A centralized network architecture means that there is a structured (logical) hierarchy for system configuration and management.

If one location were to fail, one could easily have backup systems already in place to failover to.

Like they say,"don't put all your eggs in one basket." Let's take the situation of 9/11's tragedy where some firms went bankrupt. They were not able to recover after the 9/11's Thu, 28 May 2009 05:22:54 GMT webadmin@itbusinessedge.com http://www.itbusinessedge.com/cm/message/1422?tstart=0#1422 2009-05-28T05:22:54Z 5 months, 3 weeks ago http://www.itbusinessedge.com/cm/message/1421?tstart=0#1421 It is obvious that if you were to recover an organization from a disaster it is best to use a centralized model. This is true if only all the necessary backup data is available. The recovery process is easier and faster.

I have seen several poinient reasons to use a Cetralized approach. I can agree if we bring into the thought process items like databases and specific applications. These really should drive the schema of your Wed, 27 May 2009 14:46:12 GMT webadmin@itbusinessedge.com http://www.itbusinessedge.com/cm/message/1411?tstart=0#1411 2009-05-27T14:46:12Z 5 months, 4 weeks ago http://www.itbusinessedge.com/cm/message/1410?tstart=0#1410 Warrick makes some valid points. If you use a decentralized model it will be less cost effective for your company. It will take more time to try and figure out whatbsystems and aplications need to be brought back online after a disaster.

As long as you are doing backups regularly; a centralized model offers control, efficiency, and economy. Its centralized control decreases technical risk. A decentralized model can waste time and cause cost to increase.

Reasons for choosing the centralized model are:   1. Allows for streamlined command and control of personnel coordination.
