Hi Ravi,
We dont really have any diagrams that show the architecture and data flow. The data flow and architecture for conventional configurations has not changed at all in 17 from previous versions. Is there something specific that you are looking for with regards to architecture/data flow? I can answer a specific question if you are looking for something specific.
As a side note - we strongly recommend using Advanced Availability configurations for scaled environments for R17.0, as Advanced Availability offers better performance, and scalability.
For additional info about conventional configuration, see this section of the documentation:

Thanks,
Jon I.
