Yeti Distributed Install

Can you share what yeti components can be installed on separate servers for distributed installation. I would appreciate if you can also provide minimum system requirements as well. The components I am considering are:
Routing DB
WEB Interface
Management Server
SEMS Nodes
Load Balancer
CLI Utility

From documentation provided I am able to infer that SEMS nodes can be installed separately. WEB and Routing DB needs to be on same host for optimal performance and CDR DB can be on separate host. What I need to know is that on what host(s) redis needs to be present on and Management Server should also be on web interface host or should be installed on separate host for scalability. And to which hosts should I install Load Balancer and CLI utility. Thank you.

Actually configuration depends on your needs. Redis and Management Server is used by SEMS so they can be installed separated.
