Establishment need to use the server, the server purchase process, in addition to the common CPU, memory, disk, bandwidth configuration, users need to select the operating system on their own, most cloud servers using Windows Server or Linux operating systems: 
Windows system
Windows server is a proprietary operating system designed for the server, including server applications developed by Microsoft, such as IIS Web server, support for virtualization tools, including firewalls and security tools. Window System user interface and development environment is object-oriented, easy to understand, learn and use. Windows is a single-user, multi-tasking operating environment, allowing users to simultaneously run multiple applications, or in a program to do several things at the same time.
There are several versions of Windows systems: Win 2003 earlier appearance, but with the continuous upgrading server hardware environment, Microsoft has stopped the basic version of the security update, and therefore no longer included in the recommendation. Now more mainstream version is win2008, relative to the former seem more mature, or whether it is compatible network optimization aspects are better.
Win2012 the original system extends the capabilities, both openness, scalability, security, high performance, easy to operate features and other advantages, but the application penetration rate has yet to be improved.
Linux system
Linxu is designed for multi-user server environment and to build an operating system, users can achieve different common landing systems, resource sharing is also more fair. Linux runs stable and efficient, and there is a large community of users and support, can quickly find loopholes in the system, the rapid release security patches, in addition to support a large number of high-quality open source software. However, the Linux-based operating system for higher technical requirements for small businesses or the average user, there are some difficult to manage.
Linux has a large number of releases available, each release provides a complete server Caozuojitong and a manager that allows users to easily install, such as a Web server or e-mail services like software, commonly used distributions such as CentOS, Ubuntu and Debian. CentOS is an Enterprise-class Linux distribution, stable, small footprint, simple configuration; Ubuntu has a strong source software support, good compatibility, but mainly to the main desktop applications; Debian places known for stability, the whole system is very basic core small, for small memory, preferred Debian.
How to choose the operating system
you choose which operating system in the process of establishment of the station is more appropriate? Mainly to see the practical application requirements. In general, can be selected according to the site development language, database type, and user habits: If the development language for the
ASP, .NET, HTML, database ACCESS, SQL Server, select Windows system; if the development language is PHP , HTML, database MySQL, please choose Linux system; if you need another significant development of alternative linux system, more accustomed optional windows system graphical interface.
What if the wrong system how to do? Do not worry, you can always request a replacement to the service provider.
Since the system is equivalent to reinstall the system disk will be formatted before, there is the risk of missing files, cloud 56 small advice can back up important data in advance, or choose to keep the data disk reloading; however, when the user selects the database version or before reinstalling the operating system template and inconsistent service can not start the problem may occur, then the best first back up data to a local server, choose not to retain data reloading.
In addition to the case of the wrong system, when the system uses a long time, run slower, or from viruses, sudden collapse, it can also be resolved by reinstalling the system.
