I am setting up a dedicated server that will be running Windows Server 2012, and hosting about 5 Linux VMs, and 1 Windows VM. All the VMs are independent and do not interact with each other. The server is being used to host several websites and apps on each VM.
A few questions:
I can setup the WS 2012 as a domain or as a workgroup. What is better for this purpose, and what are the advantages/disadvantages? Any reason why I should pick domain? The server will be hosted at a datacenter so I'm afraid a workgroup may not be as secure?
If I go with domain, I suppose I could also setup AD and DNS on the same server. I see the benefit of DNS, but do not think AD is necessary for my purpose. Can I create a domain without having Active Directory?
Instead of running DNS on the host, I could use the name servers from my registrar (Godaddy). Is this better or should I create and use my own DNS?
I want my hosting server to be reachable by an externally resolvable name such as myserver.com. The other VM's, I would like to have reachable by something like vm1.myserver.com vm2.myserver.com, etc. What's the best way to set this up? a. Can I just make my FQDN for my main server myserver.com instead of like mainhost.myserver.com? Any drawback to this since the externally resolvable site IS the FQDN of the main server?
