More Reliable than Microsoft

In the same vendor value survey, those same senior managers also rate Red Hat as a company that is one of the most reliable software vendors. We deliver high quality products, meet our commitments, and are responsive to our customers' needs. Red Hat consistently delivers a superior experience.
Companies that build their business on technology rely on Red Hat Enterprise Linux. NYSE Euronext, DreamWorks Animation, Salesforce.com, and other diverse companies around the world trust Red Hat Enterprise Linux to minimize downtime, provide sound security, run their largest workloads, and drive their businesses with assurance.
More open. Run the applications your business needs on the platforms you choose.
Today's IT infrastructures are multi-vendor and multi-platform. When you select software for your datacenter, you must consider how well it will operate in that heterogeneous environment. Created with a truly open process, Red Hat Enterprise Linux is an open platform that gives you flexibility, choice, and access to a broad range of innovations to help you control your costs and your future.

More Open than Oracle

A subscription to Red Hat Enterprise Linux provides access to any currently-supported version that covers your deployment, whether directly on a server, as a virtualization host, as a guest on the major hypervisors, or in clouds. You can upgrade, migrate, or re-architect without having to renegotiate your agreement. Moreover, the open source licenses that are delivered through our subscription model give you the right to adapt the system to your needs, on your schedule.
Red Hat collaborates closely with leading independent software vendors (ISVs) and independent hardware vendors (IHVs) to produce an open enterprise operating system that runs well for all users. Red Hat Enterprise Linux is designed to deliver the latest hardware innovations from many vendors, and is optimized to provide a high-performance and stable platform for a broad portfolio of enterprise and leading-edge applications, including SAP, IBM Lotus Domino, Oracle, SAS, and IBM WebSphere, database, and middleware software.
And all this is supported by Red Hat's global support and engineering teams that work alongside our partners every day.
More comprehensive. Standardize on the platform that covers it all.
Virtualization is a native feature of Red Hat Enterprise Linux 6, allowing your applications to have a consistent environment across physical, virtual, and cloud environments. All the work that you do to set up your applications – configuration, creating security policies, defining policy-driven resource allocation, ensuring regulatory compliance, and optimizing performance through system tuning and application diagnostics – is transportable across all of your deployments. And because Red Hat Enterprise Linux itself is independent of and portable across networks, hardware, and hypervisors – including Hyper-V and VMware - your operations are consistent and efficient wherever you choose to run them.

More Comprehensive than VMware

Red Hat Enterprise Linux provides support for your new and existing applications, the latest middleware products, modern cloud software architectures, and new runtime frameworks. But Red Hat provides much more than just a universal interface for applications. Red Hat Enterprise Linux offers a pervasive foundational environment for developing datacenter policies, procedures, and services. From identity management and governance, to a responsive, flexible, and complete Web applications stack, to effective management of scores of servers and massive storage, Red Hat Enterprise Linux should be a critical part of your datacenter infrastructure.
