Apache and IIS are the two most popular web server software, so what are the differences between them? The following article will introduce to you the differences between IIS and Apache. I hope it will be helpful to you.

What is the difference between IIS and Apache

The difference between IIS and Apache:

1. Stability

WWW services must be functioning properly at all times, and a website must be open to the public 24 hours a day, seven days a week. Therefore, stability is the focus of comparison between IIS and APACHE.

IIS often encounters 500 errors in actual use, and sometimes inexplicable suspended animation occurs. Users need to restart the IIS service from time to time to ensure the normality of the website.

Apache is more complicated to configure than IIS, but once it is set up, it can work for a long time. Large websites use APACHE as their WWW service providing tool. All configurations of APACHE are saved in the configuration file. When used, they are executed exactly according to the information recorded in the configuration file. Inexplicable suspended animation generally does not occur.

Conclusion: APACHE is stable, IIS sometimes fakes death, and the former has the advantage.

2. Extensibility

Extensibility refers to whether the WWW service provision tool can be applied to multiple occasions, multiple network conditions, and multiple operating systems.

IIS can only be used under Microsoft's Windows operating system. Without Windows, it will accomplish nothing. Not portable to other types of operating systems.

APACHE is an all-rounder. It is not only used in windows, but can also be used for various operating systems such as unix, linux and freebsd. Moreover, the configuration steps of different operating systems are basically similar, and the portability is very high.

Conclusion: IIS can only run under windows, and apache has a wide range of applications. apache wins.

3. In terms of security

I often see news that a certain website has been hacked or a certain website has been uploaded by illegal users. For providing services to others, For a website, security is the most important thing. If a website cannot even guarantee its own security, who is willing to browse and use it?

Early IIS had big security problems. If the default settings were used, hackers could easily take advantage of it. However, in IIS6, Microsoft has made significant improvements in security. As long as the operating system patches are updated in a timely manner, the security factor of the website can be improved as much as possible. In particular, IIS6 and the .net platform depend on each other, making security almost perfect.

APACHE has always done a good job in terms of security, because many users use apache under Linux, so the characteristics of the operating system make apache under Linux have an innate protective umbrella, and the security is natural.

Conclusion: Previous versions of IIS6 have security risks, and IIS6 is as safe and reliable as APACHE. IIS6 is tied with APACHE.

4. Openness

The so-called openness refers to whether the source code of the program is open. As we all know, IIS is part of the WINDOWS system, so its source code is Nothing is open. Apache is different. Initially, it served Unix-like systems, so it is completely open source. Anyone can analyze his code, find a vulnerability in it, and issue a patch to close it.

Because of the openness of APACHE, its security has been greatly improved.

Conclusion: IIS does not open source code, APACHE does open source code. The latter won.

5. In terms of ease of use

The ease of using a tool directly affects the number of its users, especially web publishing tools. After all, many companies want to have their own websites, but they don't want to hire highly paid network administrators to maintain them. Therefore, you must find tools that are relatively easy to use to build your own site.

IIS is relatively simple to open. It is easy to make IIS work and publish websites to the outside world. However, administrators are prone to misconfiguration and misoperation. But generally speaking, IIS is very easy to learn, but it may be very difficult to learn it well.

APACHE is more difficult to use than IIS and requires people with certain computer and network skills to use it. Its configuration is not graphical, and we need to edit the configuration file to achieve it. But from the perspective of APACHE settings alone, it is not difficult as long as we set the parameters strictly in accordance with the help file.

Conclusion: IIS is easy to install but difficult to master. APACHE is relatively difficult to install, and it is not easy to master it. IIS has a slight advantage.

6. In terms of programming

In order to make the web page more colorful, more beautiful, and more interactive, experts have developed a variety of components and controls for us. So do these controls run normally under IIS or APACHE?

The Mod Rewrite function under APACHE is very powerful, while the ISAPI Rewrite in IIS requires special development, which is generally not possible for beginners. APACHE can use Subversion WebDev and .htaccess functions, and can also use ForceType.

In addition, IIS's support for FastCGI is not very good, so some CGI and PHP programs run very slowly, far less than apache.

Conclusion: Different components are used in different environments, because the choice of IIS or APACHE is determined by the working environment. There is no distinction between the two.

7. Supported languages

Since there are many languages ​​used to build websites and forums, such as ASP, PHP, JSP and other languages. So do IIS and APACHE support them?

IIS is very stable for ASP, especially .net, but it is more troublesome for PHP and JSP. PHP needs to be repeatedly configured to be supported on Windows 2003. APACHE can support the languages ​​mentioned above very well, and there is no problem running ASP, PHP, and JSP.

Conclusion: APACHE supports many languages. It is a bit troublesome for IIS to support PHP and JSP, which requires certain configuration. APACHE wins.
