UNIX to Red Hat Enterprise Linux: Now is the time

Last Updated:

Today’s IT organizations are still managing in-house infrastructure and applications while also being asked to integrate cloud and mobile environments — without additional resources. Many enterprises cannot meet the challenges ahead with inflexible legacy UNIX systems. IT teams need the cost savings, security, flexibility, and compatibility that Linux® can offer.

The viability of the UNIX platform is declining, with many IT vendors winding down their investments in UNIX systems and shifting focus toward Linux platforms. In addition, new technologies and applications are often not certified or tested for UNIX systems. For example, 82% of applications running in Amazon Web Services (AWS) are running on Linux, according to InfoWorld.1 Inside public cloud infrastructures, applications are built to run natively on Linux systems. Linux, not UNIX, is powering current technology innovation.

If you are still running UNIX, it is past time to switch. Red Hat® Enterprise Linux, the world’s leading enterprise Linux platform, provides the foundational layer and operational consistency for traditional and cloud-native applications across hybrid deployments.



A study by Alinean2 compared Red Hat Enterprise Linux on x86 servers to UNIX running on proprietary RISC-based servers. It showed the Red Hat solution has a 79% lower total cost of ownership. These savings are derived in large part from the higher performance that Red Hat Enterprise Linux delivers on the x86 platform. Also, Red Hat Enterprise Linux runs with less administrator oversight, providing the ability to manage 64% more servers compared with UNIX. This ease of administration reduces operational costs and boosts staff efficiency. By migrating from proprietary technology to Red Hat’s enterprise open source software running on industry-standard Intel servers, Intermountain Healthcare has drastically reduced its IT costs  —  including licensing and staffing costs.

“Our Intel and Red Hat solution has helped us reduce costs while still getting the availability, power, and performance that’s required in a clinical environment,” said Bret Lawson, director of infrastructure and operations of Intermountain Healthcare.


Red Hat Enterprise Linux was developed in cooperation with security-conscious partners  —  including financial institutions and defense contractors  —  with safeguards built in to maintain 99.999% uptime, combat intrusions, and reliably run mission-critical applications. It is hardened, certified, and backed by the industry-leading Red Hat Product Security, Support, and Engineering teams and the global open source community. Red Hat Enterprise Linux gives you security and auditing technologies  —  and rock-solid predictability — to ensure the right applications, processes, and services have access to only the necessary resources. 


The average organization spends 70% of its IT budget and untold amounts of staff time maintaining existing applications. Red Hat Enterprise Linux lets you take control of your day, spending less time reacting and more time delivering business value and cost efficiencies with fine-grained management controls as well as scaled-out automation across your datacenter. 


IT teams know they must deliver innovative products and solutions to keep their companies competitive while still controlling costs. That’s why more than 90% of Fortune 500 companies rely on Red Hat products and services.3Raiffeisenbank, a banking institution that provides a wide range of services to private and corporate clients in the Czech Republic, needed to replace the aging hardware and IBM AIX UNIX operating system that supported its data warehouse. By migrating to Red Hat Enterprise Linux, the bank has tripled system performance and maintained stability while cutting total cost of ownership. “One year after the migration, we are seeing the cost reductions we predicted,” said Jiří Koutník, head of system administration at Raiffeisenbank. “Over five years, we will reach our target of reducing TCO by half while also increasing performance.”
