Apache vs. Nginx: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 23, 2023
Apache and Nginx are web servers; Apache uses a process-driven approach, while Nginx employs an event-driven architecture.
Key Differences
Apache, under the Apache Software Foundation, has been one of the most widely used web servers for decades. Nginx, on the other hand, emerged as a lightweight, high-performance alternative to Apache, particularly for handling static content and acting as a reverse proxy.
While both Apache and Nginx serve web content, their architectural designs differ significantly. Apache uses a process-driven or thread-driven model, where each client connection equates to a separate thread or process. Nginx adopts an event-driven approach, allowing it to handle many connections simultaneously without creating a new process for each.
In terms of performance, Apache can become resource-intensive when handling a high number of simultaneous connections. This is because of its process or thread for each connection model. Nginx, with its event-driven architecture, can manage high traffic with minimal memory overhead, making it particularly effective for serving static content efficiently.
Extensibility is another area where Apache and Nginx diverge. Apache boasts a modular architecture, allowing developers to add functionalities using modules. Nginx also supports modules but, traditionally, they needed to be included at compile time. Recent developments, however, have begun to offer dynamic module loading for Nginx.
