Choosing the right server operating system is key to efficient and smooth operation. To make the right choice, you need to consider a set of characteristics and parameters. Let's understand what types of operating systems exist and how they differ from each other.
Whichever operating system you choose, it will belong to one of the following families: Linux or Windows. Before deciding on a specific operating system, you should understand what criteria to rely on. The following parameters are of fundamental importance:
Cost - you need to find out in advance how much it will cost to use a particular option (there are also free operating systems);
Reliability - the reliability of this criterion is usually confirmed by reputation among users;
Security - the presence of backups and protection systems against hacker attacks are fundamental characteristics;
Update frequency - find out how regularly new versions and all kinds of additions are published;
Ease of use - there are OSes with an intuitive interface, and there are options that only professionals with experience in system administration can handle.
Finally, it is important to decide what purpose you are using the server operating system for. For example, a one-page business card site or a large online store with online payments often require completely different options.
MAIN TYPES OF SERVER OPERATING SYSTEMS
The functioning of a server is based on the operation of a specific operating system. Several popular solutions are possible.
Windows Server
A practical proposition, especially when storing files. There is no need to compare Windows Server to the regular operating system installed on most personal computers.
Among the undoubted advantages of the server version is its versatility. Thus, the system is used for:
applications;
mail servers;
file servers.
However, the risk area for Windows Server is related to security. Most viruses are written specifically for Microsoft software, which potentially reduces the level of protection during administration. However, recent versions of the operating system are endowed with a higher level of security, and high-quality antiviruses are also produced.
FreeBSD
The oldest and most reliable operating system, the undoubted advantage of which is the lack of a fee. In this regard, ⅖ of all servers interact with FreeBSD. Reliability, quality, flexibility of settings are also among the strengths of the system.
However, this operating system loses its relevance over time, and the lack of a sufficient number of clear instructions makes administration difficult.
Debian
An OS that is a Linux distribution. It is considered universal and is used on both servers and regular personal computers.
This option is capable of providing smooth and stable operation, as it is considered a good solution for a server. However, the key drawback is that updates to this operating system occur extremely rarely.
Red Hat Enterprise Linux
Particularly relevant for corporate use, this system is popular and secure. Red Hat Enterprise Linux is characterized by its support for a commercial distribution.
Keep in mind that it can only be used on a paid basis. New versions are released every three years.
CentOS
Similar in characteristics to the previous version, but works on a free basis. Fast YUM package manager, support for all major hosting admin panels, a large number of forums with useful information about the list of important advantages of the system. Among the disadvantages, it should be noted that the necessary software is not updated frequently.
Ubuntu
A simple free option, acceptable for light workloads. Easy-to-understand instructions, instant availability, and excellent security are also advantages of Ubuntu.
The problem is the lack of choice of programs written for this operating system, which makes it difficult to use on large servers.
DIFFERENCES BETWEEN WINDOWS AND LINUX OPERATING SYSTEMS
As mentioned earlier, when choosing an operating system for a server, you should give preference to Windows or Linux options. These two groups of operating systems have a number of significant differences that play a fundamental role in choosing the appropriate solutions.
Core
For every operating system, the kernel is the most important component and therefore can be called one of the defining parameters.
In the case of Linux, the kernel is characterized by these properties:
the kernel is a monolith implemented as a single file - if you need to improve the functions, you need to use modules;
interacts with programs through system calls - thanks to the standardization of this process, software can run on different Linux platforms without changes;
has built-in drivers - as programs are placed in user space, taking into account the graphical shell, the level of security increases.
In the Windows situation, the situation is radically different. The kernel has these characteristics:
Contains a large number of DLL library fragments, each part of which carries its own functionality;
The use of system calls is completely absent;
User programs use special libraries, which in turn call functions from ntdll.dll;
The drivers are managed by the hal.dll library, each driver is individually connected to the kernel;
The system is adaptable to various programs.
Despite the high level of adaptability of the Windows kernel, it should be borne in mind that the performance of this system is significantly lower than that of Linux.
File system and disks
The difference in the functioning of Windows and Linux file systems is also significant.
Linux offers the following features:
starting from the main directory of the system partition, followed by connecting the disks located in the desired subdirectories;
sorting files in directories by type;
arranging storage devices alphabetically and partitions in numbered lists.
Files in Windows are organized with the following features:
Linux-like classification of partitions and disks, but with hidden information (we see, for example, drives C and D);
location of each program in a separate folder with settings, resources and files.
In general, the Windows file system is more user-friendly for beginners.
Settings repository
When talking about the features of storing settings, it is important to consider not only user convenience, but also security issues. In the case of Linux, settings have the following features:
stored in standard files;
applicable to all users;
In the case of software, settings are placed in hidden subdirectories.
Windows offers a slightly different solution:
settings are stored in the corresponding registry;
there is a separation of keys and branches, which allows for real-time access;
Remote change of software settings is possible.
Although both solutions are secure, in the case of Windows there is an obvious drawback - lack of portability.
In terms of storing settings, there are pros and cons for both Windows and Linux systems.
Features of program and update management
While the system is on equal footing when it comes to storing settings, the situation is somewhat different when it comes to managing updates and applications. When choosing a Linux server, keep in mind that:
available software package repositories;
There is no need to download software from the Internet, which ensures a high level of security and continuity of updates.
Windows has these characteristics:
no repositories;
the need to download and install software yourself;
independent program update (but with the need for a reboot).
Thus, Linux operating systems have more advantages in this regard.
Comparing all the features of Linux and Windows-based operating systems, we come to the conclusion that there is no clear leader. While some users are attracted by the convenience and ease of use of Windows, others are attracted by the decent management and security features of Linux.
The scale and specificity of the requirements, the level of training of the specialist who will be involved in administration, also influence the final choice.
