SUSE Linux Enterprise Server (
SLES) is a
Linux-based operating system developed by
SUSE. It is designed for
servers,
mainframes, and
workstations but can be installed on
desktop computers for testing as well. Major versions are released at an interval of 3–4 years, while minor versions (called "Service Packs") are released about every 18 months. SUSE Linux Enterprise products, including SUSE Linux Enterprise Server, receive more intense testing than the
openSUSE community product, with the intention that only mature, stable versions of the included components will make it through to the released enterprise product.
