Business challenges

  • Optimize availability of United’s critical internal- and passenger-facing applications to ensure a superior customer experience from first contact through return trip
  • Ensure business continuity as United integrated operations following its merger with Continental Airlines 
  • Boost IT team productivity to enable members to focus more time and resources on innovation that boosts competitive advantage and less time on routine maintenance
  • Improve security compliance and streamline audit execution
  • Minimize IT footprint through consolidation, including operating systems

With Oracle Linux, we found an operating system that lets us maximize the uptime of our applications. The ability to patch our kernel live with Ksplice, without a reboot, is a huge win. It also helps us meet security compliance patching requirements.
