The document discusses Red Hat Enterprise Linux and its growing adoption rates. It notes that 84% of organizations plan to continue or increase their use of Linux in the coming year. Many organizations are migrating applications and workloads from UNIX and Windows to Linux due to benefits like lower costs, increased flexibility and hardware choices, and community driven innovation. Red Hat Enterprise Linux provides stability and a platform for mission critical, big data, virtualization and cloud computing workloads.

Increase choice of hardware,
Legal, corporate compliance
software, peripherals
Hardware refresh Lower TCO, increase ROI
Need to quickly adapt to
change Cloud readiness
