It's too costly and it's difficult to replicate the work environment at home for practice. Review collected by and hosted on G2.com.

"IBM Z review"
4/5
What do you like best about IBM Z?

I have been using IBM Z processors for the last 10 years and the main pros are its MIPS processing time and how secure the mainframe system is. This is the reason why the legacy systems are still in place. Review collected by and hosted on G2.com.

What do you dislike about IBM Z?

There is nothing to dislike but the only reason people are moving to new platforms is because of the cost. Review collected by and hosted on G2.com.
