To optimize the server for the operating system, Apache uses the Multi-Processing Module (MPM). Each child process creates a pre-determined number of server threads that handle incoming requests. The main process is the parent process, while others are child processes. The purpose of those processes is to share the workload.

The modules are either statically compiled or loaded dynamically.Īt boot time, Apache starts multiple server processes. The Apache HTTP Server features a small server core and several modules. Commercial support by 3 rd party providers

Nginx (pronounced engine-x) is an open-source web server developed by Nginx, part of F5, Inc.Īs an HTTP server, Nginx utilizes a highly scalable event-driven (asynchronous) architecture allowing for high performance and a small memory footprint. For basic Apache web server management, learn how to start, stop, and restart Apache. For Ubuntu, read How to Install Apache Web Server on Ubuntu. Note: The Apache HTTP Server works best on Linux. This interaction includes encryption, virus scans, and compression of both static and dynamic content. The modular architecture of the server also allows for features such as modular protocol handling.Īnother essential feature of Apache’s architecture are filters, which allow modules to interact with the content created by other modules. It was initially designed as a process-based web server, but as of version 2.0 and the introduction of Multi-Processing Modules, it can be configured as both a process-based and threaded server. The Apache HTTP Server (or Apache for short) is an open-source web server software developed by the Apache Software Foundation.
