IBM® mainframes process two thirds of the world’s business information every day, and have been doing so for decades, because of the many strengths provided by the mainframe, such as high availability, good redundancy, high performance I/O capabilities, and much more.

This IBM Redguide™ publication describes the business drivers, their impact on IT, and how the System z® platform can be a major player for the business solution by providing flexibility, responsiveness to customers and market needs, as well as cost effectiveness. It also discusses the mainframe hardware, software, and environment, with an emphasis on the features and capabilities that make the System z mainframe the system of choice for a business enterprise.
