16.2 FX Logical Nodes Remain Distinct from Runtime Deployments

Go To FX Demo Logical Rules and Constraints

An FX logical Node represents a platform-independent participant in the FX Demo Logical Profile. It does not represent a process, service, container, pod, virtual machine, serverless function, thread, task, library, subroutine, RPC endpoint, REST resource, DDS participant, or deployment artefact.

Implementation profiles select execution mechanisms that realise FX logical Nodes. Deployment profiles then describe how those implementation artefacts run in a concrete environment.

A single runtime artefact implements several FX logical Nodes when the selected implementation approach combines responsibilities. Several runtime artefacts implement one FX logical Node when the selected implementation approach distributes responsibility. Neither choice redefines the FX logical Node.
