I am setting up an Exchange 2016 server.
We are hosting the servers at a server company and can only afford 3 servers.
I would prefer 4 servers (2 AD server, 2 Exch Server).
Given a three server scenario, which of the 4 servers above would be 'safer' to not have? A second Exchange server to run a DAG or a second AD server?
Virtualization isn't an option.
We have about 500 users.
We are migrating from Exchange 2010. In this scenario, we have two server and each is running Exchange and AD -- a possible, but not ideal situation.
I'm not looking for creative ways to 'get' another server. I'm trying to figure out what is the lesser risk, getting rid of a second Exchange server OR getting rid of a second AD server?
