The SUSE Linux Enterprise is a multimodal operating system that is designed to handle business-critical workloads with an efficient and secure IT infrastructure. The latest release is designed to make it easier for openSUSE Linux community or development subscription users to upgrade their systems to the SUSE Linux Enterprise 15 with full functionality through the openSUSE Leap Linux distribution.
OpenSUSE Linux is an open source community project that is freely available for download and use. This version of the operating system is built atop the open source Linux kernel, and it consistently receives updates for its framework as well as the many tools and applications that the open source SUSE Linux community develops. OpenSUSE benefits all SUSE projects and releases by being the testing ground for many features that are later employed into commercial editions of the product. SUSE Linux Enterprise, for example, derives directly from openSUSE’s tested features. This operating system is a more stable and commercial server-oriented version of openSUSE that is often employed by businesses and corporations to manage their computer systems and data. SUSE Linux Enterprise products consist of the SUSE Linux Enterprise Server (SLES), SUSE Linux Enterprise Real Time (modified SLES), SUSE Linux Enterprise Desktop (desktop client), and SUSE Linux Enterprise Thin Client (SLETC). Taking advantage of the fact that SLE derives from the testing and development of features in openSUSE, the latest release of the operating system, the SUSE Linux Enterprise 15, allows openSUSE community users of the operating system to upgrade to the more stable and concrete version from within their own OS. This does not however entail a new free download; the privilege is up for grabs for existing openSUSE users only.
The SLE 15 sees the addition of the OpenJDK 10, the open source implementation of the Java SE 10. The unixODBC, SLE’s open database connectivity API, is discontinued and the psql0DBC driver of the object-relational database management system, the PostgreSQL Project, is implemented instead as it is better supported. With the introduction of cdrtools, many tools in the system have been renamed. The packages genisoimage, wodim, and icedax, for example, have been renamed to mkisofs, cdrecord, and cdda2wav, respectively. The web server software, nginx, has been added to the SLE 15, and UnRAR, the command line application for the extraction of .rar files is replaced with unar as the former is not free despite being labeled freeware. In addition to all of this, the system time and server time NTP synchronizer, ntpc, is replaced with an upgraded daemon fit for the same task, Chrony. The previously employed message passing interface, the MPI 1, has been moved back as a legacy module and the MPI 2 is now in effect with the onset of the MPI 3. The lshw machine data analyzer has been added which runs the “about” information collection of the device and its firmware, and the kernel manipulating Program creation toolkit, the BPF Compiler Collection (BCC) is also a new addition to the SLE 15. In addition to these major inductions, 6 updates have been made to resident packages according to the SLE 15 release notes and 4 significant packages have been removed entirely.
