Linux server operating system: foreign + domestic

  

Faced with powerful Microsoft and early NetWare, Linux server operating system can be said to be a rising star in the server operating system, Linux is a free and open source Unix-like operating system, But it can't be said that it is a variant of Unix. Linux relies on security and stability, making it a big advantage in the enterprise server field.

Linux Enterprise

domestic: Red Hat and Red Flag series
Linux business in China, a large part is due to the government to promote the adoption due to the need for data security, Linux with the basis of developing nag source code has become the government's first choice. The biggest profit for the government is undoubtedly the red flag and the most popular Red Hat series. The two roles in the actual application are very similar, dealing with icons and details. These two Linux versions are basically the same in core technology.
Advantages: Open source code and strong security are valued by many departments that need high security protection. Stability and compatibility give them a powerful development momentum.
Disadvantages: Because it is based on the development and patching of Unix systems, this determines the limitations of its compatibility, and the code operation of Linux makes many professionals discouraged, resulting in its application and maintenance process. The cost and professionalism required are higher.
Foreign: SUSE Linux
If Red Hat and Red Flag are promoted by the official use of the Chinese government, then SUSE Linux wins the market by virtue of its security and stability. SUSE Linux is maintained by the openSUSE project. The main goal is to make SUSE Linux the most accessible and widely used Linux, and to be the best user Linux desktop environment. This project is funded by Novell. SUSE is exactly called OpenSuse. SUSE is Germany's most famous Linux distribution and enjoys a high reputation all over the world. YaST, a self-developed software package management system from SUSE, is also well received. SUSE was acquired by Novell in late 2003. At present, Novell has used SUSE Linux all over the company. It is believed that the technical and economic strength of Novell will bring more vitality to SUSE. The SUSE 9.0 version is a fee, and the 10.0 version is free. This makes some users confused. However, SUSE is still a very professional and excellent distribution. SUSE Linux has always been known for its gorgeous user interface.
Advantages: Professional, easy-to-use YaST package management system, secure AppArmor (features and SELinux with RedHat and other distributions, each with its own merits), the system itself combines German quality engineering.
Disadvantages: Although there is no significant improvement in software compatibility with previous software, because there are not many software developers supporting Linux systems in the market, it continues the Linux compatibility temporarily worse than Microsoft. characteristic.
Summary: Red Hat and SUSE are the two main players in the Linux market. They all offer certification opportunities to end users and partners. Red Hat's RHCE (Red Hat Certified Engineer) will be promising in the market after some real-world cases and is considered one of the best IT certifications. SUSE also offers a similar certification CLP. The Linux server version of the operating system will continue to occupy the server operating system market with its security and stability, and it is still a force to be reckoned with!
