Hi Joshua, In a very broad sense you're right. The details are like this:
- each machine that is part of a node has a Service Manager (this starts and stops individual services, e.g. VideoService) - each node (group of one or more machines) has a Node Service, this provides a single point of communication for the entire node. - The venue client is the user software, and when run with --personalNode, it starts a Node Service and Service Manager locally. Is that enough detail or are you looking for more? --Ivan > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Joshua M.
