Can there be roles on different physical servers?

Question

Computer networks

For example, on one server the dns role is installed, and on the other - dhcp.
There are 50 computers and you need to create a local network with a dedicated server. There are also 10 separate computers with their own network. The obscure has been removed. Probably meant: each subnet has its own server.

Answer 1

Yes, you can, and this is a fairly typical case. We have separate servers and dns and kerberos and a couple of dhcp, though in separate virtual machines, and everything else in different ways.

Answer 2

It is possible and real. And it will work.
But for such a small network, from my point of view, it makes no sense. Unless, as indicated above, virtual machines. But the output point is still the same - this is the physical server where they are deployed.
Spreading makes sense if you start using a caching DNS and a caching proxy server. And they are under a lot of pressure.
And so for a network of up to 1k people on linux, Pentium 4 is also suitable)

Answer 3

The best practitioner recommends just spreading vital roles to different servers and also making clusters. Only primary DNS cannot be migrated from a domain controller. And DHTsP can (and should) be deployed separately.
