I am involved in supporting certain middleware applications of banks on tandem. The version I am
involved in is getting replaced with a new CORBA/COM enabled one. Will the existing clients go for
an upgradation? Or if they chose to stay back, what potential changes can we expect in business
logic implementation of transaction handlers?

users will go for an upgrade or not based on their experience with you and their systems as
well as their other commitments (in terms of time and money). I'm very big on CORBA and believe
that over time it will save enormously on maintenance/upgrade costs. Its architecture builds in
security and sharing right from the beginning in a way that some other architectures do not. One
approach is to make a chart of all products you are considering and the architectures they support.
If you can show your users that 90% (or more) of them use CORBA, then the CORBA choice becomes less
important than the choice of a specific application server. If the move to CORBA is going to happen
eventually (such a chart would indicate that to be the case), it's just a matter of timing.This was first published in July 2001
