Overall Satisfaction with IBM Z

Our company runs our credit card, debit card, and store card systems primarily on IBM Z. We do all thing credit, debit and store card for our clients. It is about 60% of revenue.
  • Transaction processing. Nothing better than DB2 and Information Management System (IMS).
  • The best security in the business world.
  • Best place to store data for retrieval.
  • More GUI interfaces into z/OS.
  • We could not have grown to be the world's largest card processor without it.
Pervasive encryption will be the salvation of our business as security becomes more and more of a primary business requirement.
We have not exploited this. It is becoming a major issue in attracting new talent.
We believe in the right workload on the right platform. Z/OS is able to run more workloads than ever before and still with the lowest headcount required.
It can run Linux, UNIX, DB2, MQ and more from under z/VM.
