Modernizing mainframe applications: Why and how

Learn how a mainframe application modernization strategy lowers costs and adds flexibility that can put your organization at a competitive advantage.

A mainframe modernization project can pay off with cost savings and greater flexibility and adaptability to quickly changing demands. While changing a business-critical mainframe application was once considered too risky, mainframe environments today can be updated with minimal impact with a well-planned modernization strategy.

In this three-part series, Infostructure Associates president Wayne Kernochan outlines the basics of a mainframe modernization strategy, the costs of leaving a legacy application as-is versus updating, and how Web services, virtualization, and cloud computing fit into a modern mainframe infrastructure.

The second part of the series takes an in-depth look at the price businesses pay by failing to modernize their mainframe applications as well as key considerations and risks for IT to keep in mind when undertaking a modernization project.

Web services and cloud on the modern mainframe: Part 3
In the final installment, Kernochan talks about how Web services, virtualization and putting mainframe apps in the cloud can lead to significant business benefits and technical advantages.
