The Mainframe has been around a long time, and as such it is an easy…

How Much does Security and Up-Time mean to your Business?
All computer systems experience unplanned outages. The mainframe does. Cloud services providers do.
Some of these outages are self-inflicted from code changes implemented into production with insufficient testing. Others from unsupported versions of systems software or new systems software where edge cases weren’t considered.
Often, problem determination and resolution can be faster on the mainframe since the systems discipline and centralized control are often more mature.
The ability to get systems back up and running after an outage is critically important to a firm’s market and brand reputation.
But even more important is the need for systems not to go down in the first place.
The mainframe is the most secure high volume computing platform available.
Most banks, insurance, capital markets, healthcare, government, and other companies with high availability needs all still use the mainframe for their critical compute. And will for a long time.
Application development and regression testing is also very mature on the mainframe. Test coverage, dead ends, zombie code, and edge cases are often easier to identify and consider on a centralized mainframe system than across the Internet connecting thousands of distributed servers and storage systems.
The question to ask then is: Why would I give up all the above?
Instead, why not focus on optimizing the cost of the Mainframe platform?
In our experience most organizations can optimize their MF run costs by up to 30%
