I want to build a reliable network, which option is better?

Question

linux

at the moment, win 2008 is installed on one server, it is also a domain controller and has a shared folder on it, a couple more virtual machines in hyper-v. Is there a way to distribute it all separately, for reliable operation.

Answer 1

Is there a way to distribute it all separately, for reliable operation.

And add points of failure? You can’t think of anything other than how to take out virtual machines. Will they be of any use if the server is unavailable is a separate issue.

Answer 2

Is there an option to somehow distribute this all separately, for reliable operation

Of course, this is how fault tolerance increases. Only not by the banal separation of different services on different pieces of hardware / virtual machines, but with concomitant redundancy - a duplicate AD controller, storage servers, DNS, etc.
You need to understand that when you start increasing reliability, you need to increase it everywhere - both on the network infrastructure and on storage systems, power grids ... otherwise, in the event of a failure of one of the subsystems, everything can fall apart despite the redundancy in other places.
