The recently released Super 500 Top 500 list shows that all the supercomputers on the list are running the Linux operating system. Despite the unsatisfactory performance of the Linux operating system on the desktop, its performance as an operating system on servers, mainframes, and supercomputers running in global data centers has made many other competitors look back.
Linux was first used by the Top 500 supercomputer in 1998, when the supercomputer was still dominated by the Unix operating system. Since 2003, supercomputers have been dominated by Linux systems, and by 2004 Linux had dominated supercomputers. In the Top 500 list released in the first half of this year, two Chinese IBM POWER computers run the AIX system, and they have fallen out of the list released in November, so the result is that all the supercomputers of the Top 500 are running Linux. .
Compared to other operating systems, Linux is free and open source, in addition to strong stability and high security, which is the reason for the lower cost of using Linux systems as a whole. This article will be based on factors such as data center performance and reliability associated with supported features and hardware, ease of installation and use, licensing-related ownership and maintenance-related issues, and accessibility to commercial support. Excellent top ten Linux server distributions.
1. Ubuntu
At the top of the list is Ubuntu, a Debian-based open source Linux operating system developed by Canonical. There is no doubt that it is the most popular Linux distribution of the moment, and there are many other distributions derived from Ubuntu. Ubuntu servers are very powerful for building high-performance, highly scalable, flexible, and secure enterprise data centers. In addition, it provides excellent support for services such as big data, visualization and containers, and the Internet of Things. Ubuntu servers can run on x86, ARM, and Power architectures.
Get business support and services with Ubuntu Advantage, such as system management tools for security auditing, compliance, and Canonical livepatch services that help you apply kernel fixes and more. In addition, there is support from a strong and growing community of developers and users.
2. Red Hat Enterprise Linux (RHEL)
The second is Red Hat Enterprise Linux (RHEL), an open source Linux distribution developed by Red Hat and a commercial distribution. RHEL is based on Fedora, a community-driven project, and a large amount of software on RHEL was first developed and tested on Fedora.
The RHEL server is a powerful, stable, and secure software that provides modern data center support for software-oriented storage. It also supports cloud, internet of things, big data, visualization, and containers. RHEL servers support machines on x86, x86-64, Itanium, PowerPC, and IBM System z architectures.
3. SUSE Linux Enterprise Server
SUSE Linux Enterprise Server is an open source, stable, and secure server platform built by SUSE to support physical, virtual, and cloud-based servers. It is ideal for cloud solutions that support visualization and containers, and can run in ARM SoC, Intel, AMD, SAP HANA, z Systems, and modern hardware environments for NVM Express. Users can get all kinds of technical support and services through SUSE subscription service, including priority support, full-time engineers and so on.
4. CentOS (Community OS) Linux Server
CentOS is a derivative of RHEL. This is a Linux distribution with full community support and is therefore operationally compatible with RHEL. If you want to use RHEL and don't want to pay a lot of money for the subscription service, then consider using CentOS. And because it's free software, you get support from other community members, users, and online resources.
5. Debian
Debian is a free, open source, and stable Linux distribution maintained by the user. It has more than 51,000 packages and uses a powerful package management system. It basically supports most of the computer architecture, including 64-bit PC (amd64), 32-bit PC (i386), IBM System z, 64-bit ARM (Aarch64), POWER processor, etc. Used by commercial companies, non-profit organizations, and government agencies. Debian has an error tracking system that allows users to get support for Debian by reading the documentation and free web resources.
