Centralising and Decentralising
We often must decide for or against central or distributed approaches.
The following facts can aid our decision:
-  Reasons to move towards a direction 
-  Problem we want to solve 
-  Try to centrally manage as many elements as realistically possible 
-  Increasing centralisation increases the need for handling special cases 
-  Once a technology becomes widely adopted it also becomes a target for
centralised management 
-  A move towards centralised management is like any other change or upgrade, but 
-  ... it offers us a unique chance to make a good impression 
-  Listen to customer concerns, but remember that IT should have the last word 
Centralised management candidates:
-  Distributed systems 
-  Consolidate services on less machines 
-  System administration 
-  Infrastructure decisions 
-  Procurement 
-  Support
