I agree, once again.

I just favor a 2-tier as opposed to a 3-tier.  Doesn't seem to be that much
of a difference, in a way.  (Only a 150% increase in tiers...;-)  But each
added tier, in my blue-sky estimate, quadruples problems and increases
admin/support costs "x" dollars.

My preference would be a 1-tier system, but I don't see OS/400 on the
desktop, anytime soon...


I would also agree that "there will be a higher rather than lower percentage
of 400's being used as pure server machines (as opposed to all-in-one
processors) as time goes on, and this, in my mind, is the best use of the
machine."   But I think this is a trend that has been going on, for a while,
as green-screen customers leave the platform, Domino and pure Webserver
customers join the ranks.  I don't know whether there are many, if any,
*new* green-screen accounts coming to OS/400 (but am doubtful).  One reason
I'd like to see some e3000 customers get converted to iSeries.


But as far as security, I'm just not sure the 400 can maintain a level of
security and, at the same time, provide unattended access to secured data.

| And that's my point.  In fact, that's always been the point.  Let
| a machine
| do whatever it is the machine is best at.  The 400 is best at database
| processing.  The workstation is best at UI.  Let them each do
| what they are
| best at.  Separate the layers of your application so that each can be
| deployed where the best fit is.  This is why I think interconnectivity is
| the key to future application design.
|
| You know, both the AS/400 and the workstation are already n-tier machines.
| The AS/400 has a multitude of subprocessors (which is the reason it runs
| rings around other servers).  But even your workstation uses a distributed
| architecture.  Your graphics card has an onboard chip is basically another
| CPU.  Your network card has a processor, so does your SCSI interface.
|
| The idea of using each machine to its best potential is hardly
| new, and the
| trend is increasing.  I may be totally offbase here, but I am willing to
| wager that there will be a higher rather than lower percentage of 400's
| being used as pure server machines (as opposed to all-in-one
| processors) as
| time goes on, and this, in my mind, is the best use of the machine.
