====== Real-World Node ====== [[dido:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]] ===== Discussion ===== A [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]] may represent an actual operational system or may be represented through a virtual, simulated, emulated, or other realization used for testing. A Real-World Node identifies the actual Node, system, device, service, or environment that exists outside the representation used by a test or simulation. The term does not require the Node to be implemented solely using physical hardware. A real-world operational Node may itself use virtual machines, containers, cloud services, software-defined infrastructure, or other implementation technologies. A [[dido:99_annexes:annex-b-terms-and-definitions:t:twin_realization|Twin Realization]] may represent, observe, interact with, or otherwise correspond to a Real-World Node. ===== Definition ===== //a Node realized by the actual system, device, service, or environment represented or exercised during testing// ===== Source ===== Derived from DIDO-TE source material distinguishing virtual Twin Nodes and real-world or physical Nodes participating in distributed testing. ===== Note ===== “Real-world” distinguishes the actual participating or represented Node from a virtual, simulated, emulated, or other test representation. It does not imply that every component of the Node is implemented directly in physical hardware. ===== Example ===== A production service operating in a remote facility may participate in a Test Environment as a Real-World Node while a Twin Realization represents that service within another portion of the test. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
