hehe speaking from experience, naming such a solution is much harder than setting it up and implementing it!
keep it IT and keep it tech.
think of the customers who are looking for the solution and imagine what they would be typing in google to search for it.
small business server
server small business
first server
first email server
do i need a server for my business?
i need a server for my business?
etc
etc
giving names to tihngs for the sake of it i think is kind of a waste.
its like selling laptops but calling them portable computation electrical devices. theyre both the same thing, but why complicate it but using a name people dont understand?
maybe market it as just server
but have Server A as "My First Server" and Server B "All in One Serer in a Box"
or something like that. its late and my creativity clocked off a while ago.
but you get my drift
