Why do servers use linux?

1. High stability

It is recognized in the industry that Linux servers are more stable than Windows servers; After years of experience, Linux is not as stable as running AIX on an IBM minicomputer, but it is much higher than a Windows server.

2. Low initial investment cost

Low hardware investment cost: Due to the inherent superiority of the Linux operating system over Windows, the Linux server can withstand more than 20% more load than Windows under the same hardware conditions.

Software input cost, lower: Windows server-side products** are generally relatively high, plus the client user authorization fee, is a large expense. Linux doesn't even cost a penny thanks to the open-source operating system.

3. Low maintenance cost

For entry-level system administrators, Windows maintenance costs are higher than Linux due to the ease of getting started with Windows; For professional system administrators, the maintenance cost of Linux is much lower than that of Windows.

4. The damage caused by the virus is low

Due to the congenital deficiency of Windows and the high market share of Windows on the client side, most of the viruses currently target the Windows operating system; Linux is an open-source operating system, and even if there is a targeted virus, the open source community will correct it from the bottom to fundamentally eliminate the harm caused by similar viruses in the future.

5. No need to upgrade frequently

In order to keep the enterprise profitable, Microsoft will continue to release new products; In order to maintain server stability, enterprises can only keep upgrading with Microsoft, which is time-consuming, labor-intensive, and costly. Linux, on the other hand, is much better in this regard.

6. Confidentiality

Since Windows is a commercial product, the source is closed, and we have no way of knowing what Microsoft has done in it. Linux, on the other hand, does not have this problem because it is the source of the first open operating system.

The Linux operating system itself provides a good data backup tool; Windows requires expensive third-party software to do this.

The Linux operating system can provide incremental backups within a specified period of time and complete backups at regular intervals. This strategy can be used for most enterprise data backups.

Linux, the full name of GNU Linux, is a free-to-use and freely disseminated UNIX-like operating system, whose kernel was first released on October 5, 1991 by Linus Bennadiket Tovaz, it is mainly inspired by the ideas of Minix and Unix, and is a multi-user, multi-tasking, multi-threaded and multi-CPU operating system based on POSIX. It runs major Unix tools, applications, and network protocols. It supports both 32-bit and 64-bit hardware.

Linux inherits UNIX's network-centric design philosophy and is a multi-user network operating system with stable performance. There are hundreds of different distributions of Linux, such as community-based Debian, ArchLinux, and commercially-developed Red

HAT Enterprise Linux, SUSE, Oracle Linux, etc.

1. Open source: The Linux system can be used for open source purposes, and users can not only see the Linux kernel through open source, but also modify and build it.

2. Stability: Users who use the Linux system will rarely encounter system crashes, and there will be no major accidents and problems even when they have been running for many years, and the stability is very good.

3. Flexibility: The biggest feature of the Linux system is flexibility, users can customize the Linux system, through the programming interface, add their own tools and programs to the system, you can create a user desktop that is more in line with your standards, and secondly, the shell as the largest component of the Linux system, can completely allow the running program to interact with the kernel.

4. Hardware: Compared with the Windows system, Linux has relatively low hardware requirements and does not need to be upgraded frequently.

5. Security: Only administrators and specific users can access the kernel authority in the Linux system, so the security aspect is relatively high, and the possibility of receiving it is small.

6. Low cost: Linux is a free operating system, and the cost will drop a lot, even if you buy a paid Linux system, it is very low.

7. Easy to change: You can freely change the system without restarting the server, and you don't need to buy other versions to use some specific functions.

Looking at personal choice, Linux also has its own characteristics, Linux is"It's free"There are many on it"It's free"The software, based on Linux-based parallel computing, is not only inexpensive, but also powerful, has potential, and importantly, is active**.

