Where can I find ready-made samples of the drawn application architecture?

Question

Software design

Let's say everyone did a blog, or a shop. So, in order not to upload every time, not to pick the code, I wonder if there are resources where they post their past architectural solutions . How did they implement relationships between models, etc.?
Preferably all drawings, but to see the big picture at once.

But this is too general. The level is too high, and you have to sit and think about how to organize connections, who is where with whom and why.

Answer 1

Let's just say there are design patterns. Typical models, etc. You will find this in articles on application architecture or with exact Google queries, for example, "acl system uml diagram"
There are also resources where people using design software post their work.
