The technological components will work with each other. ArcMap works ok
under Citrix, and I would presume Manifold would too. A T1 should be
sufficient, however, that's only point to point, once you get inside your
LAN, pass firewalls, routers, switches, etc. you may find that the latency
degrades performance to the point where your people will start questioning
your strategy, if not more. DO NOT go to ArcMap 9.0, not now, not for a
while, and certainly set up a test-bed area before going live with this
"ASP" setup. The real problem is the total cost of ownership is not a
compelling strategy. NONE of the GIS software vendors, and for that matter,
NONE of the database companies really make deploying an architecture that
you are planning economically feasible. ESRI strategy is ArcIMS, however,
that's very pricey, and they may view your system as a "commercial" ASP and
thus take both arms, both legs, first born, etc. in licensing fees and
support WITH NO upside in performance for your people. Have you considered
how you will handle imagery or 3D models ? Bandwidth consumption on those is
exponential. Will you host the server farm yourself ? Physical and network
security ? I suggest asking Citrix to send someone out to demo with your
applications, or provide you case studies, real metrics on performance.
They have reference clients in our industry and should be able, if not
willing, to provide solid evidence of previous deployments. Remember, your
SLA with your T1 provider will NOT cover ArcMap crashing, Windows crashing,
Oracle crashing, your hardware crashing, etc. etc. so don't fall into a
sense of invincibility if your T1 provider says they can provide 5 9's
[99.999% uptime], it's effectively a meaningless metric, because 5 9's is
almost a commodity at this point.
Don't know what your annual bill is to ESRI, or others, but suggest you try
and leverage them into a TRUE "utility computing" pricing structure. That
is, you use it [pick your metric here, per minute, per hour, per month] and
you pay for it. You can clearly see why ESRI and others DO NOT embrace this
model, as it would quickly become very popular, and like the wireless plans
that offer 3,000 anytime minutes for $40/month, the GIS software vendors
would quickly find themselves working hard to be competitive and would
actually foster real innovation and more user-friendly packaged deals.