Its characteristics are: openness, all hardware and software developed in accordance with international standards, can be compatible with each other, can be easily interconnected; Multi-user, system resources can be owned and used by different users, that is, each user has their own resources; Multitasking, where a computer executes multiple programs at the same time, and each program runs independently of each other; Good user interface, user interface and system calls; Device independence, the operating system treats all external devices as files, as long as their drivers are installed, any user can manipulate and use these devices as if they were files, without knowing their specific form of existence; It provides rich network functions, and the perfect built-in network is a major feature of Linux; Reliable system security, Linux has taken many security technical measures, including permission control for reads and writes, protected subsystems, audit trails, core authorization, etc., which provides necessary security for users in a multi-user network environment. Good portability refers to the ability to move an operating system from one platform to another so that it still works the way it does.

Most servers use Linux system for the following reasons:

To put it simply, Linux has the following key features:

1.Open.

Openness means that the system follows the world's standard specifications, especially the Open Systems Interconnection (OSI) international standard. All hardware and software developed in accordance with international standards are compatible with each other and can be easily interconnected.

2.Multi-user.

Multi-user means that system resources can be owned and used by different users, that is, each user has specific permissions on their own resources (for example, files and devices) and does not affect each other. Both Linux and Unix are multi-user.

3.Multitasking.

Multitasking is one of the most important features of modern computers. It refers to the fact that a computer executes multiple programs at the same time, and each program runs independently of each other. The Linux system schedules every process and has equal access to the microprocessor.

Since the CPU is very fast, the result is that the launched applications appear to be running in parallel. In fact, there is only a short time delay between when the processor executes a set of instructions in an application and when the Linux schedules the microprocessor to run the program again, which is not noticeable to the user.

4.Good user interface.

Linux provides users with two interfaces: user interface and system calls. The traditional user interface of Linux is a text-based command-line interface, or shell, that can be used both online and offline on a file.

The shell has strong programming capabilities, and users can easily use it to program them, thus providing users with more advanced means to extend the functions of the system. A programmable shell is a shell program that combines multiple commands to form a shell program that can be run alone or at the same time as other programs.

Linux servers have many advantages over Windows servers, which are as follows:

1. Open source

The number one reason Linux Server is superior to Windows Server is that it is completely free and can be used as open source. Open source, you can easily view, modify, and reauthor the Linux kernel that was used to create it. With many programming interfaces, you can even develop your own programs and add them to the Linux operating system.

The Linux Server operating system can also be customized to meet usage requirements, which is not possible with Windows.

2. Stability

Linux systems have always been known for their stability, and they can run continuously for years without any major problems. In fact, many Linux users have never experienced a system crash in their own environment. Hangs and crashes are completely the norm relative to Windows.

While Windows can also multitask well, Linux can handle a wide range of tasks while still delivering rock-solid performance.

3. Safety

Linux evolved from the UNIX operating system, which was originally developed as a multi-user operating system, and is clearly stronger than Windows in terms of security. Unlike Windows, which is the primary target of virus and malware attacks, Linux Server only has access to the Linux kernel for administrators or specific users, and Linux servers are not vulnerable to frequent attacks, and any vulnerabilities found are fixed by a large group of Linux developers as soon as possible.

4. Hardware

When comparing Linux Server to Windows Server in terms of hardware, Windows needs to upgrade the hardware frequently to meet various performance requirements. Linux, on the other hand, has low hardware requirements, does not require frequent hardware upgrades, and performs very well regardless of the system architecture or processor.

5. Flexibility

Linux is one of the most flexible operating systems in the world, and there is no one where you can customize the system according to your needs. With Linux, you can install the GUI interface as much as you want or just use the terminal management server; With Linux, you can choose from a variety of jobs and utilities to manage all server-related activities, such as adding users, managing services and networks, installing new applications, and monitoring performance.

6. Freedom

In the case of Linux, you will not be forced by commercial vendors to impose products and services, and users are free to choose the products that suit their needs. It is this freedom that has led large companies like Amazon and Google to opt for Linux-based servers to provide their services.

Linux is not only very efficient and stable as a server system, but also does not have to worry about copyright issues and does not have to pay. Cloud Helper's server management panel can be supported by both Linux and Windows systems, effectively improving O&M efficiency.
