  • Thread-topic: Server Question
Greetings Gino,
I agree with you that this is a lot of info.  I think what it boils down to
is that there are things that OSX Server does add value for, even in the
cloud and there are things that a bare bones linux will do just as well.

For a production level WO product that is being churned out with new
versions, a Linux driven virtual machine that can be deployed anywhere with
very little overhead makes a whole lot of sense.  In that case, you don't
need the bells or whistles, and the Linux VM can be whittled down in size.

For a test environment or development environment, the virtual OSX makes a
whole lot of sense.  In those cases, the bells and whistles come in handy.
Thus it is easier to argue for the value in that case.

The value I see in OSX Server is in the small business / lab environment
where we don't need the overhead of Microsoft's AD or Sun's big systems.
OSX Server is a much simpler solution and allows my lab to focus on other
tasks.  From time to time, I have to address the science of security and
other such issues so that I have the intellectual muscle to thoughtfully
address the bureaucracy and concerns of the lawmakers.  OSX Server's strong
design and useful utilities provides the luxury of time to do those kind of
things.  The fact that I can run WO and my scientific apps on it is an added
bonus.

That is just my opinion, and I do not speak for any one or thing other than
me.  I just report the facts honestly and fairly.

V/R,
