I have four physical hosts. each physical host is on a workgroup. each physical host holds several VMs. All of these VMs are on the same domain.
I am trying to set up replication, say from vmhost1 to vmhost3, and from vmhost3 to vmhost1.
As I understand it, I can only do this via certificate based authentication since the hosts are not on the domain.
The question is, where do I get the cert? Do I spin up a CA on the domain and issue it and then install it on all of the four servers or do I buy a public cert?
I'm confused about where I get my cert from.
