A leading retailer was incurring high costs to run their mainframe portfolio for business applications. The existing system required 2800 million instructions per second (MIPS), over 10 million lines of code (MLOC), more than 3000 programs, and 1 TB of data. The client wanted to optimize their system for speed and agility to meet future business needs.
Infosys moved the mainframe applications and data to the Lintel platform, helping the client achieve annual cost savings of around USD 12 million.
After assessing the client’s existing mainframe setup, we took the following steps to address their issues:
With our migration approach, we were successfully able to:
After a thorough assessment of the client’s existing set-up and identification of key issues, the Infosys team devised a robust solution that included:
The solution enabled the client to:
Infosys identified the high-CPU-usage jobs and optimized them by:
Infosys also implemented recommendations in the test region and verified the MIPS savings.
The solution enabled a recommendations system and implemented key changes accounting for a total reduction of 371 MIPS, thus optimizing the client’s mainframe and boosting its efficiency.
After analyzing the client’s mainframe systems and the associated performance and cost issues, the team designed a solution based on the Infosys mainframe modernization approach. This involved:
The benefits of the solution included:
