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.
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?
- Mainframes are old
- Mainframes don’t run modern applications
- Mainframes are expensive
- The skills to manage mainframes are not available or you need more people
