instantiated according to an individual RRS ontology stored in the RRS ontology, wherein the individual RRS ontology provides a syntactical and semantical framework to establish processing which is dedicated to represent the unique service; route the request which is received to the instantiated RRS of the different RRSs which is determined to be dedicated to represent the unique service which is indicated in the request, and then route the request through a server instance corresponding to the unique service indicated in the request, to process the request and to return, to the client, a response to satisfy the request; and manage transport connectivity and mutual communication between a plurality of clients and the plurality of different RRSs, mutual communication between the plurality of different RRSs, and mutual communication between the plurality of different RRSs and a plurality of server instances.
