Guide on how to do large scale deployment

Currently, the documentation is sparse on the following:

* How do you dedicate a server to be one specific GRR component like the AdminUI, Frontend, or Worker?
* How does clustering work?
* What happens in a partition?
* How do multiple Workers or Frontends discover each other?
* What ports are used?
* Example configurations

Would it be possible to elaborate or have a guide addressing this?

Start by mapping the deployment roles named in the issue: AdminUI, Frontend, and Worker. Research clustering, partition behavior, component discovery, ports, and example configurations, then organize the findings into a large-scale deployment guide. Done means the documentation answers each listed question with usable configuration examples.
