Bahmni Server Deployment Architecture
Technical Document
This document details out what all components and applications are deployed in Bahmni Production Server at a high level. For failover / disaster recovery, some deployments may use a Primary/Secondary or a Master/Slave deployment architecture.

Comments
Thanks @Vinay Venu. Exactly the kind of inputs I wanted. Is it possible for you to help by drawing a paper (whiteboard) representation for me, I can then transform it into Confluence Diagram? I also think the diagram can be further simplified, and maybe have have different diagrams for different concerns (like you suggested a separate data flow diagram).
1. The lines represent data flow, which is irrelevant for a deployment architecture. It is also incomplete since data also flows into apache, and ultimately to the user. Let's have data flow in a separate diagram.
2. If we are showing 3rd party software (mysql pgsql etc), we should also show oviyam
3. Do the colours mean anything? If not, we should remove them. It is a distraction
4. Saying that bahmni-reports contains jasper server is misleading. It uses dynamic reports, which uses jasper library
5. bahmni-lab-connect is served by the tomcat that is sitting inside openmrs rpm. Not sure how we would represent it.
6. The fact that rpms embed tomcat is not consistently shown across all rpms (erp-connect and bahmni-reports need to be fixed)
7. Maybe worth trying to layer components one below the other?
