Redhat Linux Enterprise AS

Red Hat Enterprise Linux AS (formerly known as Red Hat Linux Advanced Server) is a powerful enterprise solution that supports the largest X86 compatible servers. Red Hat Enterprise Linux AS is an excellent solution for large server deployments.

Why is RHEL an improvement? The original idea behind Linux was a version of Unix for the workstation. It is so robust that it is very good at server applications in spite of that not necessarily being it's main intent. High-end server applications are the intent of RHEL, so all the quality, reliability and stability that went into Red Hat originally have been put into RHEL and its server capabilities.

RHEL products have a release cycle of twelve to eighteen months, longer then that for Red Hat, which adds stability. They are also provided with subscription services, with errata and patching service to make your system reliable and secure.
