Title: RE: Mid-Tier architecture question

** Hi James   Scenario 1 – MT Servers local to ARS, they would be on same LAN as the ARS server and firewall(s) would be between the end-users browsers and this. ARS---FW---MT --------------pipe--------------- FW------Users   Scenario 2 – MT Servers local to Users. ARS----FW ---------------pipe---------------- MT---FW---Users   The pipe would probably be about 2Mb and is clearly the bottleneck.  So is it quicker to send the MT to ARS traffic over the pipe (scenario 2), or the browser to MT traffic (scenario 1)   Regards   David Sanders Remedy Solution Architect Enterprise Service Suite @ Work ========================== ARS List Award Winner 2005 Best 3rd party Remedy Application   tel +44 1494 468980 mobile +44 7710 377761 email [EMAIL PROTECTED]   web http://www.westoverconsulting.co.uk   From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of McKenzie, James J C-E LCMC HQISEC/L3 Sent: Tuesday, August 01, 2006 8:51 PM To: arslist@ARSLIST.ORG Subject: Re: Mid-Tier architecture question   Dsvid: Where would the MT servers be located?  What is the size of the pipe between the ARS servers and the remoted MT servers?  Also, is there a firewall/network appliance that would be placed between your ARS server and the MT servers?

Imagine a central Remedy application and database server(s) based in the US, with users based in the US, Europe, Asia etc.  Most user access is to be through the Mid-Tier. Say we decide to have 3 Mid-Tier servers, the questions is, are we better to locate the MT servers locally to the ARS platform, and transmit the Mid-Tier to client browser traffic over the WAN, or is it better to locate the MT servers locally to the users, and transmit the Mid-Tier to ARS traffic over the WAN. My **guess** is that having the Mid-Tier servers local to the ARS server would give better performance as I expect the most intensive traffic to be between the MT servers and ARS, but I have no evidence for this from a real-life situation.  Has anyone compared these types of architecture and discovered performance differences? Thanks for any information.
