Everything RHEL: News, guidance and support

Red Hat Enterprise Linux has made some strides in real-time computing, reliability and even security. This guide provides news, tips and product comparisons to help you assess RHEL versus distributions like Novell's SUSE Linux.





I. RHEL for real-time and mission-critical computing
Over the past year, Red Hat Enterprise Linux (RHEL) has made serious strides in real-time computing. Now, with new offerings like Red Hat MRG, which offers 100-fold increases in computing speed while also providing greater reliability and system stability, RHEL is poised to become the standard-bearer in terms of real-time performance computing. This section explores RHEL's advances in real-time computing.
