Why Migrate to x86 and Linux

Hardware refresh

Running IBM, SAP, or SAS

Increase choice of hardware,software, peripherals

Need to quickly adapt to change

Migrate to commodity, butretain skills

EOL of database, operatingsystem, hardware maint.

Cloud readiness

Lower TCO, increase ROI

Legal, corporate compliance

Linux like tools, might as wellmigrate to Linux

Reduce TCO

● Access to all shipping versions

● Steady stream of enhancements

● Proactive security updates

● Additional hardware/software support

“Our analysis was correct as supporting the commodity hardware that Linux runs on is much more affordable than the support that we needed to maintain proprietary hardware. The savings in support, both internally and externally, associated with Red Hat Enterprise Linux is significant for us.” — Dean Abercrombie, Cox Enterprises UNIX and storage systems group manager
