5. So far
 Mainframes is a very stable
environment
 It has been there in the Software
Industry for more than 40 years
 No new technology can totally
replace Mainframes because of its
architecture and efficiency

6. Current trend
 Around 80% of Mainframes projects
are maintenance projects
 Only 20% or less are development
projects
 The reason being the cost factor. The
hardware maintenance cost and the
initial investment required is too
high.

7. Current trend
 Migration projects are the current
trend in the market
 Reasons:
User friendly screens
Maintenance cost

8. Future
 A survey to determine the current
demand for mainframes found that
more than half of the respondents
still have major applications running
on mainframes
