When TOSCA cannot be consumed by a particular site directly, Domino Server can utilize existing translators (e.g., heat-translator) to first translate the template before delivery. +Internal Processing Pipeline at Domino Server +--------------------------------------------- + +:numref:`fig-pipe` shows the block diagram for the processing stages of a published TOSCA template. +Domino Client issues an RPC call publish(tosca file). Domino Server passes the received tosca +file to Label Extractor that outputs resource labels. Domain Mapper uses the extracted labels +and tosca file to find mappings from resources to domains as well as the resource dependencies. +Resource to domain mappings and resource dependencies are utilized to partition the +orchestration template into individual resource orchestration templates (one for each domain). +If a translation is required (e.g., TOSCA to HOT), individual resource orchestration templates +are first translated and then placed on a template distribution workflow based on resource +dependencies. Message Sender block in the server takes one distribution task at a time from the +workflow generator and pushes the orchestration template to the corresponding Domino Client. + +.. _fig-pipe: + +.. figure:: ../etc/domino_server_processing.png + :width: 300px + :align: center + :height: 300px + :alt: alternate text + :figclass: align-center + + Domino Service Processing Pipeline + Typical Message Flow -------------------- -Internal Pipeline ------------------ |
