1. 阿帕奇：
Apache 是一个开源 Web 服务器。它由 Apache 小组开发，最初于 1999 年 3 月 25 日发布。它主要用于 Unix、Linux 和 Solaris 平台。 Apache 是世界上使用最广泛的 Web 服务器应用程序。它非常安全、快速和可靠。它是一个基于进程的 Web 服务器应用程序，可创建一个新线程。它提供了一个用于身份验证和自定义响应错误和问题的数据库。它已由开发人员和用户使用多个目录索引指令进行彻底测试。
2.Nginx：
Nginx 是由 Nginx.inc 开发并于 2004 年 10 月 4 日首次发布的 Web 服务器。Nginx 也可以用作反向代理服务器，它修改来自客户端的请求并将请求发送到代理服务器。它还充当反向缓存并有效处理静态文件，如 JS 文件、CSS 文件等。它提高了内容和应用程序的质量和安全性。它是一个开源的快速、轻量级和高性能的 Web 服务器，可用于提供静态文件。一些使用 Nginx 的公司包括 IBM、GOOGLE、GITLAB、DuckDuckgo 等。
Apache 和 Nginx 的区别：
| S.NO. | Apache | Nginx |
|---|---|---|
| 1. | Apache is an open-source web server. | Nginx is a web server. It is also used as a reverse proxy server which revices the request from client and send the request to proxy server. |
| 2. | It is mostly used for Unix, Linux, Windows and Solaris platforms. | It is mostly used for Unix like systems, and does not completely support Windows. |
| 3. | It was developed by Apache group and initially released on 25 March 1999. | It was developed by Nginx.inc and initially released on 4 october 2004. |
| 4. | Apache is written in C and XML. | Nginx is written in C language. |
| 5. | It is designed for web server. | It is designed for proxy server as well as web server. |
| 6. | In heavy web traffic, it cannot support multiple requests. | It can support multiple client requests with limited hardware resources. |
| 7. | In Apache, modules are dynamically fixed that make it more complex. | In Nginx, modules cannot be loaded dynamically as there is a core software in which they are complied . |
| 8. | It follows Multi-Threaded approach to process client requests. | It follows Event-Driven approach to process client requests. |
| 9. | In Apache, there is a dynamic content in web server itself. | It does not support provide dynamic content. |
| 10. | Apache’s performance for static content is lower than that of Nginx. | Nginx’s performance of static content is two times faster than that of Apache as it can simultaneously run thousands of connections and it uses less memory comparatively. |
