Notes
There are a few good ways of architecting an IT setup for a Home, School or a Small Business. Showcased here is a capital and operational cost effective approach by using minimal/required networking hardware and a server with multiple virtualized applications. This solution template can be easily scaled out and adapted for enterprise organizations.
