Mainframes are expensive? That depends on what you’re looking at.

In this three-part series on SHARE’s “President’s Corner” blog, Rocket’s Janet Sun explores and dispels numerous myths around the mainframe.

Mainframes are expensive? That depends on what you’re looking at.Here’s an excerpt from Part 1 of “Don’t Believe the Myth-information about the Mainframe:”

“Most companies don’t use mainframes” they said – Seriously?  SHARE, the mainframe community, represents more than 20,000 individuals from nearly 2,000 companies.  Those companies include: state and federal government agencies, universities, retail, energy, manufacturing, banks, and insurance companies.  More specifically:

  • 96 of the world’s top 100 banks, 23 of the 25 top US retailers, and 9 out of 10 of the world’s largest insurance companies run System z
  • Seventy-one percent of global Fortune 500 companies are System z clients
  • Nine out of the top 10 global life and health insurance providers process their high-volume transactions on a System z mainframe
  • Mainframes process roughly 30 billion business transactions per day, including most major credit card transactions and stock trades, money transfers, manufacturing processes, and ERP systems.

That doesn’t exactly sound like a technology that’s no longer in use, or even going away anytime soon.  So, what are the other most common myths about the mainframe?

  1. Mainframes are old
  2. Mainframes don’t run modern applications
  3. Mainframes are expensive
  4. The skills to manage mainframes are not available or you need more people
