Is your feature request related to a problem? Please describe.
We have outlined some options for feature serving and model inference in this documentation: https://docs.feast.dev/v/master/getting-started/architecture/model-inference

In it, we briefly discuss communication patterns and their tradeoffs (elaborated further here: https://docs.feast.dev/v/master/getting-started/architecture/write-patterns).

We don't have an architecture diagram to support these pieces.

Describe the solution you'd like
For a Fintech article I'm writing, I ended up drafting this diagram. I think we could potentially adjust this to use in our documentation.

Describe alternatives you've considered
N/A

Additional context
Good diagrams provide clarity and what not, so I thought this would be useful.
