Good afternoon, help with advice on how to properly distribute power and what licenses to take.
Servers should have: 1 server. gateway server and backup domain controller AD02. Server 2: Hyper-V, AD, SQL, 1C8.3(25 users), WSUS, Kaspersky, DFS01.
Users 50 people. How best to distribute and purchase. If possible, write what you can save on without buying a license and it will work.

Answer 1

When using virtual servers, Microsoft comes with 1 license for 2 servers.
The most expensive thing in all this is SQL licensing, unless you use Linux and Postgres for 1s.
You won't save much on the rest.
In terms of capacity:
memory is consumed by SQL, WSUS.
percent guzzle Casper, 1C
disk guzzle 1C, SQL
I don’t see high-speed disks with you, therefore you will sag very heavily on the disk with a significant load from 1s. Processors of only the first server are suitable for 1s. it uses only one core at all times and frequency is critical.
It all adds up like this:
1) AD1, 1C, Casper
2) AD2, SQL, WSUS

Answer 2

Can I ask myself a question? the bottom line is that there is an idea to transfer the 1c server to linux, this is done quite simply, but what about the Windows clients? will they connect in the same way as to the 1c server on Windows?
