CTP has remarked that virtual server technology has become common place both on-premises and for cloud hosted services, as the technology allows better utilization of hardware resources, taking advantage of the tremendous advances in computational capacity that has come about even for entry level production equipment.

But – can a small business elect to just put in a single on-premises server, with no virtual server technology?

Of course!

That single server can be configured as a domain controller, provide file shares and host anti-virus services and other services that might be required for the business. There are some security reasons why it would be best to move e-mail service to a hosted service such as Microsoft Office 365 – in fact, this arrangement is in common practice for small businesses.
