Legacy business application systems running on mainframes are core to the business eco-system even
today for most organizations. However, at the same time, the operational cost of mainframe management and legacy application management is around 30 to 40% of overall IT budget cost. The trend indicates that the “run-the-business” cost keeps growing at the rate of 5 to 10% per annum, while the CIOs are grappling with the mandate on containing the mainframe operational cost and plough the savings benefits for investing into strategic initiatives.
The basic measurement unit for mainframe computing power is Million Instructions per Second
(MIPS). This unit, is used by both IBM and Independent Software Vendors as the pricing criteria for
software license and maintenance. IT organizations that maintain mainframe are required to
reduce the operational cost by reducing mainframe MIPS consumption of legacy applications.
MIPS optimization assumes new significance not only due to tight economic conditions, but also
due to proliferation of batch jobs, multiple test environments and sub-systems / shared resources.
In this white paper, we talk in detail about the typical lifecycle phases in a MIPS optimization program and the recommended approach to be followed, the risks / challenges involved and the corresponding mitigation measures.
