When you booked your airline ticket to fly into this Pacific NW Software Quality Conference, did you think of the computer that made your reservation?
When you paid at WALMART recently – where was that computer that processed your payment transaction, from the POS Terminal, through your credit card company, all the way to WALMART?
Last time when you paid your credit card bill, did you know about the computer that processed your online banking payment?
It is the same computer system, for all of those transactions.
Did you think about the thousands of other travelers, shoppers, bank customers who did similar transactions as you, at the same time? Did you think about the capacity, speed, and security of that computer?
It is the same, big, powerful and the most securable computer system, for all of those transactions.
It is The IBM Z mainframe. Z = Zero downtime for 24 hours, 7 days a week, 365 days a year, for mission-critical applications.
How is the hardware and software for that system developed?
How is it tested? Join me on the historic journey of a computer system, a platform announced on April 8, 1964. The story of a system that runs on principles.
Key takeaways include:
- IBM mainframe history overview 1964-2019
- The Mythical Man-Month & the largest hardware and software project in IT history
- Key design principles: backward compatibility, the effectiveness of the User Interface
- Key operational principles: 24×7 availability, security, scalability
