Re: Application design & architecture -- MIDRANGE-L

Rob,

There was nothing personal in my email.

You are offering an approach to design an architecture that would be the'best'. My point is that it has been done with SOA. The vendors are makingit complex, but in the big picture, it is rather straightforward. As abusiness-man, you would be one of the ~best~ people to understand it.


I encourage you to spend more time learning about SOA.

I tried to send a fairly neutral response to your previous email in
order to try and avoid a repeat of the green vs gui debate.

In that, you were determined to have a fixed viewpoint.  Is history
repeating itself?

Rob,

Why would we bother?

You don't have to. I didn't start this thread but responded to G4

We cannot get a green vs. gui debate "right".

SOA is Architecture that is the best practices of the approaches we have

tried to date. It is being worked on by brilliant minds and thoughtleaders

who have a much better view of business than is reflected inside these
programmer walls.

I have the advantage of not being trained as programmer and, having been
finance director, and then CEO, of 45 companies spread all over the
world and in many types of business, I like to think that I am able to
switch off my programming mode from time to time.

I am sorry that you think that  there are no brilliant minds in these
forums.  My impression was that at least some were quite bright and that
some were thought leaders in the iSeries community.  Am I wrong? Or have
you just insulted them?  How many of them have you met?

Maybe you are aware simply of the acronym? Maybe you heard if from one of
the bandwagon riders? If you have ever heard it called SOwA, then you are
probably also unaware of the truth of SOA.

SOA may be brilliant but to me it seems to have unnecessary complexity
although I freely admit that I haven't studied it in detail.  It may be
the best way but we will only know that by trying to discuss the various
existing and possibly new methods with an open mind.  If everyone knew
all the answers, then this thread would not have started.

I suggest we review how SOA fits the System i world - a far moreproductive
debate than attempting to reinvent the wheel, the automobile, the house,
public transport, kitchen appliances, and IT architecture.

The orignal wheel didn't have bearings or tyres.  These were later
improvements.  Not all methods of transport today use wheels.  Are you
suggesting that SOA is the answer for all time?  If so, then go and
start your own thread on SOA.  I wonder why you haven't done it before
if you are so sure of your ground.


Best wishes

Rob
