Mainframe essentially keeps the world running." It may sound bold but it’s true. The quote above, which is from an IBM executive, Philip MacLochlainn, is indeed supported by stunning figures: “85% of all credit cards, 29 billion ATM transactions per year, 92 of the top 100 banks ... 12 billion passenger flights are booked” thanks to mainframe. And it makes no wonder to whom is familiar with mainframe’s history and the story of workload scheduling and management, which we contributed to write. If indeed the path of workload automation on the mainframe dates back to the 70s, it never stopped running towards the future, without leaving beyond the characteristics which made the mainframe the choice of thousands of customers worldwide: reliability, stability and high performances.
