Don’t be shy; ask an expert!
It is very difficult to say that a specific architecture design is “ideal” because, as with many things in engineering, everything here is a matter of compromise. You will never “get it absolutely right,” and some of the questions you will meet will likely be so hard that sometimes even PhDs and university professors would end up on different sides of the discussion. Be humble and ask for help if needed; don’t rely solely on yourself and the few people you are working with. If there is a friendly data scientist with a penchant for stats and thorny statistics in your company, sometimes they will be the only soul who can help you. The same holds for cybersecurity, or some exotic expert domain subject that your system deals with.
An external expert can bring a different view to your own and your team, and asking for expert help will decrease the risk of what you are trying to achieve, always.
If you are not so...
