A Second Chance to View the Destination z Webinar

More than four months in the making, the first IBM Destination z webinar offered an expert look at current mainframe trends and the future of the platform. About 265 people attended the June 5 online event, which was more than half those who registered.

For those who couldn’t attend, the session is now available to download at the IBM Systems Magazine (cosponsors of the webinar) Event Archive!

The on-demand webinar features Bryan Foley, program director, IBM System z Strategy, and Innes Read, enterprise architect, TCO, IBM Software Group Strategy. Their presentation was based on comments and questions from the mainframe community, which were submitted in the Destination z Community Forum and via email. They discussed System z today, namely zEnterprise EC12, the strategy outlook for the mainframe, and the platform’s true TCO in light of other platforms.

In his opening statement, Foley likens the mainframe to a Corvette, which has a proud, successful history but whose latest model is a powerful modern machine. “We have continued to innovate this platform, so that while it continues to its legacy history, it is a modern platform to do business on,” Foley says.

This is seen in the growth in zEnterprise adoption among organizations in both emerging and established markets in recent years, Foley notes. He goes on to explain the value proposition of the System z platform in terms of IT priorities and trends, such as analytics, cloud, mobile computing and security.

In his part of the presentation, Read offers some real-world TCO examples, demonstrating that when measuring cost per unit of work, the mainframe has a clear advantage over competitors—particularly as workloads increase. Perceptions about high costs are easy to understand when comparing one mainframe to a single server, he admits, but frequently a single mainframe system does the work of a multitude of servers. So the true costs of moving off the mainframe to myriad servers can be staggering.

He also explains how chargeback accounting at some organizations sometimes falsely inflate the mainframe’s perceived cost, especially when unrelated, fixed costs get added to the mainframe cost bucket and billed back. “We’ve now come across three individual customers who recover the cost of their company jet through the mainframe,” Read adds. Unfortunately, chargeback drives incentives, so if organizations think the mainframe is expensive because of such accounting methods, it creates an incentive to move off.

These are only a few of the insights offered. So don’t miss your next chance to view the Ask the Experts webinar.
